NATIONAL WEATHER SERVICE MARQUETTE MI
945 AM EST SUN FEB 18 2012

...WARM WITH BELOW NORMAL SNOW THE FIRST HALF OF THE WINTER SEASON...

A PREVAILING WEST-TO-EAST FLOW OF RELATIVELY MILD PACIFIC AIR HAS
DOMINATED THE WEATHER ACROSS THE UPPER GREAT LAKES FROM OCTOBER INTO 
FEBRUARY. IN FACT...THE OCTOBER 2011 THROUGH JANUARY 2012 MEAN 
TEMPERATURE AVERAGED 3 TO 5 DEGREES ABOVE NORMAL. THIS 4-MONTH 
STRETCH IS NOW AMONG THE TOP TEN WARMEST OCTOBER THROUGH JANUARY 
PERIODS ON RECORD AT MOST PLACES IN WEST AND CENTRAL UPPER MICHIGAN.

SINCE THIS ZONAL FLOW HAS LIMITED THE NUMBER OF ARCTIC AIR 
INVASIONS...LAKE EFFECT SNOW HAS ALSO BEEN BELOW AVERAGE. AT 
MARQUETTE...THE 31.1 INCHES OF SNOW THAT ACCUMULATED THIS PAST 
OCTOBER THROUGH JANUARY IS THE FIFTH LOWEST FOR THAT PERIOD SINCE 
1885. SEASONAL SNOWFALL THROUGH JANUARY IS ALSO WELL BELOW NORMAL AT 
ALL OTHER LOCATIONS.
