A RELATIVELY COOL AUTUMN WAS FOLLOWED BY AN ABRUPT, BUT BRIEF, RETURN TO MILD WEATHER FOR THE FIRST THREE WEEKS OF DECEMBER. HIGH TEMPERATURES IN THE UPPER 50S AND 60S THROUGH DECEMBER 4TH WERE FOLLOWED BY AN ADDITIONAL TWO WEEKS OF HIGH TEMPERATURES IN THE 40S ON MOST DAYS. THE WARM STRETCH INCLUDED A RECORD HIGH OF 65 DEGREES AT FLINT ON DECEMBER 4TH, WHICH BROKE THE PREVIOUS RECORD OF 64 DEGREES FOR THE DATE. THE RESULT WAS THAT, DESPITE A RETURN TO MORE SEASONAL WEATHER DURING THE LAST SEVERAL DAYS OF THE MONTH, THE AVERAGE MONTHLY TEMPERATURES FOR FLINT (33.5 DEGREES) AND SAGINAW (34.1 DEGREES) WERE T-6TH AND 4TH WARMEST ON RECORD RESPECTIVELY. IN ADDITION, AFTER RECEIVING BELOW NORMAL SNOW BETWEEN THE 1ST AND 18TH DAYS OF THE MONTH, THE FLINT AREA MEASURED A TOTAL OF 8.4" BETWEEN THE 18TH AND THE 31ST, INCLUDING 5.0" ON DECEMBER 26TH-27TH AS A STRONG STORM DELIVERED A GLANCING BLOW. SAGINAW, ON THE OTHER HAND, MEASURED 3.6" ON DECEMBER 8TH-9TH WITH ONLY AN ADDITIONAL 3.8" ACCUMULATING DURING THE REST OF THE MONTH, YIELDING A MONTHLY TOTAL OF 7.4". ALTHOUGH THE AFOREMENTIONED WINTER STORM BROUGHT A WIDESPREAD 5 TO 10 INCH SNOWFALL TO THE REGION, SAGINAW MANAGED ONLY 1.5" ON DECEMBER 26TH AS THEY REMAINED ALONG THE FAR NORTHWEST PERIPHERY OF THE SNOW SHIELD AS IT LIFTED THROUGH SOUTHEAST MICHIGAN. FLINT`S SNOWFALL FOR THE SEASON NOW STANDS AT 11.1", -3.6" BELOW THE 14.7" SEASONAL NORMAL. IN SAGINAW, THE SEASONAL SNOWFALL TOTAL IS NOW 9.8", -3.1" SHY OF THE 12.9" SEASONAL NORMAL. THE AVERAGE HIGH TEMPERATURE FOR THE FLINT AREA WAS 40.5 (7TH WARMEST), AND +6.4 DEGREES ABOVE THE NORMAL VALUE OF 34.1. THE AVERAGE HIGH IN SAGINAW WAS 40.4 (3RD WARMEST ON RECORD), +6.9 DEGREES ABOVE THE 33.5 DEGREE NORMAL. FLINT`S AVERAGE LOW FOR THE MONTH WAS 26.5 (TIED WITH 1952 FOR THE 9TH WARMEST ON RECORD), +5.7 DEGREES ABOVE THE 20.8 DEGREE NORMAL. SIMILARLY, THE AVERAGE LOW IN SAGINAW WAS 27.8 (4TH WARMEST ON RECORD), AND +6.6 ABOVE THE NORMAL OF 21.2 DEGREES. THE AVERAGE TEMPERATURE FOR THE ENTIRE MONTH OF DECEMBER IN FLINT WAS 33.5 (6TH WARMEST), A DEPARTURE OF +6.1 DEGREES FROM THE 27.4 DEGREE DECEMBER NORMAL. FOR SAGINAW, IT WAS 34.1 (4TH WARMEST ON RECORD), AND +6.8 ABOVE THE 27.3 DEGREE DECEMBER NORMAL.
