KEY MESSAGES

- Mild and dry weather continues through midweek.

- Active weather pattern returns late week and into the weekend.

SHORT TERM

(Tonight through Wednesday night) Issued at 1236 PM CDT Tue Apr 7 2026

Surface high pressure centered over the eastern two thirds of the United States will slide eastward as the week continues. Southeasterly wind flow will prevail at the surface which will allow moisture to advect into the region from the Gulf. When combined with a mid-level disturbance moving across northern Texas late tonight into Wednesday, increased cloud cover is expected over much of the region moving from west to east over time.

Overnight low temperatures will be mild ranging from the lower 50s in the Texas Hill Country to the mid 50s along the Interstate 35 corridor to the upper 50s along the Rio Grande. Maximum temperatures on Wednesday will climb into the 70s across the area with some potential low 80s sneaking in across southern and eastern areas with less cloud cover.

LONG TERM

(Thursday through next Tuesday) Issued at 1236 PM CDT Tue Apr 7 2026

As the surface high is pinched east over the eastern third of the United States, a more unsettled pattern will develop over the central third of the country opening the door to increasing rain chances over South Central Texas late week into the weekend and potentially even into early next week. Besides the increasing moisture there will also be a warming trend with lower to mid 80s by the weekend across most of the area with the Edwards Plateau remaining a few degrees cooler.

A long wave trough moves into the southwestern United States and ejects northeast across the central third of the country enabling a more unstable environment with deep layer wind shear capable of supporting strong thunderstorm activity. The Storm Prediction Center has areas outlooked for the Edwards Plateau and portions of the Rio Grande Plains on days 5 (Saturday) and 6 (Sunday). Some beneficial rainfall may be possible this weekend into next week as well but the potential for heavy rainfall will need to be monitored.

AVIATION

(18Z TAFS) Issued at 1236 PM CDT Tue Apr 7 2026

Generally VFR though some MVFR cigs/vsbys could sneak into some of the terminals late tonight into Wednesday morning. Light and variable winds continue at night while daytime winds will be due east or southeast at 7-15 knots.
