Weather Underground Forecast for Thursday, January 31, 2013. An intense storm will continue moving through the eastern third of the country Thursday, finally moving off the eastern seaboard after several days of intense wind, severe thunderstorms, and tornadoes from the Plains through the East Coast. The strongest rain and thunderstorms will form in the morning before the main cold front slides into the Atlantic Ocean. Some of these thunderstorms could produce severe conditions, including large hail, damaging wind, and even the potential of tornadoes. The best chance for severe weather will be along the Southeast Coast in the early morning hours.
In addition to the severe weather aspect of the storm, cold air in the north will allow widespread snow to fall from the Great Lakes region through the Northeast. Another round of lake effect snow is set for the eastern shores of Lake Erie and Lake Ontario as up to 6 inches of new snow will fall on areas already hit by a significant lake effect snow event last week.
In all, the aforementioned storm will be quite significant, with many weather effects including, severe thunderstorms, intense wind, tornadoes, snow, and rain. Residents along the eastern seaboard should continue to brace for the impact of this storm.
Cold temperatures will continue in the Northern Plains where high temperatures will struggle to reach 0 degrees. In fact, most of North Dakota and adjacent areas of South Dakota will remain below 0 degrees, while frigid temperatures in the single digits will expand into Montana and through Wisconsin.
Meanwhile, Pacific moisture will stream into the Northwest, bringing rain and high elevation snow from Washington through Montana. Snow is likely through Montana due to the cold air already over the state.
Temperatures in the Lower 48 states Wednesday have ranged from a morning low of -18 degrees at Crosby, N.D. to a high of 86 degrees at Plant City, Fla.
