Weather Underground midday recap for Wednesday, January 16, 2013.
Snow and freezing rain moved into New England on Wednesday, while heavy rain showers continued across the Southeast. A frontal boundary lingered over the Southeast and triggered more heavy rains from the Lower Mississippi River Valley through the Mid-Atlantic states. As this system advanced northeastward, cooler temperatures in the north allowed for rain showers to turn to freezing rain and snow showers from the Central Appalachians through Maine. Snowfall accumulation ranged from 3 to 6 inches by mid-day on Wednesday, while rainfall totals varied around an inch. Coatesville, Pennsylvania reported 1.04 inches of rain, while Greenville, New York reported 5.5 inches of new snow. Temperatures southeast of the frontal boundary remained in the upper 70s to lower 80s, while temperatures behind the front ranged in the mid-30s.
Behind this system, a strong arctic cold front dropped southward from western Canada and created scattered snow showers across the Dakotas and Upper Midwest. Snowfall accumulation has varied around 1 to 2 inches, but cooler temperatures associated with this front allowed for highs to range in the teens and overnight lows dipped into the negative teens across the Northern Rockies. Out West, high pressure maintained chilly but dry conditions with plenty of sunshine for most of the West Coast and Desert Southwest.
Temperatures in the Lower 48 states Wednesday have ranged from a morning low of -18 degrees at Alamosa, Colo. to a midday high of 86 degrees at Brunswick, Ga.
