KEY MESSAGES

- Slight chance for showers and thunderstorms during the afternoon hours beginning Monday through midweek, then increased chances through the second half of the week.

DISCUSSION

Issued at 1203 AM CDT Sun May 31 2026

Continued warm weather will persist through at least mid-week as a ridge of high pressure remains over the Southern Plains. High temperatures will be in the upper 80s to low 90s (with isolated spots reaching the mid-90s) and afternoon heat indices climbing to near 100. Overnight low temperatures will be in the mid to upper 70s. The high pressure over the region is relatively weak allowing for moisture to creep in giving us some partly cloudy skies during the day mostly cloudy skies at night (along with some very patchy fog potential).

Weak shortwaves moving through the ridge combined with daytime heating will lead to isolated to scattered shower and thunderstorm activity beginning on Monday. Chances will be greatest along the coast on Monday along the afternoon seabreeze. A weak boundary will approach the region from the northeast on Tuesday, which could help initiate activity across much of the region - if it is able to push into the region. This time of year, these weak boundaries from the northeast end up stalling/dissipating before reaching SE Texas, so this is certainly a possibility. If this boundary doesn't push in, then at least coastal showers/storms will be possible during the afternoon. The daily slight chance of activity will persist through the remainder of the week, but increased moisture advection at the surface thanks to southeasterly winds may lead to increased coverage.

AVIATION

(00Z TAF Issuance) Issued at 633 PM CDT Sat May 30 2026

South to southeast winds become light and variable overnight. MVFR CIGs around 1000-1500 ft may briefly develop in spots early Sunday morning. Patchy fog may also develop in spots through CIGs are anticipated to primarily drive FL changes. CIGs scatter and fog should lift after sunrise. VFR conditions and SE winds prevail throughout the daytime on Sunday.

MARINE

Issued at 1203 AM CDT Sun May 31 2026

Low seas and onshore winds (5-10kt with gusts to 15kt during the overnight hours) will persist through Tuesday. A weak boundary approaching from the northeast will help develop an easterly flow Wednesday into Thursday with wind speeds increasing to 10-15kt and seas to 3-5ft.

Isolated shower activity is possible over the coastal waters during the overnight hours beginning Monday night. The chance for daily showers and thunderstorms increase midweek through next weekend as that weak boundary approaches the region and increased southeasterly winds brings increased moisture.

Beginning midweek, we may also begin to see a moderate to high risk of strong rip currents as the persistent onshore flow continues.
