Thunderstorms possible later today for the Rio Grande Valley

From the National Weather Service in Brownsville

There is a slight chance for thunderstorms Wednesday across deep South Texas, according to the National Weather Service in Brownsville. There is also a slight chance for severe storms in the northwestern ranchlands.

These storms are expected to form as an upper-level low pressure system moves across Texas later today and drags a cold front through the region late tonight.

The best chance for as severe storm is late Wednesday afternoon into Wednesday night for the northern ranchlands, where there is a slight to marginal risk for severe weather. Possible hazards include damaging winds at or in excess of 60 mph, large hail, occasional to frequent lightning and perhaps an isolated tornado.

High temperatures will reach the upper 80s in most locations Wednesday (upper 70s on the coast and near 90 out west). Breezy conditions are expected east of U.S. Highway 281.
