Weather Underground Forecast for Friday, May 11, 2012.
Expect more wet weather for Texas, while dry conditions are anticipated for both the East and West Coasts on Friday. An area of low pressure lingers over eastern Texas, bringing more heavy rain showers and strong thunderstorms to the state. As this system pulls abundant moisture and energy in from the Gulf of Mexico, expect some of these storms to turn severe with heavy downpours, strong winds, large hail, and possibly a tornado or two. Rainfall totals will range around 2 inches, with up to 3 inches likely in areas of severe thunderstorm development. Thus, flooding will remain a concern for much of Texas on Friday.
In the North, a low pressure system moving through Canada pulls a frontal boundary through the Northern Plains and into the Great Lakes. This will kick up widespread showers and thunderstorms that will stretch into the Central Plains, but severe thunderstorm development is not likely with this system.
In the East, a ridge of high pressure builds over the Eastern Valleys and East Coast. This pushes moisture away to the south, allowing for dry conditions to return. Meanwhile, the West will remain dry as high pressure builds northward from the Southwestern US. The Northwestern corner of the nation will see a chilly morning after the passage of a cold front. Expect frost and freeze advisories to remain in effect for the parts of the Pacific Northwest and Intermountain West. Temperatures in the Lower 48 states Thursday have ranged from a morning low of 19 degrees at Redmond, Ore. to a high of 91 degrees at China Lake, Calif.
