A SERIES OF ARCTIC COLD FRONTS PROMOTED WELL BELOW-NORMAL
TEMPERATURES AT TIMES THIS MONTH. THERE WERE THREE DISTINCT PERIODS
OF BELOW-NORMAL TEMPERATURES, WITH THE COLDEST OCCURRING FROM THE
19TH THROUGH 24TH WHEN DAILY AVERAGE TEMPERATURES WERE AS MUCH AS 22
DEGREES BELOW NORMAL. THROUGH JANUARY 15TH, THE AVERAGE DAILY
TEMPERATURE OF 22.5 DEGREES RIVALS THAT OF 2022 (22.6 DEGREES) BUT
WAS OTHERWISE THE COLDEST START TO JANUARY SINCE 17.1 DEGREES IN
2018. THE MORNING LOW OF -5 ON THE MORNING OF THE 21ST WAS THE
COLDEST TEMPERATURE OF THE MONTH. THERE WERE THREE DAYS THIS MONTH
WITH A TEMPERATURE BELOW ZERO, COMPARED TO FIVE DAYS IN JANUARY
2024. IN CONTRAST, A RIDGE DEVELOPED OVER THE EASTERN US IN THE
FINAL DAYS OF JANUARY RESULTING IN A HIGH TEMPERATURE OF 45 ON THE
28TH. THIS IS THE WARMEST HIGH TEMPERATURE FOR JANUARY SINCE 60
DEGREES IN JANUARY 2023. ALL TOLD, THE MONTH`S AVERAGE TEMPERATURE
WAS 22.8 DEGREES AND RANKS AS THE 44TH COLDEST ON RECORD.
LAKE EFFECT SNOW WAS COMMON IN THE WAKE OF THESE ARCTIC COLD FRONTS.
THE GREATEST SINGLE-DAY TOTAL WAS 3.5 INCHES ON THE 23RD. THE
MONTH`S TOTAL OF 14.0 INCHES IS 7.6 INCHES BELOW NORMAL AND RANKS
WITHIN THE MIDDLE-THIRD OF THE 128-YEAR RECORD.
A SLOW-MOVING AREA OF LOW PRESSURE BROUGHT SOAKING RAIN TO PARTS OF
ILLINOIS AND FAR NORTHERN INDIANA TO END THE MONTH. PRECIPITATION
(RAIN AND MELTED SNOW) TOTALED 1.58 INCHES FOR THE MONTH. THIS WAS
1.08 INCHES BELOW NORMAL AND TIES AS THE 38TH LEAST AMOUNT OF
PRECIPITATION ON RECORD (1989).
NO RECORDS WERE SET THIS MONTH.
