…Severe Storms Possible This Evening through Early Wednesday Morning…

Area of Concern:

All of South Central, but primarily near the I-35 corridor west to the Rio Grande.

Threats & Impacts:

Winds: Straight-line wind gusts up to 70 mph.

Hail: Hail up to 2 inches in diameter

Tornadoes: Isolated tornadoes possible.

Rainfall: 1 to 2 inches of rainfall across the Hill Country and Central Texas. 1/10 to 1 inch elsewhere.

Timing and Overview:

A storm system will bring a good chance of showers and storms to the region tonight. Conditions will be favorable for some storms to become severe, with the primary threats being damaging straight-line wind gusts and large hail. A lesser, but non-zero, threat for isolated tornadoes will exist. Some isolated pockets of heavy downpours are possible, however due to the speed of the system significant flash flooding impacts are not anticipated at this time.

The storms are expected to develop across West Texas and the southern Edwards Plateau by early this evening. The storms may organize into a broken line of storms that will move through the Hill Country late this evening, and into the I-35 corridor between midnight and 6 AM Wednesday. The storms will continue east of the I-35 corridor Wednesday morning, however some models indicate a weakening trend during that time.
