the coldest air since April will blast into the Eastern states and will shock parts of the South through the weekend.
In many areas, the cold air will be pushed along and enhanced by gusty winds.
The winds will be generated by a winterlike storm swinging off the mid-Atlantic coast and that will take a curved path back toward New England.
After gusts ranging between 35 and 50 mph swept from the southern Appalachians to the Carolina, Georgia and northeastern Florida coasts on Saturday night, the swath of strong winds will roll across the mid-Atlantic and New England Sunday.
The combination of plunging temperatures, winds and other conditions will produce shockingly low AccuWeather RealFeel® Temperatures. Levels will dip into the teens over the Appalachians and New England to the 20s over the interior South and along the mid-Atlantic coasts and to the lower 30s in part of Florida.
A hard freeze will visit areas from the Ohio Valley to the Appalachians and as far south as the lower Mississippi Valley.
