Midwest

Weather Underground Forecast for Monday, March 15, 2010.

Wet weather will persist in the Eastern US as a strong low pressure system slowly moves off the East Coast. The system that brought periods of heavy rain will continue bringing scattered showers from the Mid-Atlantic states, New England, and the Northeast. Expect between a quarter and a half of an inch of rain in most places as highs remain above freezing in the 40s.

Meanwhile, behind this system, a large ridge of high pressure will build over the Central US and spread over most of the Plains into the Mississippi River and Great Lakes. This will allow for plenty of sunshine and warm conditions. The Midwest will remain in the mid-50s, while the Upper Plains will see highs in the 40s.

To the South, a trough of low pressure moving across the Central Rockies will dip into the Southern Plains. This will pull moisture in from the Gulf of Mexico, which will allow for scattered showers and thunderstorms to develop over Texas and Oklahoma. Expect another cool and breezy day with highs in the 40s and 50s and winds gusting up to 25 mph.

Out West, mild weather is expected on Monday as high pressure hovers over the West Coast. A system will approach from the Pacific Ocean, but will not reach the coast on Monday. Expect sunny skies with highs in the 70s over the Pacific Northwest and California.

Temperatures in the Lower 48 states Sunday ranged from a low of 2 degrees at Bridgeport, Calif. to a high of 87 degrees at San Angelo, Texas.
