Snow Sweeps Across Central U.S.; Rain Pelts Mid-South
UPDATED 6:45 PM CST, December 31, 2012
By WeatherBug Meteorologist, Chad Merrill
Winter is not letting up on the last day of 2012 across the Central U.S. A weak storm system is producing a stripe of light snow from Nebraska and Kansas to the Ohio Valley. The snow will relinquish its grip on the Plains and Midwest as the calendar flips over to a new year Tuesday.
Moisture sliding north of a low pressure and warm front extending form eastern Texas into the Tennessee Valley is being squeezed out as snow along Interstate 70 from the Plains to the Midwest. Scott City, Kan., has received 7.5 inches with a general swath of 1 to 3 inches from southern Nebraska into central Indiana.
Another 1 to 2 inches will accumulate through Tuesday morning from the Central Plains to the Midwest where Winter Weather Advisories and Winter Storm Warnings continue. Topeka, Kan., Kansas City, Mo., St. Louis and Indianapolis are included. Be sure to allow yourself plenty of time to get to your destination for New Year`s celebrations this evening.
As high pressure nudges into the Plains and Midwest, the snow will end on New Year`s Day. In the warmer air farther south, rain is pelting the Mid-South to the western Gulf Coast. The soggy weather will slide to the Atlantic Coast by late Tuesday as the low pressure swiftly moves east along Interstate 20 tonight and New Year's Day.
One to 2 inches of rain will pelt the western Gulf Coast to the Southeast, including Houston, Shreveport, La., Jackson, Miss., and Birmingham, Ala., tonight into Tuesday. The rain will help chip away at rainfall deficits along the drought-plagued Gulf Coast.
No thunderstorms are expected so the threat for flash flooding from soaking downpours will be minimal.
As the storm motors to the Atlantic Coast, the colder northern fringe in the southern Mid-Atlantic will see a snow and rain mix late Tuesday into early Wednesday before sunshine returns to the East Coast later in the morning.
