Weather Underground midday recap for Monday, January 21, 2013.
Cold temperatures gripped the northeastern quadrant of the nation on Monday as a cold arctic airmass prevailed across the region. Daytime highs ranged from below zero in parts of the Dakotas and Upper Mississippi Valley to the single digits in the Upper Great Lakes and interior Northeast to the 30s across parts of the Lower Ohio Valley and New England areas as cold northwesterly flow whipped across the region. Bitterly cold temperatures combined with northwest winds of 10 to 15 mph and higher gusts created dangerously cold wind chills of 25 to 45 below zero during the morning and nighttime hours across parts of the Dakotas through Wisconsin and in parts of the upper Northeast.
Meanwhile, low pressure cut across the Great Lakes this afternoon and headed toward the Northeast with lake effect snow showers. While this system had a limited amount of moisture to work with, snow accumulations were expected to be fairly heavy in immediate downwind areas-including western Michigan and areas from northeastern Ohio through the lakeshore areas of upstate New York. Snow accumulations were expected to range from 6 to 10 inches in western Michigan and between 10 to 20 inches in areas from northeastern Ohio through the lakeshore areas of upstate New York.
Elsewhere, outside of a few light showers in the Florida Peninsula, a quiet weather day developed across the rest of the nation as high pressure remained dominant in the West.
Temperatures in the Lower 48 states Monday have ranged from a morning low of -25 degrees at Bigfork, Minn. to a midday high of 82 degrees at Camarillo, Calif.
