THE NOVEMBER OF 2012 WILL MOST LIKELY BE REMEMBERED FOR THE LACK
OF SIGNIFICANT RAINFALL OR SNOWFALL. RAINFALL TOTALS WERE FOR THE
MOST PART IN THE TOP THREE FOR THE DRIEST NOVEMBERS ON RECORD.  TOTAL
RAINFALL WAS UNDER AN INCH AT ALL BUT ONE STATION... SCOTTVILLE
WHICH HAD 1.13 INCHES. MORE THAN HALF...20...OF THE 31 STATIONS WITH
NEARLY ALL THE DATA HAD LESS THAN A HALF INCH OF PRECIPITATION. A
MORE TYPICAL NOVEMBER WOULD BRING AROUND 2.5 INCHES OF
PRECIPITATION.

AT GRAND RAPIDS THERE WERE ONLY 3 DAYS WITH PRECIPITATION AMOUNTS OF
0.01 INCHES OR GREATER... THAT IS THE ALL TIME RECORD LOW FOR
NOVEMBER. THE PREVIOUS RECORD OF ONLY 4 DAYS WAS SET IN 1894.
LANSING HAD 4 DAYS...THAT IS A FOUR WAY TIE FOR THIRD PLACE WITH
THE 2 DAYS IN 1904 BEING THE LEAST.  MUSKEGON HAD 8 DAYS... THAT
PUTS MUSKGEON IN A 11 YEAR TIE FOR 7TH PLACE FOR THE LEAST TOTAL ON
RECORD.

TEMPERATURES IN NOVEMBER 2012 AVERAGED CLOSE TO NORMAL ASIDE FROM
AREAS SOUTH OF INTERSTATE 69...WHERE TEMPERATURES WERE WELL BELOW
NORMAL. THE MONTH STARTED COLDER THAN NORMAL WITH THE 3RD THROUGH
THE 6TH BEING MUCH COLDER THAN NORMAL. FROM THE 9TH THROUGH THE 12TH
TEMPERATURES WERE MUCH ABOVE NORMAL AND IT WAS DURING THIS TIME THAT
THE WARMEST TEMPERATURES OF THE MONTH OCCURED. HIGHS WERE IN THE MID
60S TO NEAR 70 ON THE 11TH. ANOTHER QUICK COOL DOWN FOLLOWED FROM
THE 13TH THROUGH 15TH ONLY TO SEE ANOTHER WARM UP FROM THE 16TH
THROUGH THE 23RD. ONCE AGAIN ANOTHER COLD FRONT CAME THROUGH AND
TEMPERATURES WERE ONCE AGAIN BELOW NORMAL FROM THE 24TH THROUGH THE
28TH. A STRONG PACIFIC STORM BROUGHT WARMER THAN NORMAL TEMPERATURES
BACK TO THE AREA FOR THE 29TH AND 30TH.

THE FREQUENCY OF DAYS WITH LOWS AT OR BELOW FREEZING WAS ABOVE
NORMAL. IN FACT ACROSS THE AREA THE TOTAL NUMBER OF DAYS WITH LOWS
AT OR BELOW FREEZING WERE THE HIGHEST IN MANY YEARS. GRAND RAPIDS
HAD 20 DAYS...THE LAST NOVEMBER WITH A HIGHER TOTAL WAS IN 2002 WITH
22 DAYS.  LANSING HAD 21 DAYS...THE LAST NOVEMBER WITH A HIGHER
TOTAL WAS 1996 WITH 22 DAYS. AT MUSKEGON THERE WERE 19 DAYS...THE
LAST NOVEMBER WITH A HIGHER TOTAL WAS 1997 WITH 20 DAYS.
