Similar to the southern U.S., unusually mild and humid air will sweep into the lower Great Lakes and Ohio Valley tomorrow and tomorrow night setting the stage for heavy rain and severe thunderstorms, some with twisters.
The threat of severe weather will encompass Ohio, southern Indiana, southern Illinois, southeastern Missouri and Kentucky. Residents of those areas should monitor weather conditions closely tomorrow.
The heaviest rains and concomitant risk of flooding will focus on Missouri, Illinois, Indiana and Ohio.
Elsewhere, accumulating snow--a few inches--will coat portions of eastern Nebraska and Kansas.
Tomorrow night, a swath of heavier snow may develop across northern Missouri, southeastern Iowa, northern Illinois and southern Wisconsin.
High temperatures tomorrow are expected to range from slightly below zero in a small area of northeast North Dakota to the 70s in eastern Kentucky.

Locally heavy rain accompanied by a few thunderstorms is expected to soak portions of New York state, Pennsylvania, and New England tomorrow. But little, if any, precipitation is likely south of the Mason-Dixon Line.
In northern New England, the precipitation may begin as a wintry mix of snow, sleet, and freezing rain then gradually change to rain, except in far northern Maine where it may persist as all snow.
High temperatures will be noticeably above early February means, ranging from near 30 at the northern tip of Maine to the 70s in southeast Virginia and southwest West Virginia.

As snowfall winds down in Colorado and northern New Mexico tomorrow, much of the West will catch a breather.
But for the Pacific Northwest, today's brief respite in the recent storminess will come to a quick end. Heavy snow will sweep back into the Cascades and Olympics and reach the Bitterroots by late afternoon.
Rainy, windy conditions will whip areas west of the Cascades where snow levels early in the day will be near 4000 feet, then plunge to 2000 feet or less by late in the day in western Washington and northwest Oregon. East of the Cascades, snow levels may rise briefly to 2000 to 3000 feet.
Overall, high temperatures will range from the teens in the Rockies and northeast Montana to the 60s in Southern California and southwest Arizona.
