KEY MESSAGES

- Unseasonably warm and dry weather continues Today and Tuesday

- Rain chances return to South-Central Texas by the middle of the week with more chances over the weekend

SHORT TERM

(Today through Tuesday) Issued at 1212 AM CDT Mon Mar 30 2026

Very quiet weather expected in the short term as the majority of the CONUS is dominated by zonal flow. Tonight low clouds will be filling in before dissipating by mid morning tomorrow. Expect dry weather with highs in the upper 80s to low 90s for both tomorrow and Tuesday. Lows in the low to perhaps mid 60s can be expected for tomorrow night. Low clouds will once again fill in by Tuesday morning.

LONG TERM

(Tuesday night through Sunday) Issued at 1212 AM CDT Mon Mar 30 2026

We begin to get into a more active period as a dryline that sloshes back and forth out in West TX tries to make it's way eastward into possibly Val Verde County by Tuesday evening as some Hi-res models suggest. Elsewhere, the forecast remains dry until this dryline propagates farther eastward Wednesday, helped along by an upper level trough pushing across the area. Models have come into much better agreement over the last 24 hours or so with most showing a line of scattered convection approaching the area from the northwest and moving southeast late Wednesday evening. While the possibility for a few strong to severe storms is there the timing being quite late into the overnight makes for a lack of confidence in the severe potential. We could see pockets of heavier rainfall especially if this trough slows down.

We remain warm going into Thursday as we dry out by the afternoon and get a break from precipitation. Friday looks to remain dry, however, we could see some isolated streamer showers form through the day in the continued southerly flow. This helps to pump in abundant moisture from the Gulf. We get our next taste of active weather with a cold front that pushes through most of TX and gets to us by Saturday evening. This front looks much more promising regarding both convection and rain potential as models so far have continued to be very in sync with a line of convection forming and moving across our area. At this time its still too early to get into specifics but continue to check back as things get ironed out. Once this front passes expect much cooler temps Sunday and Monday with highs in the 60s for Sunday and low 70s anticipated for Monday.

AVIATION

(06Z TAFS) Issued at 1212 AM CDT Mon Mar 30 2026

Low clouds have begun to develop and will expand throughout the region from the overnight into this morning. Ceilings will be generally lowering into the MVFR to IFR range. The persistent southerly flow should keep stratus favored over fog. Expect VFR conditions to return into this afternoon with increasing winds from the south-southeast. Gusts to around 25 kt are expected. Winds gradually subside late tonight. Anticipate for returning low clouds once again overnight into early Tuesday morning with MVFR to IFR ceilings.

FIRE WEATHER

Issued at 1212 AM CDT Mon Mar 30 2026

Breezy and warm conditions return today and Tuesday as south to southeast winds ramp up. Gusts to the 25 kt range is possible. Anticipate for some locally elevated fire weather conditions to develop this afternoon, but minimum RH values should remain of around or above 25%. Additionally, the latest fuel dryness mapping from Texas A&M forest service indicates above normal moisture for areas west of the Highway 281 corridor and of near normal moisture to the east. Minimum RH values should remain above 30% for most locations outside of the Rio Grande Plains from Tuesday and beyond as low-level moisture return increases ahead of our next wetting rain ands storm chances late Wednesday into Thursday and again this upcoming weekend.
