Weather Underground Forecast for Wednesday, January 23, 2013.
Cold temperatures and lake effect snow showers will continue across the northeastern quadrant of the nation on Wednesday, while a Pacific cold front reaches the West Coast with precipitation.
In the East, the cold dome of high pressure over the Midwest will slide southeastward to the Eastern Gulf Coast, allowing for a touch of cold weather from the North to reach the Upper Southeast areas. Meanwhile, to the north, bitter cold conditions with well below average temperatures will continue across the Midwest, Northeast, and parts of the northern Mid-Atlantic. Highs across the region are expected to range from below zero in parts of the Dakotas, Upper Mississippi Valley, and the Upper Northeast to the single digits in the Upper Great Lakes and interior Northeast to the 30s across parts of the Ohio Valley, Lower New England, and Upper Mid-Atlantic. Bitterly cold temperatures combined with west to northwest winds of 10 to 15 mph and higher gusts will lead to dangerously cold wind chills as low as 40 below zero during the morning and nighttime hours across parts of the Dakotas through the Great Lakes and Ohio Valley and the Upper Northeast.
Meanwhile, in addition to seeing some of the coldest temperatures and wind chills of the season, a lake effect snow event will continue downwind of the Great Lakes. New snow accumulations will be fairly moderate in immediate downwind areas-including western Michigan and areas from northeastern Ohio through the lakeshore areas of upstate New York through Wednesday. Another 2 to 5 inches of snow are expected in western Michigan, while another 4 to 8 inches are expected from areas of northeastern Ohio through the lakeshore areas of upstate New York.
Shifting to the West, a Pacific cold front will reach the West Coast with sufficient moisture, kicking up rain and high elevation snow in the Pacific Northwest. This activity will spread into northern and central California through Wednesday evening.
Temperatures in the Lower 48 states Tuesday have ranged from a morning low of -34 degrees at Crane Lake, Minn. to a high of 82 degrees at Camp Pendleton, Calif.
