NOVEMBER 2016 WILL BE REMEMBERED FOR ITS REMARKABLY WARM CONDITIONS.
THE ENTIRE STATE ENDED THE MONTH WELL ABOVE NORMAL IN REGARDS TO MEAN
TEMPERATURE. PRECIPITATION TOTALS RANGED FROM NEAR OR SLIGHTLY BELOW
NORMAL OVER SOUTHERN LOWER MICHIGAN TO MODERATELY BELOW NORMAL
THROUGH CENTRAL AND NORTHERN LOWER MICHIGAN.

NOVEMBER 1ST STARTED THE MONTH OFF OVER 15 DEGREES ABOVE NORMAL WITH
HIGH TEMPERATURES REACHING INTO THE MID AND UPPER 70S OVER INLAND
LOCATIONS OF LOWER MICHIGAN. LAKE SHORE COUNTIES WERE ONLY SLIGHTLY
COOLER WITH HIGHS IN THE MID TO UPPER 60S. MUCH OF THE MONTH WOULD
FOLLOW SUIT WITH THIS WARMER THAN NORMAL THEME. IN FACT, MORE THAN
TWO-THIRDS OF THE DAYS IN NOVEMBER WERE IN THE ABOVE NORMAL
CATEGORY. NEARLY A THIRD OF THE MONTH FEATURED DAILY AVERAGE
TEMPERATURES 10 OR MORE DEGREES ABOVE NORMAL. NOVEMBER 18TH WAS A
RECORD BREAKER WITH A HIGH TEMPERATURE TIED AT GRAND RAPIDS AND SET
AT LANSING. DESPITE ONLY ONE DAY REACHING A RECORD, THE WELL ABOVE
NORMAL FINISH CAN BE ATTRIBUTED TO THE CONSISTENCY OF MILD AIR,
RATHER THAN A SHORTER PERIOD OF EXTREME WARMTH. ONLY A HANDFUL OF
DAYS WERE SLIGHTLY TO MODERATELY BELOW NORMAL. MUCH OF SOUTHWEST
LOWER MICHIGAN FINISHED 5 TO 6 DEGREES ABOVE NORMAL FOR THE MONTH,
RESULTING IN A TOP 4 WARMEST RANKING FOR THE PRIMARY CLIMATE SITES
(GRAND RAPIDS, LANSING AND MUSKEGON).

PRECIPITATION TOTALS WERE MOSTLY BELOW NORMAL, ESPECIALLY NORTH AND
WEST OF THE GRAND RAPIDS METRO AREA. ABOUT THREE-FOURTHS OF THE DAYS
IN THE MONTH, AT EACH OF THE THREE CLIMATE SITES, RECORDED A TRACE
OR LESS OF PRECIPITATION. MUCH OF THE MOISTURE WAS CONVECTIVE IN
NATURE AND WAS RECEIVED WITHIN A FEW HEAVIER EPISODES OF RAINFALL.
ABOUT ONE-THIRD OF THE TOTAL PRECIPITATION RECEIVED AT EACH CLIMATE
SITE WAS RECEIVED IN A SINGLE EVENT. FOR GRAND RAPIDS AND LANSING,
MOST OF THEIR PRECIPITATION FELL ON NOVEMBER 2ND WITH MORE THAN ONE
INCH OF RAIN. MUSKEGON`S HEAVIEST RAIN EVENT CAME ON NOVEMBER 28TH
WITH MORE THAN THREE-QUARTERS OF AN INCH OF RAIN. ALL THREE SITES
WERE WELL BELOW NORMAL IN SNOWFALL. A LINE OF THUNDERSTORMS PRODUCED
50 TO 80 MPH WIND GUSTS IN THE JACKSON AREA ON NOVEMBER 18TH.
MUSKEGON AND GRAND RAPIDS ONLY RECORDED MEASURABLE SNOWFALL OF AN
INCH OR LESS ON NOVEMBER 19TH. SNOW TOTALS WERE A BIT HIGHER IN THE
HIGHLANDS OF CENTRAL TO NORTHERN MICHIGAN AWAY FROM LAKE MICHIGAN,
BUT STILL BELOW NOVEMBER AVERAGE.
