FEBRUARY 2008...
FEBRUARY OF 2008 WILL BE MOST REMEMBERED FOR BEING THE SNOWIEST ON
RECORD IN PORTIONS OF OUR AREA. TEMPERATURES THROUGH MUCH OF THE
MONTH AVERAGED BELOW NORMAL.
PRECIPITATION WAS OBSERVED ON ALMOST EVERY DAY OF THE MONTH. IN FACT
THERE WERE ONLY 3 DRY DAYS IN GRAND RAPIDS... 2 IN LANSING AND 5 IN
MUSKEGON.
TEMPERATURES GENERALLY AVERAGED AROUND 5 TO 15 DEGREES ABOVE NORMAL
DURING THE FIRST 9 DAYS OF FEBRUARY. HOWEVER THROUGH MOST OF THE
REST OF THE MONTH TEMPERATURES GENERALLY AVERAGED ABOUT 5 TO 15
DEGREES BELOW NORMAL. THE ONLY EXCEPTIONS TO THIS OCCURRED ON THE
17TH AND 25TH... WHEN TEMPERATURES AVERAGED ABOUT 5 TO 10 DEGREES
ABOVE NORMAL.
AT LEAST AN INCH OF SNOW COVER (AND OFTEN MUCH MORE THAN THAT) WAS
REPORTED IN MUSKEGON... GRAND RAPIDS AND LANSING THROUGHOUT THE
ENTIRE MONTH OF FEBRUARY!
FEBRUARY OF 2008 WILL BE MOST REMEMBERED FOR BEING THE SNOWIEST EVER
RECORDED IN GRAND RAPIDS AND LANSING. THE RECORD BREAKING SNOWFALL
OF 41.6 INCHES IN GRAND RAPIDS BROKE THE PREVIOUS RECORD OF 35.5
INCHES SET BACK IN FEBRUARY OF 1900. THE RECORD BREAKING SNOWFALL OF
27.6 INCHES IN LANSING BROKE THE PREVIOUS RECORD OF 25.4 INCHES...
ALSO SET BACK IN FEBRUARY OF 1900.
THE TOTAL SNOWFALL FOR THE MONTH IN MUSKEGON WAS 41.7 INCHES WHICH
WAS THE SECOND SNOWIEST ON RECORD IN MUSKEGON. THE SNOWIEST FEBRUARY
ON RECORD IN MUSKEGON OCCURRED IN 1981... WHEN 45.8 INCHES WAS
RECORDED.
