Weather Underground Forecast for Friday, August 02, 2013.
Areas of active weather will continue across the nation on Friday. In the center of the country, a low pressure system over the Central Rockies will advance eastward and further into the Plains on Friday. Flow around this system will pull warm and moist air northward from the Gulf of Mexico, creating a warm front. This front will lead this system eastward, stretching over the Northern Plains and Upper Midwest, triggering scattered showers and thunderstorms. There is a slight chance that this system may create some severe thunderstorms with strong winds, hail, and periods of heavy rainfall. Meanwhile, a weaker cold front extends southwestward behind this system bringing scattered storms to the Southern Rockies. The northern side of this system will allow for storms to linger over the Northern Rockies and Intermountain West for most of the day.
In the East, a low pressure system over eastern Canada continues pulling a cold front over the East Coast. As this front finally pushes offshore early in the day, showers and thunderstorms will diminish allowing for high pressure and dry conditions to spread across the East. The tail end of the front will linger over the Southeast, triggering a few more scattered storms over Florida and the northern shores of the Gulf of Mexico.
Temperatures in the Lower 48 states Thursday have ranged from a morning low of 33 degrees at Truckee-Tahoe, Calif. to a high of 108 degrees at Needles, Calif.
