FALL 2022

WORSENING DROUGHT CONDITIONS IMPACTED THE REGION DURING AUTUMN 2022.
ON AUGUST 30TH, THE US DROUGHT MONITOR INDICATED "ABNORMALLY DRY"
CONDITIONS WERE PRESENT OVER MUCH OF NORTHERN INDIANA AND SLIVER OF
EXTREME SOUTHERN MICHIGAN. BY OCTOBER 25TH, AN EXPANSIVE AREA OF
"MODERATE DROUGHT" EMERGED ALONG THE US 30 CORRIDOR. THIS LINGERED
THROUGH MOST OF NOVEMBER UNTIL A PERIOD OF LAKE EFFECT SNOW IMPROVED
THE DROUGHT CONDITIONS IN THE IMMEDIATE SOUTH BEND AREA. THEN,
SOAKING RAIN ARRIVED OVER THE FINAL NOVEMBER WEEKEND ACROSS THE
STATE. DURING THIS DRY PERIOD, NUMEROUS FIELD FIRES WERE REPORTED IN
PART DUE TO FALL HARVEST ACTIVITIES. FIRES ASIDE, IMPACTS TO CROPS
WERE GENERALLY MINOR TO NON-EXISTENT.

ALL TOLD, PRECIPITATION TOTALED 9.67 INCHES WHICH IS ONLY 0.32
INCHES BELOW NORMAL. THIS WAS NEAR LAST FALL`S TOTAL IF 9.78 INCHES.

THERE WERE SOME NOTABLE TEMPERATURE SWINGS IN OCTOBER AND NOVEMBER.
DETAILS CAN BE FOUND BELOW IN THE MONTH-BY-MONTH SUMMARIES. OVERALL,
THE AVERAGE TEMPERATURE THIS FALL WAS 53.8 DEGREES; 2.0 DEGREES
ABOVE NORMAL. THIS RANKS AS THE 41ST WARMEST ON RECORD.

THIS FALL`S SNOW TOTAL OF 30.2 INCHES WHICH IS 24.9 INCHES ABOVE
NORMAL. THIS RANKS AS THE 2ND GREATEST SNOW TOTAL ON RECORD BEHIND
FALL OF 1977.

SEPTEMBER 2022.

SEPTEMBER WAS MILD, FEATURING TWO EPISODES WHERE TEMPERATURES IN THE
80S WERE COMMON. ONE OF THESE MILD PERIODS FEATURED SEVERE
THUNDERSTORMS IN THE REGION. FALL-LIKE TEMPERATURES SETTLED IN FOR
THE LAST  WEEK OF THE MONTH WHERE HIGHS IN THE 60S WERE COMMON WITH
LOWS IN THE 40S. THE COLDEST LOW OF THE MONTH WAS 37 DEGREES ON THE
29TH. THERE WAS SOME PATCHY FROST IN OUTLYING AREAS. THE AVERAGE
TEMPERATURE FOR THE MONTH WAS 65.6 DEGREES WHICH RANKS AS THE 46TH
WARMEST ON RECORD.

ABNORMALLY DRY CONDITIONS PREVAILED THIS MONTH IN NORTHWEST INDIANA,
ACCORDING TO THE US DROUGHT MONITOR. AUGUST PRECIPITATION ENDED 1.98
INCHES BELOW NORMAL, AND NOW SEPTEMBER ENDED 1.08 INCHES BELOW
NORMAL. THIS RANKS AS THE 44TH DRIEST ON RECORD.

NO RECORDS WERE SET THIS MONTH.

OCTOBER 2022
DROUGHT CONDITIONS WORSEN, BUT LATE MONTH RAIN PROVIDES SOME RELIEF.

OCTOBER FEATURED SEVERAL BEAUTIFUL AFTERNOONS PRECEDED BY CHILLY AND
SOMETIMES FROSTY MORNINGS. THE FIRST 20 DAYS OF THE MONTH FREQUENTLY
RECORDED A DAILY TEMPERATURE ANOMALY BELOW NORMAL. THE AVERAGE
TEMPERATURE FOR OCTOBER 1-20 WAS 50.9 DEGREES; THE 18TH COLDEST
(TIE) ON RECORD AND THE COLDEST FOR THIS STRETCH SINCE 2012 (50.9
DEGREES AS WELL). ONE RECORD WAS TIED DURING THAT PERIOD. THE HIGH
TEMPERATURE OF 43 ON THE 17TH TIED THE COLDEST HIGH TEMPERATURE SET
WAY BACK IN 1896.

THE FINAL 10 DAYS OF THE MONTH WERE A DIFFERENT STORY, WITH AN
AVERAGE TEMPERATURE OF 56.5 DEGREES RANKING AS THE 14TH WARMEST ON
RECORD. IT WAS THE WARMEST AVERAGE TEMPERATURE FOR THAT PERIOD SINCE
57.8 DEGREES IN 2000. OVERALL, THE AVERAGE TEMPERATURE FOR THE MONTH
WAS 52.9 DEGREES WHICH IS 0.9 DEGREES ABOVE NORMAL.

OCTOBER 17TH WAS WHEN THE FIRST SNOWFLAKES WERE OBSERVED THIS FALL.
THIS OCCURRED AS A STRONG LAKE EFFECT SNOW BAND MOVED INLAND,
DUMPING 1 TO 3 INCHES OF SNOW OVER ALLEN (IN), ELKHART, KOSCIUSKO,
NOBLE, AND WHITLEY COUNTIES. ONLY A TRACE OF SNOW OCCURRED AT SOUTH
BEND. AS SUCH, SOUTH BEND STILL AWAITS ITS FIRST "MEASUREABLE"
SNOWFALL OF THE SEASON WHICH TYPICALLY OCCURS NEAR NOVEMBER 8TH.

DROUGHT WORSENED THROUGH OCTOBER IN MICHIANA. THE FIRST 15 DAYS OF
THE MONTH (0.57") WAS THE DRIEST START TO OCTOBER SINCE 2015
(0.12"). A SOAKING RAIN ARRIVED TO SOUTH BEND IN THE DAYS THAT
FOLLOWED, BUT LOCATIONS SOUTH OF HERE MISSED OUT. AS A RESULT, WHEN
THE OCTOBER 18TH EDITION OF THE U.S. DROUGHT MONITOR WAS RELEASED,
NORTHWEST INDIANA WAS DEEMED TO BE EXPERIENCING "MODERATE DROUGHT"
CONDITIONS. THIS AREA OF MODERATE DROUGHT EXPANDED SOUTHEAST THROUGH
THE STATE THE FOLLOWING WEEK.

BY THE END OF THE MONTH, SOUTH BEND RECEIVED ADDITIONAL RAIN AND THE
MONTHLY TOTAL WAS A HEALTHY 3.85 INCHES WHICH IS ACTUALLY 0.13
INCHES ABOVE NORMAL. THIS RANKS AS THE 41ST WETTEST OCTOBER ON
RECORD. IN THE WEEKS TO COME, IMPROVEMENT OF DROUGHT CONDITIONS ARE
EXPECTED. RECALL THAT OCTOBER 2021 RECORDED A WHOPPING 6.03 INCHES
OF PRECIPITATION WHICH NEGATIVELY IMPACTED FALL HARVEST.

NOVEMBER 2022
A WILD, MEMORABLE MONTH, JUST SHY OF A MONTHLY SNOWFALL RECORD

AFTER A RECORD-WARM START TO THE MONTH (NOVEMBER 1-10 WAS THE 4TH
WARMEST ON RECORD WITH AN AVERAGE TEMPERATURE OF 56.1 DEGREES), A
WINTER CHILL QUICKLY DESCENDED OVER THE REGION. SHORTS AND T-SHIRTS
WERE REPLACED WITH WINTER HATS AND GLOVES AS MORNING LOWS DIPPED TO
12 DEGREES ON THE 20TH. THE GREATEST SINGLE-DAY TEMPERATURE
DEPARTURE BELOW NORMAL WAS 18 DEGREES ON THE 20TH. MEANWHILE, BACK
ON THE 4TH, THE  DAILY TEMPERATURE DEPARTURE WAS 23 DEGREES ABOVE
NORMAL.

THE COLD AIR RUSHING OVER A MILD LAKE MICHIGAN WATER TEMPERATURE
RESULTED IN INTENSE BOUTS OF LAKE EFFECT SNOW. ROUND ONE OCCURRED ON
THE 12TH AND 13TH TOTALING 7.5 INCHES. THE NEXT ROUND OCCURRED OVER
THE COURSE OF FIVE DAYS (16TH-20TH) AS LAKE EFFECT SNOW BANDS
WAVERED OVER THE REGION. THE FIVE-DAY TOTAL WAS A WHOPPING 22.7
INCHES. THIS IS THE GREATEST 5-DAY NOVEMBER TOTAL SINCE 1977.
REGARDLESS OF MONTH, THIS IS THE GREATEST 5-DAY TOTAL SINCE 30.4
INCHES ENDING ON JANUARY 12, 2011.

THE TOTAL SNOW ACCUMULATION THIS MONTH, 30.2 INCHES, IS ONLY ONE-
TENTH OF AN INCH SHY OF THE ALL-TIME NOVEMBER RECORD SET IN 1977.
30.2 INCHES IS A WHOPPING 25.1 INCHES ABOVE NORMAL. TWO DAILY
SNOWFALL RECORD WERE SET: 1) 6.5 INCHES ON THE 18TH BROKE THE
PREVIOUS TOTAL OF 4.0 INCHES SET IN 1989. 2) 9.0 INCHES ON THE 20TH
SHATTERED THE PREVIOUS RECORD OF 5.8 INCHES SET IN 2000.

FOLLOWING THE SNOW AND COLD, A MILD, MORE SEASONABLE AIRMASS
RETURNED. AS A RESULT, NOVEMBER ENDED 3.1 DEGREES ABOVE NORMAL WITH
AN AVERAGE TEMPERATURE OF 42.9 DEGREES. THIS RANKS AS TIED WITH THE
NOVEMBER OF 1948 AND 1978 AS THE 25TH WARMEST NOVEMBER ON RECORD.

DROUGHT CONDITIONS OVER NORTHERN INDIANA WERE NEARLY STEADY THIS
MONTH; "ABNORMALLY DRY" TO "MODERATE DROUGHT" ACCORDING TO THE US
DROUGHT MONITOR. BUT, THE LAKE EFFECT PRECIPITATION DID BEGIN TO
EASE THE DROUGHT STARTING WITH ST. JOSEPH COUNTY. THE TOTAL
PRECIPITATION THIS MONTH WAS 3.41 INCHES WHICH IS 0.63 INCHES ABOVE
NORMAL. THIS RANKS AS THE 37TH WETTEST ON RECORD.

TWO TEMPERATURE RECORDS WERE TIED THIS MONTH, BOTH ON THE 10TH. THE
HIGH OF 75 AND THE LOW OF 55 BOTH TIED A RECORD SET IN 2020.
