Weather Underground midday recap for Saturday, December 29, 2012.
Wet and snowy weather quickly returned to the Northeast on Saturday as a strong winter storm advanced northward over the Eastern Valleys. This system moved over the Upper Ohio River Valley and into the Northeast, bringing heavy rains and strong winds to the Eastern Seaboard and heavy snow from the Great Lakes through Maine. Snowfall accumulation ranged from 2 to 4 inches from Ohio through New York state, while higher elevations of the Northern and Central Appalachians saw snowfall accumulation from 9 to 11 inches. Strong wind gusts reached over 50 mph in some areas. Montgomery, New York reported the strongest winds gust at 67 mph. Lake effect snow showers developed along downwind shores of the Great Lakes across eastern Wisconsin, northern Illinois, as well as most of Michigan and Indiana. Heaviest lake effect snowfall was reported in eastern Wisconsin and ranged from 6 to 8 inches.
In the South, cold air continued to pour into the Southeast from Canada and the central U.S. This allowed for daytime highs to remain in the 50s for the Lower Mississippi Valley, the Tennessee Valley, and northern Florida.
Meanwhile out West, a low pressure system continued to move down the West Coast. This allowed for a front to linger right along the coast, kicking up more rain showers from central through southern California. Light snow showers developed across the Sierra Nevadas. To the north, a few scattered rain and mountain snow showers persisted for parts of the Pacific Northwest as onshore flow continued.
Temperatures in the Lower 48 states Saturday have ranged from a morning low of -25 degrees at Kremmling, Colo. to a midday high of 84 degrees at Fort Lauderdale, Fla.
