Weather Underground Forecast for Saturday, July 19, 2014

A cold front will extend from the southern Plains to the Tennessee Valley on Saturday, while an area of low pressure will linger over the southern Mid-Atlantic.

A cold front will stretch across the southern Plains, the western Gulf Coast and the Tennessee Valley on Saturday. As this system overrides a warm, humid air mass from the Gulf of Mexico, strong thunderstorms will develop across southern Texas, the Gulf Coast and the Tennessee Valley. In addition, temperatures are expected to drop 10 to 20 degrees below normal from the southern and central Plains to the southern Appalachians. Low pressure along the western end of the front will bring rain and thunderstorms to parts of the Intermountain West and the central Plains. Flash flooding will be possible along valleys adjacent to sloped terrain.

Meanwhile, an area of low pressure is forecast to move over the southern Mid-Atlantic. This system will usher showers and thunderstorms over the Southeast, the Mid-Atlantic, the Ohio Valley and parts of the Northeast. New England will stay mostly clear of wet weather on Saturday.

Out west, a low pressure system will drift eastward over the Pacific Northwest and the upper Intermountain West. This system will influence an onshore flow from the Pacific, which will allow for showers to develop over northwest Oregon and parts of Washington. The remainder of the West Coast will stay clear of precipitation due to a ridge of high pressure over the eastern Pacific.

Temperatures in the Lower 48 states Friday have ranged from a morning low of 39 degrees at Stanley, Idaho to a high of 105 degrees at Las Vegas, Nev.
