Weather Underground midday recap for Friday, December 21, 2012.
Wet and snowy weather spread across the Western states and a strong winter storm moved from the Great Lakes into the Northeast on Friday. A low pressure system that brought heavy snow and blizzard conditions to the Upper Midwest and Great Lakes has moved eastward and into the Northeast. The leading edge of this system pulled warmer air in from the south, which allowed for rain showers to develop in parts of the far Northeast. At the same time, the back side of this system pulled colder air in from the north and allowed for rain showers to turn to snow showers across the Great Lakes and Northeast. Snowfall totals ranged from another 3 inches in parts of Wisconsin and Michigan, to 6 inches in far western New York state. Strong winds allowed for blowing snow and poor visibility to continue, however, blizzard warnings have not yet been issued for the region. Strongest wind gusts were reported up to 124 mph at Mount Washington, Vermont, while most areas from the Great Lakes through the Northeast saw gusts up to 40 mph. Higher elevations of the Northern and Central Appalachians saw the heaviest snowfall with accumulation over 10 inches by Friday evening. The cold front associated with this system that extended southward advanced eastward and offshore. This brought an end to showers and thunderstorms across the Southeast and Mid-Atlantic states.
Out West, a strong winter storm off the West Coast continued to push a cold front down the West Coast. Abundant moisture associated with this system allowed for heavy rain and heavy snowfall to spread through northern and central California. Heaviest rainfall associated with this system was reported in Ukiah, California with a mid-day total of 1.41 inches and snowfall accumulations over a foot were anticipated in the Sierra Nevadas.
Temperatures in the Lower 48 states Friday have ranged from a morning low of -27 degrees at Kremmling, Colo. to a midday high of 75 degrees at Key West, Fla.
