Weather Underground midday recap for Sunday, Dec. 22, 2013
An active weather system associated with an extensive cold front trekked across the eastern third of the country on Sunday, while a ridge of high pressure kept the Southwest clear of precipitation.
A cold front extended from the Gulf Coast to the Ohio Valley on Sunday, which provided widespread rain and thunderstorms to the East Coast. Showers and thunderstorms affected Alabama, Georgia, South Carolina, North Carolina, Virginia, Maryland and Pennsylvania. Evergreen, Ala., reported a midday total of 3.02 inches of rain, while Cartersville, Ga., reported a midday total of 2.60 inches of rain. Due to how slow this system moved across the region, flood warnings were issued in a handful of these states. Meanwhile, a strong low pressure system associated with the cold front moved across the eastern portion of the Great Lakes. This area of low pressure drew an arctic air mass over the Northeast, which initiated freezing rain and snow showers across the upper Midwest and parts of the Northeast. Niagara, N.Y., reported a midday total of 0.35 inches of ice on Sunday.
Out west, a weak area of low pressure pushed across the Pacific Northwest. This system provided spotty showers to Washington and light snow showers to the Cascades. A high pressure system kept conditions sunny from the Southwest to the southern Plains on Sunday.
Temperatures in the Lower 48 states Sunday have ranged from a morning low of -23 degrees at Tioga Municipal Airport, N.D. to a midday high of 89 degrees at Immokalee, Fla.
