Storms Possible Tonight

Good Afternoon Folks…

Breezy southerly winds continuing to pump in plentiful amounts of Gulf moisture into central and south central Texas ahead of our next approaching upper level storm system and its associated surface cold front.

Returning moisture combined with an approaching upper level disturbance (pocket of cold air aloft) will trigger a chance for showers and thunderstorms across the area late this evening into early Thursday morning.

With this in mind, the Storm Prediction Center (SPC) has placed ALL of central and south central Texas (including the Austin/San Antonio Metro Areas) under a MARGINAL RISK for severe weather tonight (large hail and damaging wind gusts being the primary threats). A marginal risk is the lowest risk of severe weather possible, slight risk of severe weather comes into play from Waco north into the Great Plains, those areas shaded in yellow will have a better chance of seeing severe weather.

Dark Green = Marginal Risk
Yellow = Slight Risk



The Storm Prediction Center defines a MARGINAL RISK as such:

“Isolated severe thunderstorms possible that will be limited in duration and/or coverage and/or intensity…Thunderstorm winds of 40-60 mph possible, hail up to 1” in diameter possible, LOW tornado risk”

Storm Timeline:

The cold front, or lifting mechanism for the showers/storms will approach the northwestern Hill Country after 9 p.m. and approach the I-35 corridor after 11 p.m. and areas east of I-35 after midnight. Storms will be possible along and just behind the frontal boundary.

Storms should be long gone by sunrise Thursday as breezy northerly winds transport cooler and drier air into the area.

Cooler/Breezy Conditions Thursday behind Cold Front:
Highs on Thursday only forecast to reach the upper 60s/lower 70s area wide with a breezy north wind gusting 20-30 mph…temperatures drop into the 40s area wide Thursday night under a clear sky as winds relax.
