Weather Underground midday recap for Tuesday, November 13, 2012.
The main weather producer for Tuesday was the cold front that moved off the East Coast and dumped widespread showers and scattered thunderstorms from New England southwestward through the Mid-Atlantic and Southeast Coast. This cold front also brought much colder temperatures across the Eastern U.S. The Northeast and Mid-Atlantic, especially, temperatures dropped 10 to 15 degrees from Monday¼'s highs. Temperatures remained mostly in the 40s and near 50 throughout the day Tuesday. In addition, some lake effect snow occurred Tuesday morning over the Great Lakes, with the heaviest over the Upper Peninsula of Michigan. The last 24 hour snowfall total reached near 6 inches.
Moving to the West, coastal rain and showers continued over the Pacific Northwest and portions of the northwestern California Tuesday. Some high elevation snow also fell over the northern Intermountain West. Otherwise, high pressure brought mostly sunny skies throughout southwestern U.S.
Elsewhere, some upper level energy combined with moist onshore flow from the Gulf of Mexico aided in producing scattered showers in southern Texas.
Temperatures in the Lower 48 states Tuesday have ranged from a morning low of 3 degrees at Cando, N.D. to a midday high of 82 degrees at Punta Gorda, Fla.
