Weather Underground Forecast for Sunday, November 11, 2012.

Active weather will move through the Plains and toward the Mississippi River Valley on Sunday, while snow showers persist in the North. A strong low pressure system continues moving northeastward from the Northern Rockies and into central Canada. Flow around this system will continue pushing cool air from Canada into the Northern Plains, allowing for scattered snow showers to persist for North Dakota and parts of northern Minnesota. Strong winds will allow for areas of blowing snow to persist as well. Snowfall totals in these areas will range from 3 to 5 inches on Sunday. Cold air will also linger over the Rockies and Plains. Expect high temperatures to remain 15 to 30 degrees below seasonable for these areas. The cold front associated with this system will continue advancing eastward through the Plains and into the Mississippi River Valley. Flow ahead of this front will pull warm air and moisture in from the Gulf of Mexico, allowing for showers and thunderstorms to develop from the Great Leak, through eastern Texas. There is a chance that these storms will turn severe over the Lower Mississippi River Valley and Southern Plains, due to ample Gulf moisture over the region. Expect large hail, damaging winds, and even possibly a tornado or two to develop Sunday afternoon and evening.

Out West, another low pressure system spinning in the Gulf of Alaska will push another front toward the Pacific Northwest. This will bring moisture onshore with it, allowing for more rain and high elevation snow to develop late Sunday and into Monday. The Cascades may see 2 to 4 inches of new snow above 3,000 feet.

Temperatures in the Lower 48 states Saturday have ranged from a morning low of 1 degrees at Butte, Mont. to a high of 88 degrees at Edinburg, Texas
