KEY MESSAGES

- Chances for showers and thunderstorms increase Tuesday through Saturday as an active weather pattern resumes.

SHORT TERM

(Tonight through Tuesday night) Issued at 102 PM CDT Mon Jun 1 2026

Mid-level ridging remains over our area but should begin to break down and slide off to the east by Tuesday. Regardless we could still see some isolated streamer showers and thunderstorms pop off over the Coastal Plains. Otherwise most of the area should remain dry for the remainder of today. Temps have risen to to the mid 80s to near 90, we should see temps climb a few more degrees with most topping out in the low 90s before the day ends. For tonight it will remain mild with most staying in the low to mid 70s as clouds increase overnight and moisture remains trapped across the area, leading to a warm and humid evening.

A dryline will be stationed off to our west in West TX and will try to make progress westward each day with convection possibly forming along it. Simultaneously an inverted trough located over the northern Gulf will attempt to make its way westward into our area. Moisture will be plentiful as PWATs rise above 1.5 inches, so any storms that do fire off will be capable of producing torrential rainfall and perhaps some brief gusty winds in the strongest storms. Our eastern and northern areas would have the highest chances of seeing storms if they form. By Tuesday night we could see some lingering convection however most activity should die off after sunset leading to another warm and moist overnight with many remaining in the low to mid 70s.

LONG TERM

(Wednesday through next Monday) Issued at 102 PM CDT Mon Jun 1 2026

Our active pattern continues into Wednesday as southwesterly flow aloft rears its head once again. Allowing multiple disturbances to cross over our area bringing increased chances of rainfall. However, most activity should be isolated to scattered in nature and not as widespread as our recent events have been. We could see this pattern remaining through at least Friday before a Low located off the Baja Peninsula ejects northeastward over Mexico and eventually moves into central to northern TX over the weekend. As it does so, we should see chances for showers and storms begin to increase. Several model ensembles suggest PWATs increasing to 1.8 to perhaps 2.00 inches+ meaning any storms that do form could have the potential to produce torrential rainfall. While the weekend doesnt look like a complete washout, it is trending wetter as more model runs come in. It should be stressed that these patterns are notoriously difficult to pin down regarding individual rounds and amounts so far out in time. We should have a better handle and clarity on this as we get closer. Stay tuned and check back to the forecast often.

AVIATION

(18Z TAFS) Issued at 1232 PM CDT Mon Jun 1 2026

The Austin and San Antonio terminals have rebounded to VFR. The ceiling at DRT has risen to 030, but they should reach VFR before the start of this period. VFR conditions will prevail through the afternoon and evening. Models are not in agreement on ceilings overnight tonight. We have chosen to go with MVFR/IFR overnight, but there is a small chance that all terminals stay VFR. We should also see some reduced visibility in the San Antonio area. All airports will return to VFR by around noon Tuesday.
