Powerful Cold Front Hits Midwest Today

A strong clipper system at 991 millibars near International Falls is forecast to move southeastward over the Great Lakes today, deepening over Lake Huron tommorow to 978 mb according to some models. Wind gusts may be as high as 50 mph in the vicinity of such a storm and higher in any thunderstorms that are able to form along the relatively moisture starved cold front. Along with the high winds will be a sharp temperature drop - perhaps 10 degrees in just few hours. Parts of the Upper Midwest, Great Lakes and New England will for the first time this fall have highs only in the 50s over the next several days.
