Weather Underground Forecast for Monday, August 08, 2011.
More active weather is anticipated in the eastern half of the nation on Monday. Areas of showers and thunderstorms will develop ahead of a cold front that will extend from the Mid-Atlantic through the Mid-Mississippi Valley and into the Central Plains. Some of the storm clusters in these regions will have a slight chance of turning severe due to increased instability during the afternoon. Damaging wind will be the main threat of storms in the Lower Ohio Valley, while damaging wind and hail will be possible in the Central and Southern Plains and the parts of the Tennessee Valley. Additional showers and thunderstorms are expected to develop ahead of another cold front moving through the Midwest. Areas of the Mid- and Upper Mississippi Valley will see periods of heavy rainfall with strong storms. Storms in these areas may turn severe with isolated large hail and damaging wind.
Elsewhere in the East, chances of showers will persist in the Northeast as waves of low pressure extending through the Great Lakes into the Northeast. To the south, showers and thunderstorms will continue in Florida. Finally, hot weather will linger from the Southern Plains through the Southeast and portions of the Mid-Atlantic.
In the West, a weak trough of low pressure located near the coast will keep much of the West at near normal daytime highs. Temperatures in the Lower 48 states Sunday have ranged from a morning low of 32 degrees at Bryce Canyon, Utah to a high of 107 degrees at Little Rock, Ark.
