Weather Underground midday recap for Monday, February 11, 2013.
The strong winter storm that brought blizzard conditions to the north-central U.S. and tornadoes to the Southeast on Sunday lifted northeastward across the Great Lakes towards southeastern Canada on Monday. As the system progresses, a cold airmass over the Upper Great Lakes supported a mix of freezing rain, sleet and snow across the region. A coating to about two tenths of an inch of ice was expected in the upper tier of the Great Lakes, especially in the higher/elevated terrain of the area. This mixture of precipitation also spread across the Northeast as the system shifted eastward. Wintry precipitation in southern New England began to change into rain showers by the afternoon.
Meanwhile, the associated cold front pushed eastward through the Eastern Valleys and across the Mid-Atlantic with light to moderate scattered showers, while the southern half of the disturbance remained stretched across the Southeast. A broad swath of southwesterly flow streaming across the Southern Plains and Southeast and allowed moisture to focus along and near the cold front. This translated into widespread to scattered rain showers with areas of moderate to locally heavy rain and ongoing thunderstorms near the Gulf Coast from eastern Texas and Louisiana through Mississippi, Alabama, Georgia and the Florida Panhandle.
Temperatures in the Lower 48 states Monday have ranged from a morning low of -25 degrees at Yellowstone, Wyo. to a midday high of 86 degrees at Plant City, Fla.
