Weather Underground Forecast for Tuesday, July 16, 2013.
Wet weather will continue for the Southern Plains and the Southwest on Tuesday as an upper low over the Southern Plains shifts further west. This system, combined with moist, favorable environmental conditions, will kick up moderate to heavy rainfall and slow moving thunderstorms, especially in parts of west Texas from the southern Panhandle to Big Bend country and southeastern Arizona. Excessive rainfall in drought-stricken areas will likely cause runoff and flooding. A Flash Flood Watch has been issued for the region in anticipation of Tuesday¼’s precipitation.
Meanwhile, to the north, a few showers will remain focused along parts of a nearly stationary frontal boundary extending across Nebraska, the Northern Plains and parts of Minnesota.
In the East, hot and humid conditions will spread across the East and parts of the Midwest as a subtropical ridge of high pressure over the Eastern U.S. begins to nose westward. Expect hot temperatures to continue through the next few days. Elsewhere in the East, scattered showers and thunderstorms will persist in the Southeast.
Temperatures in the Lower 48 states Monday have ranged from a morning low of 35 degrees at Stanley, Idaho to a high of 108 degrees at Needles, Calif.
