Today's Weather Outlook

UPDATED By WeatherBug Meteorologist, Andrew Rosenthal
The day after Christmas will bring the entire kitchen sink of weather threats to the eastern half of the U.S., as a major storm system stirs the pot. Severe thunderstorms will pound the Carolinas and Southeast, while wintry weather blankets the Ohio Valley. In between, flooding downpours are possible.
WeatherBug Meteorologist Susie Martin has the latest in her exclusive WeatherBug National Outlook.
Strengthening low pressure will move along the Interstate 95 corridor today, blistering the Carolinas to Florida with an outbreak of powerful thunderstorms. Large hail, damaging winds and tornadoes will all be on the weather radar from Tampa Bay, Fla., to Richmond, Va.
By late-morning, the storm will make its way into the Mid-Atlantic, starting off as a bit of snow and sleet but quickly changing over to a heavy rain-maker. Although the snow might not reach an inch, the rainfall certainly will from Washington, D.C., to Philadelphia.
Along the northern periphery of the storm, heavy snow will fall from southern Illinois into New England. Residents of the Ohio Valley are urged to wait a day to return unwanted Christmas presents, as blizzard conditions will render the roads an impassable mess.
Meanwhile, yet another Pacific storm will continue to spin along the West Coast, sending waves of rain and mountain snow onshore. Showers will pelt Los Angeles and San Francisco, with heavy rain into Seattle, while the Cascades, Sierra, and higher elevations of the Great Basin witness even more snow falling.
In between these storms, pleasant weather will be the name of the game from the Desert Southwest into the Plains. Sunshine will fill the sky in Bismarck, N.D., Albuquerque, N.M., and will help the post-storm cleanup in the Deep South.
Temperatures will be at their warmest ahead of the East Coast storm, with cities from Florida to the Carolinas surging into the 70s. Highs in the 40s and 50s will be found from the coastal Northeast to the Gulf Coast, as well as across the Southwest and California, while chilly 20s and 30s will be found in the mountains and northern New England. The coldest spot in the U.S. will be the northern Plains, where North Dakota and Minnesota will struggle to get out of the single digits and teens.
