The nation's weather

A cold front will move up the East Coast by Wednesday morning and bring light to moderate rain across the eastern states.

Steady rain in the Northeast will increase flood threat for Upstate New York and New England through Thursday. Moreover, some wet snow is possible for the higher elevations Wednesday night into Thursday over northern New England. Lingering rain and showers are likely over the eastern Ohio Valley and central Appalachians Wednesday morning. The front is expected to move off the mid-Atlantic Coast by midday, while the southern portion of the front will become nearly stationary across central Florida. As a result, rain should be diminishing over the Mid-Atlantic Coast Wednesday morning, but showers and thunderstorms will continue over the Florida Peninsula, with possible severe weather Wednesday afternoon.

In the mid-section of the nation, a cold front will advance eastward into the northern and central Plains, producing light to moderate rain with high elevation snow Wednesday morning over the high Plains. Precipitation will increase in coverage and intensity Wednesday evening and Thursday morning as the front moves through the Upper Midwest.

Out West, high pressure will build across the West on Wednesday, bringing fair skies along with mild to warm temperatures. This will be short-lived as a Pacific system arrives early Thursday.

Temperatures in the Lower 48 states Tuesday ranged from a morning low of 10 degrees at Leadville, Colo., to a high of 93 degrees at Carlsbad, Calif.
