A vast majority of the central and eastern U.S. will have below normal
temperatures has the Arctic airmass spreads from the Plains into the
Ohio/Tennessee Valley and eastward. Hundreds of locations may set new
records during this time. By Wednesday morning, low temperatures in the
teens and 20s will be common along much of the East Coast, the Ohio
Valley, and down as far south as the upper Texas coast, making it feel
like the middle of winter for these areas. Freeze and Hard Freeze warnings
are in effect from the Texas Coast to coastal South Carolina. Temperatures
will begin to warm up on Thursday once the expansive high pressure system
migrates offshore the New England Coast.
Meanwhile, snow currently falling across portions of the Tennessee Valley,
the Appalachians and the Northeast will begin to taper off this evening-
while the lake effect snow will persist into Wednesday morning. Rain,
spanning from Florida to New England, will continue to track
east-northeast offshore this evening. Additionally, an upper-level
disturbance arriving from northern Mexico will increase the chance of rain
along the Gulf Coast as a coastal front forms just offshore.
Rain and snow chances will increase across the Pacific Northwest and the
Interior as an upper-level disturbance moves inland. Amounts are expected
to be on the lighter side as the system quickly passes through the Plains
Wednesday and into the Great Lakes region by Thursday. For the Great
Basin/Rockies region, warmer and drier conditions are expected to prevail
which will maintain an increased risk for spread of wildfires.
