...Snow is expected to spread quickly from the Central Plains to the
Midwest today, and then across northern New England on Wednesday into
Thursday...
...Subfreezing record cold temperatures expected across much of the
south-central U.S. Wednesday morning, shifting to parts of the eastern
U.S. Thursday morning...
...Threat of heavy rain gradually diminishes across central and southern
Florida over the next couple days...
Snow associated with a late-season upslope snow event over the central
Rockies is now spreading eastward across the Central Plains as a low
pressure wave develops along the sharp cold front. This wave is forecast
to track quickly northeastward to bring mixed rain and snow across the
Midwest today and a round of snow across the Ohio Valley tonight. On
Wednesday, the system is forecast to intensify more rapidly as it moves
across New England. A swath of wet snow is expected to the north of the
storm track with 6 to locally 12 inches possible near the Canadian border.
Mixed wintry precipitation is expected near the storm track while rain
and a few thunderstorms pass to the south.
Unseasonably cold air will be ushered southward behind the intensifying
storm, leading to widespread freeze and frost concerns tonight across the
central/southern Plains the Midwest. Numerous daily record low
temperatures are forecast to be tied or broken on Wednesday morning as
temperatures dip to below freezing, which is about 20 degrees below
average. Hard Freeze Warnings and Watches have been issued from northern
Texas to the lower Great Lakes. The record low temperatures are forecast
to shift into parts of the eastern U.S. by Thursday morning.
Meanwhile, active weather across Florida has been edging very slowly
southward into southern Florida ahead of a slow-moving front. A low
pressure wave forming on the front could bring additional heavy showers
and thunderstorms today across central Florida. Improving conditions
should begin Wednesday morning as the wave moves off into the Atlantic and
rain chances decrease across southern Florida.
