...COLDEST START TO DECEMBER IN 14 YEARS GIVES WAY TO MILD MONTH
OVERALL...

WINTER ARRIVED QUICKLY IN THE FORM OF COLDER-THAN-NORMAL
TEMPERATURES TO START THE MONTH. THROUGH DECEMBER 7, THE AVERAGE
TEMPERATURE FOR THE MONTH WAS 8.6 DEGREES BELOW NORMAL (25.5 DEGREES
OBSERVED), GOOD FOR THE COLDEST START TO METEOROLOGICAL WINTER SINCE
24.1 DEGREES IN 2010. MILD LAKE MICHIGAN WATER TEMPERATURES NEAR 40F
WERE CONDUCIVE FOR LAKE EFFECT SNOW WHICH STRETCHED TO FORT WAYNE AT
TIMES. OTHERWISE, COLD FRONTS BROUGHT EPISODIC SNOW SHOWERS. BY
MONTH`S END, 2.3 INCHES OF SNOW WAS RECORDED WHICH IS 5.3 INCHES
BELOW NORMAL AND TIES AS THE 26TH LEAST ON RECORD (1954 AND 1905).

THE AFORMENTIONED COLD WAS NEARLY ERASED IN THE DAYS THAT FOLLOWED
AS HIGH TEMPERATURES SOARED INTO THE MID-40S AND EVEN MID-50S. FIVE
DAYS THIS MONTH REACHED A HIGH OF 50 DEGREES OR WARMER WHICH IS
THREE LESS THAN DECEMBER 2023. ONE MORE BRIEF COLD SNAP OCCURRED
FROM THE 11TH THROUGH 13TH BEFORE A RETURN TO VERY MILD
TEMPERATURES. THE AVERAGE TEMPERATURE FOR THE MONTH WAS 33.6 DEGREES
WHICH IS 2.7 DEGREES ABOVE NORMAL AND RANKS AS THE 25TH WARMEST ON
RECORD.

PRECIPITATION WAS FREQUENT THANKS TO A PROGRESSIVE JET STREAM. THE
US DROUGHT MONITOR WAS GENERALLY UNCHANGED IN OUR AREA THROUGH
DECEMBER WITH ABOUT 34 PERCENT OF THE AREA EXPERIENCING "SEVERE
DROUGHT" (LEVEL 2 OF 4), WHILE ALL OF THE AREA WAS DEEMED AT LEAST
UNDER A "MODERATE DROUGHT" (LEVEL 1 OF 4). THE MONTH RECORDED 3.82
INCHES OF PRECIPITATION WHICH IS 1.35 INCHES ABOVE NORMAL AND IS
19TH WETTEST ON RECORD. 1.77 INCHES OF THIS MONTH`S TOTAL FELL FROM
THE 29TH THROUGH 31ST AS A PAIR OF LOW PRESSURE SYSTEMS BROUGHT
SOAKING RAIN (MIXED WITH A FEW SNOWFLAKES NEW YEAR`S EVE) TO THE
FORT. DATING BACK TO MAY 7TH, FORT WAYNE HAS NOT HAD A DAY WITH 1
INCH OR MORE OF PRECIPITATION.
