Looking Back at New York's Weather: August 17

 

1920 (Tuesday)

Today had the last low in the 70s of the year, just nine days after the first 70-degree low was recorded - the shortest span on record between first and last.  During this brief span, eight of the nine days had lows in the 70s.

1943 (Tuesday)

Today was the end of a 41-day streak of highs of 80° or warmer.  The average high during this nearly six-week period was 87.4° (compared to the average high of 84°); fourteen days had highs in the 90s.  At the time, this was the longest such streak on record, passing one of 37 days set in 1917.  However, this streak would be surpassed one year later.  (And that streak would hold sway for 71 years.)

1944 (Thursday)

Today was the last day of an eight-day "super" heat wave, in which every day had a high temperature of 95° or hotter.  The average high during these days was 97°.  Today's high of 95° was a record (later tied in 2015), as were three other days during the heat wave (including 8/11's high of 102°).

 

 

1974 (Saturday)

2.86" of rain fell between 3-8 PM, a record for the date, accounting for half of the month's total rainfall.  Nearly half of today's rain fell between 6-7 PM (1.29").

1979 (Friday)

At a chilly 56°, this morning's low was a record for the date.  Today was also the seventh day in a row with cooler than average temperatures. 

1984 (Friday)

This morning's low of 69° was the first time this month that the low fell below 70°.  During these days, lows averaged 73°, four degrees above average.

1987 (Monday)

The day's high reached 94°, eleven degrees hotter than a typical mid-August day.  This high would be replicated tomorrow, and it would be the last day in the 90s of the year (there were 22 in total).

1988 (Wednesday)

The 0.14" of rain that fell today was the first rainfall this month.  Today was also the 24th day in a row with a high temperature of 85° or warmer, the longest such streak in the 1970-2021 period (later tied in 1995).

1992 (Monday)

0.62" of rain poured down in an hour (11:24 PM-12:24 AM), and 0.92" fell in a two-hour period (10:42 PM-12:42 AM).  Total rainfall for the day was 1.52".  Not only was it damp, but cool, as the day's high temperature was just 68°, fifteen degrees below average.  This was the third day in a row in which the high and low were stuck in the 60s, just the fifth (and last time) this has happened (through 2021).

 

  

1993 (Tuesday)

3.20" of rain fell in a 12-hour period that began yesterday evening.  What fell from this storm was comparable to the amount that fell in all of June and July.

 

 

1994 (Wednesday)

For the third year in a row an inch or more of rain fell on this date, the only time this has occurred.  Today's rainfall totaled 1.00".

1997 (Sunday)

Today, with a high of 93°, was the last 90-degree day of the year.  In total, a dozen days reached 90° or higher, well below the average of eighteen.

1998 (Monday)

The 2.38" of rain that fell today accounted for almost all of the rain that fell this month (2.78").  1.49" of it fell in just two hours, between 2-4 PM.  This was also the fourth year out of the past seven in which an inch or more of rain fell on this date.

2009 (Monday)

Today's high/low of 92°/75°, nine degrees above average, made this the hottest day of a cool summer.

July 2022 - Just The Second July With Highs of 80+ On Every Day

 

 

A typical July in New York has six days with highs cooler than 80°.  However, July 2022 had no such readings and joined July 1944 as the only other July in which every day had a high of 80° or warmer (it also happened in August 2015).  The coolest high was 81°, which occurred twice.  Overall, July 2022 was two degrees warmer than average (high/low of 87.3°/71.8°) and ranks as the 13th hottest July on record; it had the 8th warmest low, and tied for 16th warmest high.  

 

The number of days with highs of 85° or warmer was 25.  Only five other Julys have had more (in 2019, 2010, 1993, 1966, and 1944) and four others have had 25.  The hottest reading was 95°, which occurred on three days, and the warmest low was 79°.  Of the ten Julys with 25+ days of 85+, July 2022 had the fewest days of 87+ as it had 10 highs of 85° (7) and 86° (3).  

 

 

The coolest low was 65° on the Fourth of July.  Only five other Julys have had a chilliest low this mild or milder (the most recent was two years ago when the coolest low of 67° was the mildest coolest July reading on record).

 

During the first half of the month it appeared July's big story would be the very dry conditions as just 0.33" of rain was measured in Central Park through 7/15 - the least to fall in the first half of July since July 2002.  And while a large portion of the metro area continued to suffer through dry conditions in the second half of the month (Newark's July total was just 0.55", JFK's was 1.10"), 4.22" fell in Central Park, which was double the typical amount.  As a result, July's total rainfall ended up being very close to average (0.05" below).  Much of the rain fell from isolated strong thunderstorms. The most to fall on one day, 1.85" on 7/18, was a record for the date. 

 

A six-day heat wave, from 7/19-24, was the longest since the summer of 2013.  The average high/low was 94°/77°.  In addition to these six days, there were four other days with highs in the 90s (on 7/1 and 7/12-14); the total of 10 was three more than average.  The hottest day of the month occurred on the last day of the heat wave, with a high of 95°/79°.  Two other days during the heat wave, 7/20 and 7/23, had  highs/lows of 95°/78°.  (In addition to the large disparity in rain compared to Central Park, Newark also had a reecord-setting five-day streak of triple-digit highs).

 

 

Typically, June averages six lows in the 70s/80s and July averages 16.  This summer the respective numbers were one and twenty-four.  This increase of 23 days compared to June is the greatest increase from any June with 0, 1 , or 2 lows in the 70s.  Only July 2020 and 2010 have had more lows in the 70s/80s than July 2022 (tied with three other years that had 24 such lows).

 

Finally, the 4.55" of rain that fell was the eighth time this amount was a monthly precipitation total.  The most recent occurrence was in April 2019, and there was another July with this amount in 1916. 

 

Here are July recaps from previous years:

June 2022 Weather Recap - Largely Uneventful, on the Dry Side

 

June 2022 was slightly cooler than average (-0.6 degrees), and rainfall of 2.92" was 1.62" below average.  The first half of the month was 1.4 degrees above average, the second half was 2.6 degrees below average (ironically, the month's four warmest highs and lows were all in the second half of June).  This was the third June in a row with less than three inches of rain, but this June had more than the previous two (2.62" in 2021, 1.76" in 2020).  More than 70% of the month's rain fell in the first nine days of the month; less than an inch fell in the last three weeks.  Other observations:

 

• The month's hottest reading was 90° on 6/25, which came six days after the coolest reading (54°).

 

• The warmest mean temperature came the day after the hottest high.  At 89°/74°, it was also the most above average day of the month (+7 degrees).  The low was the only low in the 70s during the month.
  

 

• Father's Day had the coolest low in  June (at 54°, it was the coolest reading on Father's Day since 1958).  And with a high of 73°, it was the first Father's Day in ten years not to have a  high of 80° or warmer.  A week later, the low on the day of the Gay Pride Parade, 74°, was the warmest of the month (and tied for second warmest low on Gay Pride Sunday).

 

• In between highs of 88° on 6/17, and 90° and 89° on 6/25 and 6/26, the seven days in between were six degrees cooler than average, with a high/low of 75°/60°.

 

• Every reading in June between between 71° and 90° was a high temperature in June, except for 87°.

Analysis: Temperatures Most Likely to be the Coldest or Hottest of Each Month

 

 

Looking at all of the months of every year since the reporting of weather conditions  began in Central Park in 1869, the temperature that has the distinction of occurring the most times as a month's coldest reading is 52° in June, which has occurred in 25 years (most recently in 2016), or about once every six years.  And the daily high that's most frequently been the hottest of any month is 94° in July as well as in August; it's been the hottest reading in those two months 22 times (most recently in 2017 and 2021, respectively).

 

 

 

Looking across months, the temperature that has had the most designations as hottest reading of a month is 92°, which has had that distinction 76 times across six months.  (Second most is 94°, which has been hottest 72 times across five months.)

 

 

By contrast, the daily low temperature with the most designations as coolest is 57°, which has been the coolest reading 45 times across four months.  Second most is 41 times for the lows of 17° and 52°, occurring in five months and four months, respectively.

 

 

Here are the greatest concentrations by month:

August - 80% of its hottest readings have been between 89°-96° (an 8-degree range)

June - 75% of its hottest readings have been between 89°-96° (an 8-degree range)

June - 75% of its coolest readings have been between 49°-55° (a 7-degree range)

May - 73% of its coolest readings have been between 40°-46° (a 7-degree range), and 50% have been between 41°-44° (just a 4-degree range) 

 

MISCELLANEOUS OBSERVATIONS

• February and March have had the most different temperatures that have been coldest (both with 30) or warmest (both with 34), while June has had the fewest (15 and 19), with July having practically the same amount (16 and 19) .

• The most frequent chilliest temperature in July, 60° (22 times), last happened in 1995, which is the longest current hiatus of any month for a temperature that has been coldest or warmest.  But despite this lengthy hiatus, it's still comfortably ahead of 58° and 59°, which have both happened 19 times.  Looking at warmest reading, the last time February's most frequent mildest reading occurred (58°) was in 2005.

• For five years in a row (1989-1993), September's chilliest reading was 44°.  In five of the six years between 1946-1951 the hottest temperature in July was 94° (the outlier was 102° in 1949).  Also in July, five of the six years between 1973-78 had 58° as the coolest reading; the outlier was a low of 59° in 1974. 

• Half of the 16 occurrences of the low of 13°, which is the most frequent coldest low temperature in December, were concentrated in the 15 years between 1886-1900.  The other eight 13° readings occurred in the course of the other 137 years.

• Despite it being April's most frequent coldest low, there was a 31-year period between 1874-1904 when the low of 33° wasn't the coldest reading.  And the low of 42° in May (tied for the month's second most frequent low) had a hiatus of 36 years between 1893-1928.
  

 

May 2022 Weather Recap - Late First 80, Followed by Early First 90 & First 70

 

 

 

May 2022 was 0.8 degrees milder than average, and rainfall was somewhat above average (4.52").  The coolest reading was 45° on 5/7 and 5/8, the hottest was 93° on the last day of the month.  The last time the temperature was this hot in May was in 2000 (on 5/7); the last time it was hotter was in 1996 (96° on 5/20).   

 

The first 20 days of the month were about a degree below average, but then from May 21 onward temperatures were four above average.  For the entire month, eight days were five degrees or more warmer than average, four were five degrees or more cooler than average.  The most above average day was 5/22, with a high/low of 89°/72° (16 degrees above average); the most below average day was 5/7, with a high/low of 50°/45° (13 degrees below average).

 

The year's first reading of 80°+ occurred very late, on 5/21, the latest since 1988 and tenth latest on record; that date also had the year's first reading in the 90s, (90°),  just the fourth time that the first 80 and first 90 shared the same date.  Regarding days in the 90s, since 1960 Mays with two or more days with highs in the 90s occur about once every three years.  (Before 1960, it happened once every seven years.) 

 

The day after the first 80/90, Central Park had its first low in the 70s (72°), which was about two weeks ahead of schedule (the first 90 was about a week ahead of schedule). 

 

May's rainfall of 4.52" was 0.01" less than what fell in April.  This was the tenth time there was a 0.01" difference between consecutive months.  The previous time it occurred was in January and February 2016 when 4.41" and 4.40" was measured.  There have been five pairs of consecutive months with the same amount of precipitation (the last time it happened was in September and October 1997).

 

Finally, Memorial Day's high of 84° was the warmest reading on the holiday since 2015 (when it was 85°), while the high of 58° on Mother's Day (5/8), was the chilliest since 2018 (when it was 54°).

Today in New York Weather History: May 21

 

1924

On a showery day, the high/low was only 50°/47°.  The high was 20 degrees below average.

1971

Although just 0.03" of rain fell today (between 3-4 PM), it was the first measurable rainfall on this date in 17 years.  The day was gray and coo,l with a high of only 60°.

1985

Heavy rain fell between 5-11 PM, amounting to 1.60".  During one 15-minute period (between 6:55-7:10 PM), 0.48" of rain poured down.

1996

This was the second day in a row with a record high as the mercury topped out at 93°.  The next 90-degree day wouldn't be for another two months (and it would be the only other 90-degree day of the summer.) 

 

2002

This was the last of four consecutive days with morning lows in the chilly low 40s, well below the average of 55°.

2012

After four days in a row of sunny and mild weather, today was a gray, rainy Monday.  1.40" of rain fell, with a particularly heavy downpour occurring during AM rush hour, with 0.57" measured between 9-10:00.

2013

Today was just the second 80-degree day of the year, coming six weeks after the first (4/9).  This was the greatest number of days between the first and second 80-degree day in eight years, when there was a gap of 45 days.  (The longest gap, in the years since 1900, was 58 days in 1928).  Today's high of 86° was the warmest reading since the first week of September 2012.

 

 

2022

At long last the temperature reached the 80s for the first time this year, the latest date for this occurrence since 1988.  This is the tenth latest date for this occurrence on record.  And with a high of 90°, this was just the fourth year to have the first 80 and first 90 occur on the same day (joining 1918, 1927 and 2010).  This was the first time a reading was in the 90s in May since 2018.  Besides the heat, the air was oppressive, with afternoon dew points in the 68-70° range.  The morning low of 62° was the coolest on a day with a high in the 90s since 2010, when there was a low of low of 56° on 4/7 (the earliest date on record for a reading in the 90s).

April 2022 Weather Recap - Rainy, Then Dry

 

April was 0.9 degrees chillier than average and somewhat rainier (despite there being practically no rainfall in the month's last 11 days).  The chilliest reading was 38° (on 4/2), the mildest was 79° (4/14).  The last time the chilliest reading was this mild was in 2012.  Only two other Aprils have had a milder reading for their coldest reading: in 1878 (42°) and 2010 (40°).  The month's temperature range was 41 degrees, well below the usual range of 50 degrees (since 1980, 32° to 82°).  On the day the high reached 79° in Central Park, the high at Newark Airport soared to 88° (and it was in the low 70s at LaGuardia and Kennedy airports).  

 

The month's rainfall of 4.53" was similar to that of April 2020 (4.49") and April 2019 (4.55").  Much of the rain fell from two storm systems that brought 1.15" on 4/7-8, and 2.09" on 4/18-19.  Just 0.02" of rain fell between 4/20-30, which was the least to fall in the last third of April since 1942, when no measurable rain fell after 4/11 (that April is the second driest on record).   

 

Six days had highs in the 70s, an average number, with five of them on consecutive days (4/12-4/16).  The average high of 73° during the streak was twelve degrees above average.  This was the lengthiest such streak in April in 11 years.  The streak ended the day before Easter Sunday, which, with a high/low of 51°/41°, was the chilliest since 2009.  

 

Finally, the last three days of the month had afternoon humidity levels that bottomed out at 11%, 9%, and 14%.  The 9% reading on 4/29 tied for the third lowest in the years since 2000.  This was the most arid three-day streak since March 28-30, 2007.  Very low humidity was also reported on the 15th and 22nd (13% and 15%, respectively).

Months With Warmest & Coldest Readings Just A Few Days Apart

 

 

For the purposes of this analysis, I've gathered together months that had their coldest and warmest temperature one or two days apart.  On average, this has happened about once every two-and-a-half years.  The difference between the coldest and warmest reading has been, on average, 42 degrees (ranging between swings of 29 and 61 degrees).  I've limited the months in this analysis to those with "solo" occurrences, i.e., months in which the hottest and coldest temperature occurred on just one date.  Through March 2022, there were 58 months that met this criterion.  The last time it happened was in Nov. 2009, when the month's coldest temperature occurred on 11/7 (35°), and mildest reading on 11/8 (69°).  Here are a few other observations:

 

• By month, February has had the most instances (nine), while September had the fewest (one).  By season, winter has had 20 such months, spring and summer have each had 14, and fall has had 10 months.
  

 

• Although the average time between occurrences has been 2-1/2 years, in 1961 it happened in consecutive months (May and June).  And there have been three instances in which this type of month was just a month apart from the other:  Oct./Dec. 1871; Dec. 1882/Feb. 1883; and Aug./Oct. 1894.  (There are no instances in which a month's temperature extremes occurred on the same day). 

 

• We're presently in the midst of the longest hiatus, which started in December 2009.  This is in contrast to the 15-year period between 1887-1901 when there were 13 months which had their warmest and coldest readings 1-2 days apart.  (Including five consecutive years, 1891-1895.)
  

 

GREATEST SWINGS IN A MONTH'S WARMEST-COLDEST TEMPERATURE WHEN 2 DAYS APART

>  March 1987/ 61 degrees/ from 76° to 15°

>  March 1988/59 degrees/ from 17° to 76°

>  Dec. 1871/ 57 degrees/ from -2° to 55°

>  Feb. 1967/ 56 degrees/ from 4° to 60°

>  April 1880/ 54 degrees/ from 26° to 80° 

 

GREATEST SWINGS IN A MONTH'S WARMEST-COLDEST  TEMPERATURE WHEN 1 DAY APART

>  Jan. 1934/ 52 degrees/ from 58˜ to 6°

>  Jan. 1913/ 45 degrees/ from 18° to 63°

>  June 1961/43 degrees/ from 96° to 43°

>  Feb. 1947/ 43 degrees/ from 50° to 7°

 

Finally, there have been nine months in which the temperature extremes occurred on the first and last day of the month, most recently in June 2009.

 

 

 

 

March 2022 Weather Recap: Somewhat Mild & Dry

 

 

March 2022 was the 16th mildest March on record in New York.  (March 2020 and 2021 are among the 16 that were milder.)   The month was 2.5 degrees above average, with the high and low being 3.7 and 1.2 degrees above average, respectively.  This March would probably have ranked among the ten mildest if it weren't for four cold days:

 

•             March 4 -  37°/21°, 11 degrees below average 
•             March 13 - 35°/22°, 13 degrees below average
•             March 28 - 33°/23°, 19 degrees below average 
•             March 29 - 38°/24°, 15 degrees below average

      

March 28th's high was the coldest this late into the year in 40 years, since a high of 30° on April 7, 1982.  (Temperatures rebounded on the 31st, and from late morning into the wee hours of 4/1, they were in the 60s.)  And the last time a low of 23° occurred later than 3/28 was in 1995, on 4/6.

 

 

March 7 and 18 were the mildest days of the month, with both having the same high/low of 74°/50°.  The eight-day period from March 15-22 was 12 degrees above average (high/low of 64°/46°).  This was followed five days later by a four-day stretch of unseasonably cold temperatures, from March 27-30, 13 degrees below average (41°/26°).

 

Below average precipitation, 2.39" (about two inches below average), made this NYC's 29th driest March (tied with March 1897).  Much of the rain, 1.99", fell on three days (0.56" on 3/9, 0.50" on 3/12, and 0.93" on 3/24).  Only 0.4" of snow fell (3/9), but it was the most in March in three years.  33 other Marches have had less snow.

 

There was a wind gust of 49 mph the night of 3/7, the highest gust recorded in Central Park since one of  62 mph during superstorm Sandy on Oct. 29, 2012.   

 

Finally, on 3/22 afternoon humidity drop to 11% (fourth lowest of this century).

February 2022 Weather Recap: Minimal Snow, Wide Variation in Average High & Low

 

Last winter, February had much more snow than January (26.0" vs. 2.1"), but this winter the tables were turned as February had just 2.0" compared to January's 15.3".  Although snowfall was minimal, there have been 31 other winters with even less snow in February (and two-thirds of those had less than an inch). 

 

Temperature patterns were also reversed, as February of last year was 1.7° below average and  January was 1.1° above, while this winter February was 1.4° above average and January was 3.4° below.  Feb. 2022 was the 21st mildest on record.  Five recent Februarys in 2020, 2018, 2017, 2016, and 2012, were milder.

 

 

Another very big difference between Feb. 2022 and 2021 was in its diurnal variation, i.e., the difference between the daily high and low temperature.  Last February's was just 9.5 degrees, which tied for the second smallest reported in February.  This year's however, was 16.9 degrees, which was the widest variation in February since 1990, and the third widest for any February (average variation is 12.7 degrees).  Part of the reason was that it had three days with temperature variations of 30 degrees or more; only February 1918 has had more (four). 

The difference between the average high and low of Feb. 2022 and 2021 is fascinating, as this February's average high was 6.9 degrees milder than last February, but its average low was 0.5 degrees chillier.

 

 

February's above average temperature was driven by the average high, which was 3.5 degrees above average; by contrast, the average low was 0.6 degrees below average.  Eight days had highs of 55° or milder, with four of them above 60°, including two climbing to 68° (on 2/17 and 2/23).  The first 68° was a record for the date. 

 

Looking at cold conditions, eight days had highs in the 30s or colder, and four of these days had highs of 32° or colder.  Similar to the month's warmest reading, the coldest reading (16°) was also reported on two days, 2/14 and 2/15.   (January's coldest reading also occurred on back to back days).

 

Eleven days were 10 degrees or more above or below average (seven were above, four were below).  The most above average was +23 degrees on 2/17, when the high/low was 68°/49°; the most below average day came three days before that, with a high/low that was 15 degrees below average (25°/16°).  

 

During the three weeks between Feb. 4-24, four dramatic swings in temperature occurred:

• Feb. 4-5: From 8° above average (high/low of 57°/26°), to 11° below average (27°/19°)
• Feb. 12-14: From 16° above average (59°/42°), to 1° below average (42°/25°), to 15° below average (25°/16°)
• Feb. 15-17: From 13° below average (30°/16°), to 3° above average (49°/28°), to 23° above average (68°/49°)
• Feb. 23-24: From 15° above average (68°/35°), to 6° below average (35°/29°) 

 

Finally, precipitation was very close to average, with 3.23" measured (vs. an average of 3.19").  The days with the most precipitation were Feb. 3 and Feb. 20, with 0.72" and 0.74", respectively.  The month's measurable snow fell on two days: 2/13 (1.6") and 2/25 (0.4").  Of the Februarys with two inches of snow or less, Feb. 2022 had the fourth biggest drop-off from January.

Greatest New York Weather 'Hits' of 2021

 

 

 

Nationwide, 2021's top weather events included Arctic cold in Texas in mid-February that shut down much of the state's power grid; searing heat at the end of June never before experienced in the Pacific Northwest; and a deadly tornado outbreak that Kentucky bore the brunt of on Dec. 10-11.  Meanwhile, New York's biggest story was the  consecutive months of unprecedented rainfall in July-August-September, which culminated in flooding downpours from the remnants of hurricane Ida on the night of Sept. 1, a deluge that was responsible for the deaths of nearly 50 residents of NYC and outlying suburbs (comparable to superstorm Sandy's death toll in Oct. 2012). 

 

The year was the eighth mildest and tenth wettest on record.   Eight of 2021's months were warmer than average, led by December (+4.7°, third mildest) and October (+4.1°, sixth mildest).  These months book-ended the most below average month of the year, November (-1.8°). 

 

Although the year's nearly 60 inches of precipitation was 10 inches above average, seven of the months had below average rainfall.  More than half of the year's precipitation (52%) was in July, August, and September.  And nearly half of the rain in those three months came from tropical systems Henri (8.19") and Ida (7.13").  Here are other highlights of 2021:

 

• A snowstorm that began Jan. 31 and continued into Feb. 2 dumped 17.4”.  Most of the accumulation, 16.8", fell in less than 24 hours (Sunday night, Jan. 31 thru late afternoon on Monday, Feb. 1).  After this snow event, an additional 10" of snow fell during the rest of the month, bring February's total to 26.0", making it the 8th snowiest February on record.

• March had its first temperature in the 80s since 1998, occurring on 3/26 (82°).

• In addition to the excessively wet months of July-Aug-Sept, there were also periods of very low humidity during the year.  For example, nearly half of the days in March had low humidity (below 25%); extremely low humidity was reported on April 6 (7%); and December had it lowest humidity on record on 12/17 (14%).

• The coolest Memorial Day weekend on record (average high/low of 57°/48°) was followed by the ninth warmest June.  A high of 98° on 6/30 was NYC’s hottest reading in nine years years, and the hottest reading in June since another reading of 98° in June 1994.  But just three days later, July had its first reading in the 50s since 2009, and its coolest high temperature (66°) since 2005.

• July, August, and September each had more than 10 inches of rain (July's amount was above 11") – not only the first time in nine years any month had that much rain, but the first time ever that three consecutive months had this much.  This was also the first year to have two rainstorms that produced seven inches+.  They were associated with downgraded hurricanes Henri and Ida , and they were less than two weeks apart (Aug. 21-23 and Sept. 1).

• On the night of  9/1, Ida's rain poured down in just five hours time (and 3.13" in one hour).  More rain fell between 9-10 PM than fell in all of November and December.

As an aside, this one-hour amount was trumpeted by the National Weather Service as being Central Park's greatest one-hour amount on record - but this claim was in error, as NWS's own records show a greater 60-minute amount on Sept. 5, 1913, when 3.31" of rain was measured between midnight and 1 AM - 0.18" more than Ida's 60-minute gully washer.  (11 days earlier, a one-hour amount of 1.94" during Henri also had the NWS claiming it was an all-time record, which was even more in error, as there have been at least a dozen instances of greater amounts in an hour, most recently in July 2018.)

• October had a record streak of lows in the 60s - thirteen days in a row.  It also set a record (for any month) of days with high/lows stuck in the 60s.  There were six such days, concentrated in the nine-day period between Oct. 3-11.  Finally, October's coolest reading of 47° was the mildest reading to have this distinction.

• The final week of October was the rainiest on record (4.71" fell).  That week accounted for more than half of the precipitation measured from October thru December.  This rainy week was followed by the driest November-December on record.  These two dry months prevented the year from reaching the sixty-inch mark in precipitation, coming in at 59.73".  After 31.44" fell in July-September (32.09", if rain on 6/30 is included), 12 of the 13 weeks in October-December had less than 1/10 of that amount (3.06").
