HARLINGEN, Texas (ValleyCentral) — An aggressive storm system is moving across a wide swath of Texas this evening and overnight generating a serious threat of severe weather.

Areas north of San Antonio, Houston and across the ArkLaTex (including Dallas) will be under the gun for very strong storms producing hail, flooding rain and tornadoes.

As the cold front, leading edge of cooler air, slips through the Valley overnight you can expect a dramatic wind shift with some gusts from 30 to 40 miles per hour.
No storms, or even rain, are expected anywhere along Deep South Texas with this system; just windy, cooler and dyer.

The dryer air blowing in will trigger a fire weather warning for the entire Rio Grande Valley from 10 p.m. tonight through 9 a.m. Friday.
