Weather Underground midday recap for Tuesday, April 23, 2013.
Active weather continued across the nation¼'s mid-section on Tuesday as a frontal boundary cutting across Central U.S. reached from the Upper Great Lakes southwestward through the Southern Plains. A cold airmass behind this disturbance maintained unseasonably cold temperatures from parts of the Upper Midwest into the Central Plains and allowed 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 were expected to 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 experienced light to moderate rain showers and chances of thunderstorms.
Meanwhile to the east of this activity., showers and thunderstorms tapered off across the Florida Peninsula as the cold front impacting the area shifted northeastward and it¼'s associated low pressure lifted north-northeastward off the Mid-Atlantic coast. Rainy and windy weather conditions were possible along the parts of the Mid-Atlantic and New England coasts due to the offshore low.
Temperatures in the Lower 48 states Tuesday have ranged from a morning low of -9 degrees at Yellowstone, Wyo. to a midday high of 91 degrees at Thermal, Calif.
