SEPTEMBER AND OCTOBER BOTH RANKED AS THE TOP-TEN WARMEST. NOVEMBER
WAS NEAR-NORMAL. THEREFORE, FALL ITSELF RANKS AS THE 9TH WARMEST
FALL ON RECORD. THE AVERAGE TEMPERATURE OF 56.0 DEGREES IS 4.2
DEGREES ABOVE NORMAL AND RANKS AS THE 9TH WARMEST FALL ON RECORD.
THIS IS THE WARMEST FALL SINCE 2016 (56.5 DEGREES).

SEPTEMBER AND NOVEMBER WERE DRIER THAN NORMAL, WHILE OCTOBER WAS
OVER TWO INCHES ABOVE NORMAL. OVERALL, FALL PRECIPITATION WAS A BIT
OF A DRAW, SO TO SPEAK. PRECIPITATION TOTALED 9.78 INCHES, ONLY 0.21
INCHES BELOW NORMAL. THIS RANKS AS THE 53RD WETTEST FALL ON RECORD.
THIS IS THE WETTEST FALL SINCE 2019 (13.15 INCHES).

TOTAL SNOW THIS FALL WAS 1.8 INCHES, 3.5 INCHES BELOW THE NORMAL OF
5.3 INCHES. THIS RANKS AS THE 33RD LEAST ON RECORD.

A MONTH BY MONTH SUMMARY IS BELOW.

SEPTEMBER 2021
...WARMEST SEPTEMBER IN 88 YEARS...

PLENTY OF WARM AFTERNOONS WERE OBSERVED THIS MONTH, INCLUDING THREE
DAYS WHERE THE HIGH REACHED 90 DEGREES OR WARMER. SEPTEMBER HAS
FEATURED THREE OR MORE 90-DEGREE DAYS SEVEN TIMES IN LAST 21 YEARS.
OUR ANNUAL TOTAL IS NOW UP TO FOURTEEN 90-DEGREE DAYS. THE AVERAGE
DAILY TEMPERATURE WAS AT OR BELOW NORMAL ON ONLY SEVEN DAYS THIS
MONTH. AS A RESULT, THE AVERAGE TEMPERATURE FOR THE MONTH WAS 69.2
DEGREES WHICH IS 5.3 DEGREES ABOVE NORMAL. THIS RANKS AS THE 7TH
WARMEST SEPTEMBER ON RECORD.

THERE WERE A FEW EPISODES OF RAIN, THE BULK OF WHICH OCCURRED FROM
THE 20TH THROUGH 23RD WHEN A SLOW-MOVING LOW PRESSURE SYSTEM MOVED
THROUGH. NORTHEAST INDIANA AND NORTHWEST OHIO WERE ABSOLUTELY
DRENCHED BY THIS SYSTEM; RAIN TOTALS IN EXCESS OF 5 INCHES WERE
REPORTED. THAT WAS NOT QUITE THE STORY AT SOUTH BEND WHERE THE TOTAL
FOR THE MONTH WAS 1.96 INCHES, WHICH IS 1.42 INCHES BELOW NORMAL.
THIS RANKS AS THE 35TH DRIEST ON RECORD. THIS DEFICIT PRACTICALLY
"ERASES" THE SURPLUS OF 1.49 INCHES AT THE END OF AUGUST.

OCTOBER 2021
...TOP TEN WARMEST AND WETTEST...

THIS WAS A REMARKABLE MONTH WITH RECORD-WARMTH THROUGH THE 21ST AND
RELENTLESS RAIN. SOUTH BEND EXPERIENCED ITS WARMEST OCTOBER ON
RECORD THROUGH OCTOBER 21ST WITH AN AVERAGE TEMPERATURE OF 64.6
DEGREES. BY THE 22ND, OCTOBER 1920 SURPASSED THIS YEAR`S WARMTH WITH
AN AVERAGE TEMPERATURE OF 64.3 (VS 63.6 OCTOBER 2021). WITHIN THIS
STRETCH OF WARMTH, THREE RECORDS WERE TIED OR BROKEN:

ON 10/7: THE RECORD WARMEST LOW WAS TIED (66 IN 2007)
ON THE 10/10: A NEW RECORD WARMEST LOW OF 70 (PREVIOUS 66 IN 1904)
ON 10/11: THE RECORD WARMEST LOW WAS TIED (64 IN 1920)

A SEASONABLE CHILL FINALLY ARRIVED TO THE AREA ON THE 22ND WHEN THE
AVERAGE DAILY TEMPERATURE WAS SIX DEGREES BELOW NORMAL. THE FINAL
TEN DAYS OF THE MONTH ALSO FEATURED THE FIRST 32-DEGREE FROST WITH A
MORNING LOW OF 31 ON THE 27TH. THE AVERAGE TEMPERATURE FOR THE MONTH
WAS 58.9 DEGREES WHICH IS 6.9 DEGREES ABOVE NORMAL. THIS RANKS AS
THE 8TH WARMEST OCTOBER ON RECORD.

A PROGRESSIVE WEATHER PATTERN BROUGHT SEVERAL ROUNDS OF RAIN TO THE
AREA TO START THE MONTH. THERE WAS A BRIEF DRY PERIOD FROM THE 16TH
TO 19TH BEFORE A SOAKING ROUND OF RAIN ARRIVED. THESE FREQUENT RAIN
EVENTS HAMPERED FALL HARVEST, ESPECIALLY BY THE END OF THE MONTH
WHEN SOILS WERE SATURATED BY 1.60 INCHES ON THE 24TH AND 1.12 INCHES
ON THE 25TH. EIGHTEEN DAYS THIS MONTH FEATURED MEASURABLE
PRECIPITATION; TIED FOR THE 4TH MOST ON RECORD (22 DAYS IN 1898 IS
THE RECORD). THIS IS THE MOST SINCE 2012 WHEN THERE WERE 20 DAYS
WITH MEASURABLE PRECIPITATION.

ALL TOLD, PRECIPITATION TOTALED 6.03 INCHES AND RANKS AS THE 9TH
WETTEST ON RECORD. THIS IS 2.31 INCHES ABOVE NORMAL. THIS IS THE
WETTEST OCTOBER SINCE 9.13 INCHES IN 2017. ONE DAILY PRECIPITATION
RECORDS WAS SET THIS MONTH: 1.60 INCHES ON THE 24TH BROKE THE
PREVIOUS RECORD OF 1.04 IN 2008.

NO SNOW WAS REPORTED THIS MONTH WHICH IS BELOW THE NORMAL OF 0.2
INCH.

NOVEMBER 2021
...TEMPERAUTE SWINGS AND BELOW NORMAL TEMPERATURES...

THIS MONTH FEATURED A NUMBER OF TEMPERATURE SWINGS THAT RESULTED IN
AN AVERAGE MONTHLY TEMPERATURE NEAR NORMAL: 39.9 DEGREES. THIS IS
ONLY 0.1 DEGREES ABOVE NORMAL. THE FIRST SIX DAYS OF THE MONTH WERE
SEASONABLY CHILLY, BUT AFTERNOON HIGH TEMPERATURES ROCKETED INTO THE
60S ON THE 7TH AND 8TH. A COOL-DOWN FOLLOWED UNTIL ANOTHER AFTERNOON
HIGH IN THE 60S OCCURRED ON THE 17TH.

THIS FIRST SNOW OF THIS UPCOMING WINTER SEASON WAS REPORTED ON THE
2ND (TRACE) AND THE FIRST MEASURABLE SNOW OCCURRED ON THE 14TH WHEN
1.2 INCHES OF SNOW WAS OBSERVED. THIS DATE IS NEAR-NORMAL FOR THE
FIRST 1-INCH SNOWFALL. THE MONTH`S TOTAL SNOW WAS 1.8 INCHES WHICH
IS 3.3 INCHES BELOW NORMAL. THIS RANKS AS THE 35TH LEAST SNOWIEST ON
RECORD.

PRECIPITATION FOR THE MONTH TOTALED 1.79 INCHES WHICH IS 0.99 INCHES
BELOW NORMAL. THIS RANKS AS THE 23RD DRIEST ON RECORD.

NO RECORDS WERE SET THIS MONTH.
