National Weather Service Weather Forecast Office

 

THE CLIMATE PREDICTION CENTER (CPC) IS NOW FORECASTING A BETTER THAN
CLIMATOLOGICAL CHANCE OF A BELOW NORMAL 3-MONTH AVERAGE
TEMPERATURE...BUT ABOVE NORMAL 3-MONTH PRECIPITATION ACROSS ALL OF
UPPER MICHIGAN IN JANUARY THROUGH MARCH 2011. CPC EXPECTS THE LOW
PRESSURE TROUGH OVER SOUTHEAST CANADA THAT IS RESPONSIBLE FOR THE
CHILLY WEATHER IN DECEMBER OVER THE UPPER GREAT LAKES TO LINGER MUCH
OF THE TIME THROUGH THE WINTER...HELD IN PLACE BY AN ANOMALOUSLY
STRONG AND PERSISTENT HIGH PRESSURE RIDGE NEAR GREENLAND. THIS
BLOCKING WEATHER PATTERN WILL ALLOW FREQUENT INVASIONS OF ARCTIC AIR
INTO THE UPPER GREAT LAKES.
