Some of these storms may become strong to severe, with damaging winds and a few tornadoes possible from parts of the Southeast, through the Mid-Atlantic, and into the Hudson Valley.
Behind the front, a series of upper level disturbances, along with cold northwesterly to westerly winds, will support rain and snow showers from the Great Lakes, Ohio Valley, into the Northeast and Mid Atlantic tonight and Friday.
Scattered snow squalls may develop and move over the Great Lakes and Ohio Valley tonight.
Snow squalls are likely during the day on Friday from the central Appalachians and lower Great Lakes into interior portions of the Northeast and Mid Atlantic.
Brief, but intense snowfall within these squalls can rapidly reduce visibility and lead to dangerous driving conditions.
Meanwhile, the front is expected to linger across the Florida Peninsula, supporting additional showers and storms and the potential for isolated strong to severe storms into the weekend.
Farther west, a frontal boundary is expected to bring rain and snow from the Rockies into the north-central Plains tonight into Friday morning, with mostly light accumulations expected.
During the day on Friday, expect rain showers and thunderstorms from the northern Plains to Oklahoma and northern Texas.
While widespread severe weather is not expected, isolated strong to severe storms may occur across parts of Oklahoma and northern Texas.
A few dry thunderstorms may develop, which combined with breezy conditions, may elevate fire weather concerns tomorrow from the Oklahoma and Texas Panhandle region into west-central Texas.
In the West, a frontal boundary is forecast to produce mainly light low elevation rain and mountain snow as it moves from the Pacific Northwest to the northern Rockies late Friday into Saturday.
Elsewhere across the West, expect dry conditions with temperatures climbing above average across most areas by the weekend. ■
