...WINTER FINALLY SETTLES IN FOR THE LAST 10 DAYS OF DECEMBER...

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. IN ADDITION, THE FLINT AREA`S AVERAGE TEMPERATURE
OF 51.7 FOR THE CALENDAR YEAR WAS ITS WARMEST ON RECORD, ECLIPSING
THE PREVIOUS RECORD OF 51.4F SET IN 1931.
