National Weather Summary for Friday, August 19, 2016

by David Moran, on Aug 19, 2016 11:58:47 AM

Scattered thunderstorms are expected to develop over portions of the Central and Southern Plains, as well as into the Upper Mississippi Valley, on Friday as a cold front moves across the Plains. Across Eastern Colorado, a few thunderstorms may develop as an upper level trough moves across the region. Deep moisture in place across southwest Texas will allow for heavy rain across the region. The cold front moving across the Plains will allow for the development of strong to severe thunderstorms across portions of the Midwest. The same cold front will act as a focus for the development of thunderstorms capable of heavy rain across portions of Central and Southern Texas. This activity will continue into Sunday, leading to flash flooding in some areas.
