Weather Underground midday recap for Sunday, April 07, 2013.
Active weather developed across the northwestern quadrant of the nation on Sunday as a strong and cold storm system began to dip into the West. Ample moisture spread across the Pacific Northwest and northern California coasts as the system progressed and an associated low pressure system trekked eastward through the Northwest. This setup led to widely scattered rain showers, high elevation snow, chances of thunderstorms, and periods of high winds from the Pacific Northwest and portions of northern California through the Northern and Central Rockies. A variety of Winter Weather Advisories, Winter Storm Warnings, and Wind Statements continued for the higher elevations of these areas in anticipation of snow accumulation of up to 6 to 14 inches and wind gusts to 60 mph.
Ahead of this activity, moist flow from the western Gulf of Mexico spread moisture into the Southern and Central Plains, while a frontal disturbance reached across the Northern and Central Plains. Rain showers formed in the Dakotas through the afternoon, while rain and thunderstorms picked up in Nebraska and Kansas. There was a slight risk of severe thunderstorms from the afternoon through Sunday night for northwestern Oklahoma, much of Kansas, and western and central Missouri. While the main concerns with these storms were isolated, very large hail and damaging wind gusts, a tornado or two were possible during the evening hours. As of this afternoon, two quarter sized hail events were reported from Butler County, Kansas.
Further East, areas of rain and light snow formed in the Northeast ahead of a warm front that pushed across the Lower Great Lakes ad into the region.
Temperatures in the Lower 48 states Sunday have ranged from a morning low of 10 degrees at Mt. Washington, N.H. to a midday high of 89 degrees at Fort Stockton, Texas
