KEY MESSAGES

- Cooler temperatures today through Tuesday.

- Light showers continue to move across the area through this evening.

- Seasonable temps return by mid week as an active weather pattern continues into next weekend.

SHORT TERM

(Tonight through Monday night) Issued at 1255 PM CDT Sun Apr 5 2026

Current radar imagery shows showers are ongoing across the area. However when looking at actual observations not much is really accumulating meaning most activity is not reaching the ground and it's likely the radar is picking up heavier signals showing up at higher elevations. That being said expect these very light showers/drizzle to continue moving eastward across the area. At the same time drier air located over north TX is starting to make its way southward. PWATs reflect this with only 0.4 to 0.6in to the north while the more moist air (PWATs >1 inch) remain across the southern two thirds of our area. We are starting to see this dry air undercut the showers that have made it into the Hill Country with a notable decrease in intensity over the last couple of hours. All that being said most of this activity across the Hill Country and along and south of I-10 should decrease in coverage moving completely out of the area as the trough axis responsible moves off to the east. Most areas should be dry come Monday morning.

For tonight expect another cool night as temps drop into the upper 40s north to lower 50s south. Monday will be just a few degrees warmer with most areas breaking into the low 70s as clouds begin to dissipate by the afternoon hours. This should lead to another rather chilly night with lows dropping into the 40s north and low 50s south as we remain in weak northeasterly flow.

LONG TERM

(Tuesday through next Sunday) Issued at 1255 PM CDT Sun Apr 5 2026

A somewhat warmer day is in store Tuesday with highs reaching the low to mid 70s. It looks like we stay in easterly-northeasterly flow until Wednesday as low pressure across the plains and upper level ridging help to keep westerly/northwesterly flow locked in place aloft thus limiting a possible rapid warmup over our area. Global Models continue to indicate a low forming over the Baja peninsula mid week and then moving across Mexico and into West Texas either Thursday or Friday. Moisture at the surface looks fairly limited however there's enough vorticity and mid-level moisture to wring out a few showers and perhaps isolated thunderstorms. Otherwise expect a return to more seasonable temps as southerly low level flow finally returns with highs in the upper 70s/low 80s and lows in the 60s Looking ahead, medium range guidance is hinting at a much more powerful storm system that may move over Texas next weekend. However, confidence remains low as models continue to struggle with the evolution of the large scale pattern across the CONUS beyond Wednesday of next week. It does look likely that our active pattern continues which is great news cause many areas could really use the rain to help put a dent in the ongoing drought.

AVIATION

(00Z TAFS) Issued at 635 PM CDT Sun Apr 5 2026

Few changes to the going forecast with some small tweaks to setup timing and windshifts at area terminals. Expect VFR ceilings through the period with a shift from NNE winds to more ENE/easterly winds by mid to late Monday morning. Winds should relax after sunset this evening with gusts no longer a factor.
