Fall will start with a wild weather pattern across the U.S. with warmth hanging on in the East and fall-like and even wintry weather for parts of the Midwest.
The official start of fall is on Saturday, Sept. 22, 2012, at 10:49 a.m. EDT.
Warmth with highs in the 80s will be in place for the I-95 corridor on Saturday, from New York City to Philadelphia and Washington, D.C., ahead of a cold front. The forecast highs will be closer to normal high temperatures for late-August.
Showers and thunderstorms spreading across the interior Northeast throughout the day will reach the I-95 corridor by the evening hours.
Meanwhile, on the colder, northwestern side of the storm, chilly winds and showers will dampen the Great Lakes region. Highs will reach only the middle to upper 50s for Green Bay, Madison, Milwaukee and Chicago, which are more on par with normal highs for the middle and latter part of October.
With the gusty winds factored in, AccuWeather RealFeel® temperatures will be held in the 40s for much of the day.
Along the northern edge of the storm track, it may even get cold enough for snow to fall across a small swath of the Midwest, from northeastern Minnesota into northwestern Wisconsin.
