Weekend Weather Outlook

A complex weather system will be the cause of numerous weather headaches this weekend as it charts a path from the south-central Plains into the Mid-Atlantic. Snow, ice and even severe storms will be found along its trail.
WeatherBug Meteorologist Addison Green has the latest in his exclusive WeatherBug National Outlook video.
Low pressure will jump onto the southern Texas Plains to start the weekend, bringing heavy snow from eastern Colorado to the Mid-Missouri Valley. A cold rain is expected to fall across Kansas City by late in the afternoon, with heavy rain and fresh thunderstorms blossoming along the Interstate 10 corridor of the Gulf Coast from New Orleans to Tallahassee, Fla. The most powerful thunderstorms will contain all facets of severe weather late this evening and tonight.
Otherwise, generally quiet weather will be found across the West and Southwest, northern Plains, Great Lakes, Mid-Atlantic and Northeast.
The first full weekend of Spring sure won`t feel like it for much of the U.S. Highs will only reach the teens and 20s across the Dakotas and Rockies, with widespread 30s and 40s from Oregon and Washington to the East Coast. The warmer 60s and 70s will be limited to the southernmost reaches of the U.S., with 80s in central and south Texas.
The low pressure will dart into the Ohio Valley on Sunday, with yet another disturbance moving off the Carolinas late on Sunday. Heavy rain will soak the Tennessee Valley and Carolinas, with more than an inch likely in Knoxville, Tenn., and Blacksburg, Va. Snow will be found across the Mid-Mississippi Valley, spreading into the Ohio Valley by evening.
Come Sunday night, the storm will jump off the East coast, allowing for a mixed-bag of snow, sleet and rain to develop across the Mid-Atlantic. While the Appalachians and Interstate 81 corridor will enjoy a fresh March snowfall, the Interstate 95 corridor cities of Baltimore and Washington will see rain mixed with snow.
The only other weather issue will be in the northern Plains, where a disturbance will bring a few snow showers from Colorado to North Dakota. Otherwise, sunshine will dominate the western half of the U.S.
Spring will be nowhere to be found on Sunday. Widespread 20s and 30s will be in place from the Rockies to the interior Northeast. Morning highs in the 40s will trickle back into the 30s in the Mid-Atlantic, with highs in the 40s as far south as the Texas Panhandle and the Carolinas. Much of California will be stuck in the 60s, with 70s and perhaps an 80-degree reading or two in south Texas and Florida.
