KEY MESSAGES

Issued at 1242 AM CDT Thu Jul 23 2026

- Drier post-frontal air will be displaced by some moist easterly surface winds from Tropical Storm Bertha across Deep East Texas, prompting issuance of a new Heat Advisory for this area.

- Slightly cooler air and some isolated rain chances today (for eastern parishes) will offer a brief return to near-normal summertime heat (mid-to-upper 90s) through the end of the week into the weekend.

- Hazardous heat returns by early next week with increased potential of more temperature maximums in the lower 100s.

DISCUSSION

Issued at 1242 AM CDT Thu Jul 23 2026

Ridging will continue as the primary driver of weather conditions through the next week across the Four State Region with some brief variations as it meanders and changes in strength aloft. As Tropical Storm Bertha continues shifting west along the Gulf Coast it will maintain easterly winds across the Ark-La-Tex, quickly reintroducing the 70-degree isodrosotherm and setting the stage for hazardous heat to linger as Gulf moisture re-moistens the atmospheric column. Some isolated showers and thunderstorms could still form by this afternoon as a result, but they will be the main windows of any rain chances in the next seven days as the Day 1-7 WPC QPF values suggest most likely rainfall amounts of less than 0.25 inches areawide. Long-range guidance also suggests that ridging will build back eastward from the Southern Great Plains to reintroduce hazardous heat potential through most of the rest of the month, keeping temperature maximums above average in the lower 100s.

With dew points expected to remain mostly in the low-to-mid 70s through this time and heat indices ranging at 105-108 degrees, hazardous heat will be impactful for all groups of people and not just heat-sensitive groups today (especially across Deep East Texas). Precautions and awareness are encouraged to continue now against the elevated potential for heat illnesses. This includes (and is not limited to) altering outdoor plans, taking frequent breaks if you must be outside, checking the backseat of your vehicle, and knowing the signs and symptoms of heat exhaustion in addition to heat stroke. /16/

AVIATION

(06Z TAFS) Issued at 1242 AM CDT Thu Jul 23 2026

For the 23/06Z TAFs, mostly clear skies overnight will begin to fill in by daybreak, lowering to MVFR north and east as well as KLFK and remaining lower VFR elsewhere across east Texas. Patchy mist will be possible across our southern airspace. Conditions will improve by mid-morning, before a chance of scattered showers and thunderstorms arrives from the southeast. Impacts to terminals will depend on how far north this rain pushes, possibly arriving at KMLU and KLFK during the afternoon, but confidence does not merit including in prevailing wx at this time. Northeast winds of 5 to 10 kts overnight will become easterly during the daylight hours, increasing to 10 to 15 kts with gusts of up to 25 kts possible.
