…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.

Confidence:

Moderate to High

There is a slight risk for severe thunderstorms Tuesday night into Wednesday as a large upper-level disturbance moves into the Central United States. The severe weather threat will be generally along and west of I-35 Tuesday night, and along and east of I-35 during the day Wednesday. Large hail and damaging winds will be primary threats. However, this slow moving storm system will also be capable of producing isolated tornadoes and locally heavy downpours of 1 to 3 inches.

Severe thunderstorms will be possible beginning Tuesday evening as a strong upper level system moves across the southern United States. Large hail, damaging winds, and even some tornadoes will be possible. The most favorable conditions for severe weather will be west of Interstate 35. These storms will also be capable of producing heavy rainfall, resulting in some localized flooding.

Our severe weather this week will likely span through Wednesday as well. By daybreak, the threats should be mostly east of I-35. These storms will still carry the threat for large hail, damaging winds, and isolated tornadoes, and locally heavy rainfall.

A strong upper level disturbance will bring a good chance of showers and thunderstorms to South Central Texas late Tuesday night and Wednesday. Strong to severe thunderstorms and locally heavy rainfall may be possible with these storms. Drier conditions will take over for Thursday into Friday, but another storm system moves into the area over the weekend. Above normal temperatures are expected over the next several days.
