Weather Underground Forecast for Wednesday, February 13, 2013.
Unsettled weather continues across the southeastern corner of the nation and spreads into the Mid-Atlantic on Wednesday as the storm system of the Deep South lifts from the Central Gulf Coast States to the southern Mid-Atlantic coast. Light to moderate rain, periods of heavy coastal rain, and thunderstorms are expected ahead and just north of the system in the Southeast, the southern Mid-Atlantic, and the Tennessee Valley, while light to moderate snow showers are anticipated further north of the system in the lower Ohio Valley and northern Mid-Atlantic. In the South, strong thunderstorms organizing over portions of southern Georgia, extreme southeastern Alabama, and northern Florida may turn severe, creating a slight risk of damaging wind gusts and conditional tornado risk. For the North, wintry precipitation will pick up across the northern Mid-Atlantic-becoming heavy at times-and will spread into southern New England during the evening hours.
Out West, onshore flow will maintain chances of light to moderate rain showers and high elevation snow showers in the Pacific Northwest. Meanwhile, energy streaming southeastward across the Northwest and Northern Plains will trigger more snow showers across the Northern Rockies and chances of snow in the Central Rockies.
Temperatures in the Lower 48 states Tuesday have ranged from a morning low of -20 degrees at Kremmling, Colo. to a high of 86 degrees at Plant City, Fla.
