Weather Underground Forecast for Tuesday, April 23, 2013.
Active weather will continue across the nation¼’s mid-section on Tuesday as a frontal boundary cutting across Central U.S. reaches from the Upper Great Lakes southwestward through the Southern Plains. A cold airmass behind this disturbance will maintain unseasonably cold temperatures from parts of the Upper Midwest into the Central Plains and allow moderate to heavy snow showers and areas of mixed wintry precipitation to develop from parts of Michigan¼’s Upper Peninsula and Wisconsin through portions of Kansas and into eastern Colorado. Areas of the Upper Midwest may pick up 6 to 9 inches of wet snow through Tuesday, while lighter snow accumulations of up to 2 inches with ice accumulations of up to a tenth of an inch become possible in the Central Plains. Meanwhile, areas near and ahead of the frontal disturbance from the Great Lakes into Lower Mississippi Valley and the Southern Plains will see light to moderate rain showers and chances of thunderstorms
Meanwhile to the east of this activity, showers and thunderstorms will taper down across the Florida Peninsula as the cold front impacting the area shifts eastward and it¼’s associated low pressure lifts north-northeastward off the Mid-Atlantic coast. Rain showers will become possible along the Mid-Atlantic and New England coasts as this system lifts.
Temperatures in the Lower 48 states Monday have ranged from a morning low of 7 degrees at Cut Bank, Mont. to a high of 88 degrees at Needles, Calif.
