The nation's weather

Weather Underground Forecast for Friday, August 24, 2012.

Active weather continues across the middle of the nation on Friday as a trough of low pressure continues pushing a cold front through the Plains and Midwest. This will pull moisture and energy in from the Gulf of Mexico and support showers and thunderstorms from the Great Lakes through the Central and Southern Plains. There is a chance that these storms will turn severe with periods of heavy rainfall, strong winds, and large hail. Flow from the south will continue pushing warm and moist air into the Plains, allowing for highs to reach into the 90s across the Dakotas.

Just south of this activity, an area of low pressure in the western Gulf of Mexico pushes abundant moisture into southeastern Texas. This will create heavy rainfall from eastern Texas through the Lower Mississippi River Valley on Friday.

In the East, a ridge of high pressure will remain the dominant weather feature across the Eastern Valleys. This will keep the region warm and sunny with dry conditions. Highs will range in the 80s and 90s across most of the Eastern states.

In the West, scattered thunderstorms are expected to persist across the Great Basin as well as the Southern and Central Rockies due to monsoonal moisture lingering over the region. In the Northwest, a cold front moves over the Intermountain West and into the Northern Rockies, pulling cooler conditions into the Pacific Northwest. Fire danger will remain high for the Northwestern corner of the nation as dry conditions prevail. Temperatures in the Lower 48 states Thursday have ranged from a morning low of 32 degrees at West Yellowstone, Mont. to a high of 98 degrees at Fort Madison, Iowa
