KEY MESSAGES

Updated at 133 AM CDT Sat Apr 25 2026

- Moderate to Major Heat Risk beginning this weekend for the inland Coastal Plains to the Brush Country through next week

- Marginal threat for severe storms today in the western Brush Country (1 out of 5)

- Coastal flooding conditions possible through the weekend.

DISCUSSION

Issued at 133 AM CDT Sat Apr 25 2026

A couple of models continue to hint at the possibility of storms developing along the dryline located in West Texas extending to Mexico. With decent moisture available, moderate to strong instability and some passing shortwave energy moving across the area showers and storms will be possible. Some of these storms will have the possibility to become severe though SPC has backed most of the Brush Country out of the Marginal Risk except for the western portions. However, due to the environment large to very large hail will be possible with any storm that develops. We will keep a close eye on how things progress during the day tomorrow.

Otherwise, above normal temperature can be expected through mid-next week. WPC has the region portions of the Coastal Bend to the Brush Country in Moderate heat stress conditions for today and Major heat stress conditions Monday through Wednesday. Heat indices through Sunday will generally range from 100-105 with indices approaching 110 degrees Monday and Tuesday. Make sure to practice heat safety. Take frequent breaks and remember to stay hydrated, check those backseats, and avoid long exposure in these temperatures. For more information be sure to check out weather.gov/heatsafety.

Will continue to monitor the risk for coastal flooding, though tide levels look to remain under 1.5 ft MSL today. Periods also look to remain under 8 seconds (6 seconds) which likely means wave run-up should finally be done. Will monitor this over the next cycle for any changes.

AVIATION

(06Z TAFS) Issued at 133 AM CDT Sat Apr 25 2026

CIGS have dropped quickly late tonight with IFR conditions noted for eastern sites. Have tempo LIFR conditions for each of these sites. Expect COT and LRD to likely drop to IFR CIGS later in the night as well. Some VIS restrictions are also possible for eastern sites, but should be mainly MVFR to IFR. Will be a slightly slower improvement in conditions during the day Saturday, but should still be VFR by mid-day for all sites. Saturday night looks similar to tonight, so have noted IFR CIGS by the end of the TAF period.

MARINE

Issued at 133 AM CDT Sat Apr 25 2026

A gentle to moderate onshore flow (BF 3-4) is expected to become a Fresh breeze (BF 5) Wednesday ahead of an approaching cold front late next workweek. Very low rain chances throughout the forecast period.

FIRE WEATHER

Issued at 133 AM CDT Sat Apr 25 2026

Expect fire weather concerns to remain low due to RH levels generally in the 40-50% over inland locations. Around mid-week RH values will drop to around 30% mid-week as temperatures soar into the triple digits. 20 ft winds will be less than 10 mph and above normal fuel moisture are expected to limit fire weather concerns. As temperatures rise over the coming days, heat indices starting this weekend will generally range from 100-105 degrees with indices approaching 110 degrees Monday and Tuesday. Make sure to practice heat safety. Take frequent breaks and remember to stay hydrated, check those backseats, and avoid long exposure in these temperatures. For more information be sure to check out weather.gov/heatsafety.
