JANUARY 2024
...WETTEST JANUARY IN 11 YEARS;10TH WETTEST JANUARY ON RECORD...

THIS MONTH HAD IT ALL: A RECORD COLD HIGH TEMPERATURE, RECORD DAILY
PRECIPITATION AND SNOWFALL, AND A SIGNIFICANT LAKE EFFECT SNOW EVENT.

THE FIRST 12 DAYS OF JANUARY WERE MILD, WITH AN AVERAGE DAILY
TEMPERATURE AS GREAT AS 11 DEGREES ABOVE NORMAL (JANUARY 9TH). BY
THE END OF THAT PERIOD, THE AVERAGE TEMPERATURE FOR THE MONTH (32.3
DEGREES) WAS 7.3 DEGREES ABOVE NORMAL WHICH RANKS AS THE 25TH
WARMEST ON RECORD. AS THE POLAR VORTEX WEAKENED, COLD AIR BLASTED
INTO THE REGION. FROM THE 13TH THROUGH 21ST, THE AVERAGE DAILY
TEMPERATURE WAS AS MUCH AS 26 DEGREES BELOW NORMAL (JANUARY 15TH).
HIGH TEMPERATURES WERE IN THE SINGLE DIGITS AT TIMES AND OVERNIGHT
LOWS WERE BELOW ZERO. THE COLDEST TEMPERATURE OF THE MONTH, -9 ON
THE 14TH AND 15TH, WAS THE COLDEST TEMPERATURE RECORDED AT SOUTH
BEND SINCE -20 DEGREES ON JANUARY 31, 2019 (NOTE: A LOW OF -8 WAS
RECORDED ON DECEMBER 23, 2022). THIS CHILL WAS SHORT LIVED AS ABOVE-
NORMAL TEMPERATURES RETURNED TO END THE MONTH. THE MONTH ENDED WITH
AN AVERAGE TEMPERATURE OF 26.7 DEGREES WHICH IS 2.6 DEGREES ABOVE
NORMAL. THIS RANKS AS THE 49TH WARMEST JANUARY ON RECORD. RECORDS
BEGAN IN 1893.

ONE TEMPERATURE RECORD WAS SET THIS MONTH. THE HIGH OF 6 DEGREES ON
THE 14TH BROKE THE PREVIOUS DAILY COLDEST HIGH TEMPERATURE RECORD OF
7 DEGREES SET IN 1929.

AS THE ARCTIC AIR ARRIVED AND SUBSEQUENTLY DEPARTED, A COUPLE
EPISODES OF SNOW OCCURRED TOTALING 22.2 INCHES FOR THE MONTH. THIS
IS 0.6 INCHES ABOVE NORMAL AND RANKS AS THE 37TH MOST ON RECORD.
THIS IS NOTABLY MORE THAN THE PALTRY 7.5 INCHES THAT WERE RECORD IN
JANUARY 2023.

SNOW ON THE 9TH WAS NOTABLE BECAUSE A PRECIPITATION RECORD OF 1.03"
OCCURRED THAT DAY PAIRED WITH 2.3 INCHES OF HEAVY WET SNOW. THIS WAS
A RESULT OF RAIN CHANGING TO SNOW. STANDING WATER WAS TRAPPED BENEATH
THIS "CONCRETE SNOW" MAKING FOR SOUPY, SLOPPY CONDITIONS THROUGHOUT
THE REGION. LATER IN THE MONTH, A DOMINANT LAKE EFFECT SNOW BAND
DEVELOPED AND DROPPED NEARLY 3` (UNOFFICIAL MEASUREMENT) OF SNOW IN
THE LAPORTE AND MICHIGAN CITY AREA. THE CO-OP SITE AT LAPORTE HAD A
TWO-DAY TOTAL OF 32.4 INCHES ENDING EARLY IN THE MORNING ON THE 20TH.

AS PART OF THIS LAKE EFFECT SNOW, SOUTH BEND RECORDED A NEW DAILY
SNOWFALL RECORD OF 5.9 INCHES ON THE 19TH. THIS BROKE THE PREVIOUS
DAILY RECORD OF 5.7 INCHES SET IN 2012.

LASTLY, PRECIPITATION FOR THE MONTH TOTALED AN IMPRESSIVE 4.53
INCHES. THIS IS 1.87 INCHES ABOVE NORMAL AND TIES 1916 AS THE 10TH
WETTEST ON RECORD. THIS WAS THE WETTEST JANUARY SINCE 4.82 INCHES IN
JANUARY 2020. FOR PERSPECTIVE, THIS MONTHLY TOTAL IS COMPARABLE TO
THE NORMAL PRECIPITATION AMOUNT FOR MAY: 4.20 INCHES.
