Wintry mix of precipitation possible over the Lower to Middle
Weather will become increasingly active over the Northwest and
After some of the coldest air in recent history spread down over much of the U.S....temperatures will begin to moderate across the eastern two thirds of the Nation as a deep vortex lifts back northward through eastern Canada.
Also...strong and gusty winds should begin to diminish...allowing
intense lake effect snows downwind of Lake Erie and Ontario to gradually relax over the next few days.
Elsewhere east of the Continental Divide...strong surface high pressure expanding over the region will keep the majority of locations precipitation free.
An exception to this will be over the South Central U.S....where return flow from the Gulf of Mexico...combined with weak energy streaking through aloft...will foster increased shower activity over East Texas on Wednesday.
As the warm Gulf air lifts farther northward and overruns a frontal boundary in place...a wintry mix of precipitation will be possible across the Lower to Middle Mississippi Valley...especially over the Ozarks.
A series of weak Pacific systems moving onshore will make for increasingly active weather over the Northwest and Rockies the next few days.
Widespread shower activity is expected with the passage of each system.
