Weather Underground Forecast for Wednesday, December 18, 2013
A winter storm will continue to spread snow across the Northeast on Wednesday, before it quickly pushes offshore and into the Atlantic Ocean. Snowfall totals Wednesday morning will range from 4 to 6 inches for most areas, with up to a foot of snow possible in parts of Maine. Higher elevations of the northern Appalachians will also see some heavy snowfall in the early morning hours. The back side of this system will create northerly flow for the Great Lakes, allowing for lake effect snow showers to develop along the downwind shores. Expect periods of heavy snow fro far northeastern Ohio, northwestern Pennsylvania and far western New York State. Storm totals up to 10 inches will remain possible for these locations.
Meanwhile in the West, a trough of low pressure moves over British Columbia, pulling limited moisture onshore from the Pacific Ocean. This system will push a cold front over the Pacific Northwest on Wednesday. Due to limited moisture associated with this system, significant precipitin is not anticipated. Expect scattered and light rain for low elevations, with moderate snowfall across the northern Cascades. The leading edge of this system may create some heavy snow and strong winds across western Montana by Wednesday evening. The Southwest and Four Corners will remain dry on Wednesday as high pressure dominates.
Temperatures in the Lower 48 states Tuesday have ranged from a morning low of -27 degrees at Saranac Lake, N.Y. to a high of 97 degrees at Orange Grove, Texas
