FEBRUARY WAS BOTH COOLER AND WETTER THAN NORMAL FOR SOUTHWEST LOWER
MICHIGAN. THE TWO MOST SIGNIFICANT SNOWSTORMS OCCURRED AT OPPOSITE
ENDS OF THE MONTH.

THE AVERAGE MONTHLY TEMPERATURE FOR FEBRUARY WAS AROUND 24
DEGREES... WHICH IS APPROXIMATELY 2 DEGREES BELOW NORMAL FOR MOST
LOCATIONS. THE FIRST WEEK OF FEBRUARY IN PARTICULAR WAS MUCH COLDER
THAN NORMAL... WITH THE FIRST THREE DAYS OF THE MONTH ALL
EXPERIENCING NEGATIVE DOUBLE DIGIT DEPARTURES FROM NORMAL. THE 7TH
OF THE MONTH WAS THE FIRST DAY TO RECORD A DAILY AVERAGE TEMPERATURE
ABOVE NORMAL. THE SECOND WEEK OF FEBRUARY WAS ACTUALLY WARMER THAN
NORMAL. A DYNAMIC WEATHER PATTERN CONTINUED TO CONTRIBUTE TO
FLUCTUATING BACK AND FORTH BETWEEN COOLER AND WARMER THAN NORMAL
TEMPERATURES WITH EACH LOW PRESSURE SYSTEM.

MANY LOCATIONS RECEIVED ABOVE NORMAL PRECIPITATION FOR FEBRUARY...
WITH A FEW LOCATIONS NEAR NORMAL. THERE WERE NO MORE THAN FIVE
CALENDAR DAYS IN WHICH NO PRECIPITATION FELL. HOWEVER... A LARGE
PORTION OF THE PRECIPITATION IN FEBRUARY FELL DURING THE FIRST
AND LAST WEEKS OF THE MONTH... WITH OFF AND ON LIGHTER PRECIPITATION
DURING THE MIDDLE PORTION OF THE MONTH.

SNOWFALL FOR SOUTHWEST LOWER MICHIGAN WAS ALSO ABOVE NORMAL FOR
FEBRUARY. MONTHLY SNOWFALL DEPARTURES FROM NORMAL TENDED TO DECREASE
WITH INCREASING DISTANCE FROM LAKE MICHIGAN... WHICH IS TYPICAL.
HOWEVER... LANSING STILL RECEIVED ABOVE NORMAL SNOWFALL. MUSKEGON
SET A RECORD FOR MONTHLY MAXIMUM SNOWFALL. MUSKEGON RECEIVED 53.2
INCHES OF SNOW IN FEBRUARY... WHICH BREAKS THE PREVIOUS FEBRUARY
RECORD OF 45.8 INCHES SET IN 1981. A GROUNDHOG DAY STORM PROVIDED
SIGNIFICANT SNOWFALL TOTALS AT THE BEGINNING OF THE MONTH. ON THE
26TH AND 27TH... SOUTHWEST LOWER MICHIGAN RECEIVED A MIX OF RAIN AND
SLEET AS PRECIPITATION MOVED IN FROM SOUTH TO NORTH. IT EVENTUALLY
CHANGED OVER TO ALL SNOW AND PROVIDED 3 TO 7 INCHES AT THE END OF
THE MONTH.
