KEY MESSAGES

- The heat and humidity will continue today with peak afternoon temperatures rising into the low to mid 90s (31-36 Celsius) with peak heat indices near 103-107 (39-42 Celsius).

- Moderate to high risk of rip currents this weekend, likely continuing into portions of next week with elevated high tides.

- Scattered showers and thunderstorms possible daily through at least midweek. Locally heavy rainfall leading to urban and small stream flooding will be possible with any isolated strong storms.

DISCUSSION

Issued at 1259 AM CDT Sun Jun 14 2026

Hot weather is anticipated for today as ridging and above-normal heights remain overhead through the first half of today. Models still have midlevel heights around 591-592 dam overtop the area with onshore winds still progged to bring robust moisture & WAA during the daytime. This surging moisture from the Gulf will increase rain chances as well. We'll likely see isolated/scattered showers early in the morning over the Gulf/coastline, increasing in coverage and spreading inland by the afternoon hours as storms also develop. Many spots are anticipated to see some form of precipitation, which should mostly limit the heat stress during the afternoon. However, any areas that don't get rainfall, or receive very little, should still see some pretty hot conditions. Highs are still forecasted to reach the upper 80s/mid 90s (31-36 Celsius) with heat indicies around 103-107 DegF (39-42 Celsius). The greater coverage in showers should cool the area sufficiently to avoid the need for any heat products, though it would still be worth practicing heat safety regardless. Make sure to stay hydrated and cool off indoors if needed.

There should be a brief lull in rainfall tonight, then rain chances will start to increase after midnight into the early morning hours of Monday as a cold front approaches SE Texas. PWs are progged to surge to 2.1-2.4 inches ahead of the front from a weak disturbance pushing north up long the TX/Mex coast. Forecast soundings still show saturated conditions, skinny CAPE profiles, and a deep warm cloud layer, all of which signal the potential for heavy rainfall. The cold front should enter SE Texas on Monday, stalling out over the area and lingering there through Tuesday. WPC now has SE Texas under Slight (Level 2/4) to Marginal (Level 1/4) Risk of Excessive Rainfall Sunday night through Tuesday, decreasing to a Marginal Risk (Level 1/4) on Wednesday as the frontal boundary lifts north. Rainfall totals over this period are forecasted to range from around 1-3 inches though isolated higher amounts of 4-6 inches will be possible. These heavier amounts over a short period could result in flash flooding, especially if this rainfall occurs over urban/low lying areas. Make sure to have multiple ways of receiving warnings and remain weather aware!

Daily showers continue through the end of the work week as a weak low makes it's way up the Texas coast. Temperatures will also be on the rise once again as ridging builds over the Gulf. Hot weather and heat indicies in the triple digits are poised to return as well, so continue practicing heat safety!

If you have any beach plans, make sure to watch out for rip currents these next several days. Swim near a lifeguard, if possible, and be sure to avoid swimming near any rocks, jetties, and piers where rip currents frequently occur. Above normal tides and some isolated minor coastal flooding will also be possible along the coastline at high tide as well.

AVIATION

(00Z TAF Issuance) Issued at 620 PM CDT Sat Jun 13 2026

Elevated SE winds of around 10KT and gusts up to 20KT continue at most TAF sites. Gusts should drop off and winds gradually decrease later this evening. An MVFR cloud deck moves in from the east, lowering CIGS across the CWA. Most TAF sites are expected to experience these MVFR CIGS early tomorrow morning through late morning, though confidence is lower for sites along and south of I-10. CIGS are expected to improve to VFR by late morning across the CWA. A frontal system approaches the region tomorrow, bringing increased chances for thunderstorms starting tomorrow afternoon. With this, winds will increase to around 10KT with occasional gusts around 20KT and veer to the SSE.

MARINE

Issued at 1259 AM CDT Sun Jun 14 2026

Light to occasionally moderate onshore winds and seas of 3 to 6 feet are expected through early next week. Caution flags and advisories are in effect overnight through the early morning for gusts near 25 knots and seas of 7 ft offshore. Conditions should improve by the mid morning hours. Scattered showers and storms become more widespread overnight through Monday as a weak front stalls out over SE Texas. A passing disturbance along the Texas coast will bring moderate to strong onshore winds and higher seas early Wednesday through Friday afternoon. Continued onshore flow will result in a moderate to high risk of rip currents with elevated tides around 3.1- 3.6 ft (MLLW).
