NOVEMBER 2014 WAS A REMARKABLE MONTH FOR COLD AND SNOW. TEMPERATURES
ACROSS SOUTHWEST LOWER MICHIGAN AVERAGED OUT WELL BELOW NORMAL...
SNOWFALL ABOVE TO WELL ABOVE NORMAL... AND PRECIPITATION NEAR TO
ABOVE NORMAL. GRAND RAPIDS HAD THEIR SNOWIEST NOVEMBER ON RECORD
WHILE MUSKEGON HAD THEIR SECOND SNOWIEST. A NUMBER OF DAILY
TEMPERATURE... SNOWFALL... AND PRECIPITATION RECORDS WERE ALSO SET.

THE FIRST 11 DAYS OF THE MONTH HAD A MIX OF WEATHER BUT WAS OVERALL
FAIRLY BENIGN. THAT ALL CHANGED AS ARCTIC AIR SPILLED INTO THE
MIDWEST AND GREAT LAKES REGIONS AND STAYED PUT FOR 10 DAYS. FOR
NOVEMBER 12TH THROUGH 21ST... TEMPERATURES RANGED MOSTLY FROM THE
UPPER TEENS TO LOW 30S. ONLY ON A FEW OCCASIONS DID THE HIGH
TEMPERATURES CLIMB INTO THE MID 30S TO MEET THE NORMAL LOW
TEMPERATURE FOR THE TIME OF YEAR. THE MAGNITUDE AND LONGEVITY OF THE
COLD AIR OUTBREAK RIVALED THAT OF FEW NOVEMBERS PAST... 1950 BEING
THE MOST RECENT YEAR THAT COULD CLAIM A MORE SIGNIFICANT PROLONGED
OUTBREAK IN NOVEMBER. GRAND RAPIDS BROKE ONE DAILY LOW TEMPERATURE
RECORD AND ONE DAILY MINIMUM HIGH TEMPERATURE RECORD. MUSKEGON BROKE
ONE DAILY LOW TEMPERATURE RECORD... AND BROKE OR TIED TWO DAILY
MINIMUM HIGH TEMPERATURE RECORDS.

THE COLD AIR AND FAVORABLE ATMOSPHERIC SETUP FOR LAKE EFFECT SNOW
LED TO A PROLONGED AND RECORD-BREAKING EARLY SEASON SNOWFALL ACROSS
MUCH OF THE GREAT LAKES. DUE TO STIFF WIND SPEEDS... THE GREATEST
SNOW AMOUNTS GENERALLY FELL AWAY FROM THE IMMEDIATE LAKESHORE. GRAND
RAPIDS AND MUSKEGON EACH BROKE ONE DAILY SNOWFALL RECORD DURING THIS
PERIOD. THE SNOW THAT FELL DURING THE COLD AIR OUTBREAK IN THE
MIDDLE OF THE MONTH ACCOUNTED FOR THE VAST MAJORITY OF THE MONTHLY
TOTALS. GRAND RAPIDS RECEIVED 31.0 INCHES OF SNOW FOR NOVEMBER...
ECLIPSING THE PREVIOUS RECORD OF 28.2 INCHES IN 1895. MUSKEGON
ACCUMULATED 24.5 INCHES... FALLING SHORT OF THE 1995 RECORD OF 25.7
INCHES. LANSING HAD 6.2 INCHES... STILL ABOVE NORMAL FOR THE MONTH.

THE COLD OUTBREAK ENDED THE 22ND AS TEMPERATURES CLIMBED INTO THE
40S AND THEN 50S AHEAD OF A STRENGTHENING LOW PRESSURE SYSTEM. A
SIGNIFICANT AMOUNT OF RAIN WAS RECEIVED ACROSS THE AREA FROM THE
23RD TO 24TH... TOTALING 1 TO 2 INCHES. GRAND RAPIDS AND MUSKEGON
SET DAILY PRECIPITATION RECORDS ON ONE DAY AND LANSING SET RECORDS
ON TWO DAYS. THE SNOW ON THE GROUND MELTED ENTIRELY DURING THIS
BRIEF WARM SPELL AND CONTRIBUTED TO PUSHING A FEW RIVERS ABOVE
BANKFULL. SEVERAL LOCATIONS IN SOUTHERN LOWER MICHIGAN EXPERIENCED
WIND GUSTS ABOVE 50 MPH ON THE BACKSIDE OF THIS SYSTEM.

COLD AIR AND SNOW RETURNED LATE ON THE 24TH AND STAYED THROUGH THE
28TH. A SIGNIFICANT LAKE EFFECT SNOW BAND IN NORTH-NORTHWEST WINDS
PROVIDED SOME LAKESHORE AREAS WITH 6 TO 10 INCHES OF ACCUMULATION ON
THANKSGIVING. ANOTHER BRIEF TEMPERATURE SWING INTO THE 50S DURING
THE 29TH AND 30TH ENDED THE EVENTFUL MONTH.

GRAND RAPIDS RECEIVED AT LEAST A TRACE OF PRECIPITATION EACH DAY
FROM THE 4TH THROUGH THE 30TH. THIS WAS MOSTLY TRUE AT A NUMBER OF
OTHER SITES WITH THE EXCEPTION OF A DAY OR TWO. DESPITE THE
NEAR-RECORD TO RECORD SNOWFALL AT MUSKEGON AND GRAND RAPIDS...
NOVEMBER DREW TO A CLOSE WITH NO SNOW ON THE GROUND.
