Weather Underground midday recap for Sunday, April 14, 2013.
A late season winter storm hit the North-Central U.S. with another dose of wintry precipitation late Saturday night through Sunday. The storm system pulled moisture from the Gulf of Mexico northward as it moved off the Rockies and into South Dakota and Nebraska on Sunday, allowing for a swath of snow showers to blanket areas from the Northern High Plains into the Upper Great Lakes. Moderate to heavy snow developed to the north and northwest of this system in the Dakotas and Montana and left up to 12.5 inches of snow by the afternoon. Areas of north-central North Dakota experienced blizzard conditions this afternoon with heavy snow, lowered visibilities due to northeast winds gusting to 40 mph, and extremely dangerous road conditions. Snow accumulations in this region were expected to reach up to 18 inches on Sunday. On the northeastern side of this system, snow and a mix of precipitation including freezing rain, sleet and rain, developed to the north of an associated warm front, across parts of Minnesota, Wisconsin, and Michigan, while scattered rain showers fell across Iowa. Areas of northern Minnesota remained under a Winter Storm Warning through the evening in anticipation of up to 8 inches of snow and strong winds, while Winter Weather Advisories continued for central Minnesota into northwestern Wisconsin in anticipation of 2 to 5 inches of snow. Meanwhile, strong to severe thunderstorms were expected ahead of an associated cold front from parts of the eastern Central Plains through Mid-Mississippi Valley from late Sunday afternoon through the evening. The main concern with these storms were damaging wind gusts and hail.
In the Southeast, heavy rain and organized thunderstorms developed in the southeastern corner of the nation on Sunday as a warm frontal disturbance lingered along the northeastern Gulf Coast and rich tropical moisture streamed northward across the central Gulf Coast. Much of northern Florida remained at slight risk of severe weather development through the afternoon with damaging wind, hail, and possible tornadoes. As of this afternoon, several high wind events were reported along the central Gulf Coast with downed trees and power lines.
Temperatures in the Lower 48 states Sunday have ranged from a morning low of 1 degrees at Ely, Minn. to a midday high of 93 degrees at San Angelo, Texas
