KEY MESSAGES

- Low to medium chances for showers and thunderstorms Thursday and Friday.

- An unsettled weather pattern remains this weekend into next week. There is potential for severe thunderstorms with heavy rain this weekend.

SHORT TERM

(Tonight through Thursday night) Issued at 1230 PM CDT Wed Apr 8 2026

Near seasonable high temperatures under mostly sunny to partly cloudy skies are expected today with surface high pressure to the east bringing southeasterly flow to the area. This pattern brings above normal moisture to the area beginning this afternoon remaining into next week. While a few sprinkles or very light showers cannot be ruled out into this evening, mainly dry conditions are expected today before we head into a more unsettled pattern with southwesterly flow aloft. The humid airmass will allow for low cloud cover to develop over all of South Central Texas tonight bringing lows in the mid 50s to mid 60s. Expect some streamer showers to develop Thursday morning, with better chances for showers and thunderstorms in the afternoon when we see peak heating. With relatively weak instability, shear and forcing this day, expect storms to be disorganized and non-severe Thursday into Thursday night.

LONG TERM

(Friday through next Wednesday) Issued at 1230 PM CDT Wed Apr 8 2026

A longwave trough begins to move over the western US Friday, gradually moving east over the weekend into next week. This pattern will set up our rain chances that continue throughout the entire long term forecast as a series of shortwaves bring multiple rounds of showers and thunderstorms to our area. With above normal moisture over the area, there remains the potential for locally heavy rainfall with thunderstorms along with the threat for severe weather.

Increased moisture and a disturbance over the area will bring chances for scattered showers and thunderstorms Friday favored in the southern half of the CWA in the morning with precipitation chances increasing across the entire area in the afternoon. Similar to Thursday, any activity looks to be disorganized and non-severe this day.

Our set up evolves over the weekend as shear and instability increase over Texas ahead of the aforementioned longwave trough bringing a higher potential for severe weather to our area. On Saturday, the main severe threat looks to be over our western areas, particularly the southern Edwards Plateau where thunderstorms develop near a dryline west of the area and move into this location during the evening or overnight hours. Ahead of this activity there could be some scattered showers and isolated thunderstorms, though exactly when and where they form is still uncertain. Our severe threat continues Sunday with SPC highlighting the southern Edwards Plateau, Hill Country, and portions of the I-35 corridor for strong to severe storms during the afternoon and evening. With above normal PWATS in place through the entire weekend, storms may also produce locally heavy rainfall which could lead to flooding.

We continue under southwesterly flow into the middle of next week as the main trough lingers over the southwestern US. Precipitation chances continue during this time and additional rounds of wet weather will be possible along the a potential for severe weather and flooding, though there is low confidence on details at this time. If you have outdoor plans in the next seven days, keep up with the forecast.
