=====================================================================
...NOVEMBER 2012 DRY AND SEASONAL, BUT SNOWFALL STILL NEAR NORMAL...
...2012 IN THE DETROIT AREA CHALLENGING FOR THE WARMEST ON RECORD...

AS THE COOL WEATHER FROM OCTOBER CONTINUED INTO EARLY NOVEMBER, A
TEMPORARY CHANGE IN THE PATTERN ALLOWED TEMPERATURES TO CONTINUE
HOVERING ON THE COOL SIDE OF NORMAL BUT CONFINED NEARLY ALL
MEANINGFUL PRECIPITATION TO THE PACIFIC NORTHWEST. THE RESULT WAS
THAT ALL THREE CLIMATE SITES AVERAGED NEAR TO SLIGHTLY ABOVE AVERAGE
DAYTIME HIGHS AND NIGHTTIME LOWS A DEGREE OR TWO BELOW AVERAGE. THE
AVERAGE TEMPERATURE FOR THE MONTH IN DETROIT WAS JUST SLIGHTLY BELOW
AVERAGE AT 40.4 DEGREES, -1.1 DEGREES BELOW THE 41.5 DEGREE MONTHLY
AVERAGE.

PRECIPITATION, ON THE OTHER HAND, WAS LACKING AS MOST OF THE UNITED
STATES ROUNDED OUT THE MONTH WITH WELL UNDER 50 PERCENT OF THEIR
NORMAL MONTHLY VALUES FOR THE MONTH. IN DETROIT, THE PRECIPITATION
TOTAL OF 0.72" WAS 26% OF THE NORMAL MONTHLY VALUE OF 2.29", MAKING
IT THE 6TH DRIEST NOVEMBER ON RECORD. DESPITE THE LACK OF A MORE
TYPICAL AND ACTIVE NOVEMBER PATTERN, ENOUGH OF THAT PRECIPITATION
STILL FELL AS SNOW ON THE 23RD AND 25TH OF THE MONTH TO ACCUMULATE A
TOTAL OF 0.4", WHICH FALLS WITHIN THE NORMAL RANGE FOR NOVEMBER AND
RANKS IT AS ONLY THE 36TH LEAST SNOWY NOVEMBER IN THE HISTORICAL
RECORD. THE DETROIT AREA AVERAGES ONLY 1.5" OF SNOWFALL IN NOVEMBER.
IN FACT, 20 PAST NOVEMBERS HAVE RECORDED NO MEASURABLE SNOWFALL.

THE AVERAGE HIGH TEMPERATURE FOR THE DETROIT AREA IN NOVEMBER WAS
48.8 DEGREES, EQUIVALENT TO THE NORMAL VALUE AND THE 43RD WARMEST ON
RECORD. THE AVERAGE LOW FOR THE MONTH WAS 31.9, -2.4 DEGREES BELOW
THE 34.3 DEGREE NORMAL AND THE 44TH COLDEST ON RECORD. THE AVERAGE
OVERALL TEMPERATURE WAS 40.4, A DEPARTURE OF -1.1 DEGREES BELOW THE
41.5 DEGREE NORMAL AND THE 65TH WARMEST ON RECORD.

DESPITE THE RETURN TO MORE CLIMATOLOGICALLY NORMAL CONDITIONS IN
RECENT MONTHS, THE DETROIT AREA`S AVERAGE TEMPERATURE OF 55.6 FOR
2012 TO-DATE (JAN 1 - NOV 30) IS STILL OUTPACING 1998 AS THE WARMEST
YEAR IN THE HISTORICAL RECORD BY +0.4 DEGREES. AT THE SAME TIME IN
1998, THE AVERAGE TEMPERATURE FOR THE YEAR BY NOVEMBER 30TH WAS 55.2
DEGREES. 2012 SAW MILD WINTER TEMPERATURES TO BEGIN THE YEAR, AN
UNPRECEDENTED MARCH HEATWAVE THAT SENT TEMPERATURES SOARING INTO THE
UPPER 80S WHILE THE MONTH FINISHED +13.5 DEGREES ABOVE NORMAL, AS
WELL AS ONE OF SOUTHEAST MICHIGAN`S HOTTEST SUMMERS ON RECORD.
