KEY MESSAGES

Issued at 1251 AM CDT Tue Jul 28 2026

- Hazardous heat will continue in earnest through Wednesday with temperature maximums likely in the upper 90s/lower 100s and mostly dry conditions.

- A pattern change begins by Thursday into the weekend, yielding a return to near-normal summertime heat (mid-90s) and higher chances of rain.

- A summertime frontal boundary is expected by the weekend, delivering the potential for cooler-than-normal temperatures and maintaining chances of rain across the Ark-La-Tex.

DISCUSSION

Issued at 1251 AM CDT Tue Jul 28 2026

The next 48 hours will be the hottest time period of the week for the Four State Region as the ridge axis stays in place across the southern Great Plains. One of the main determinants of the heat hazard intensity involves the amount of mixing that can occur from southeasterly winds, and at the moment those winds are expected to remain light at just 5mph. With little reprieve from the heat Heat hazard product issuance is likely to continue through Wednesday at minimum. Medium-range guidance continues to suggest ridging finally starting to shift westward by the end of the week and the end of the month. Synoptic-scale flow aloft will gain more of a meridional orientation as a troughing pattern takes shape between Atlantic ridging further to our east and Intermountain ridging to our west later this week. Until then, this meridional flow will influence a stationary front that will sit across the lower Mississippi River Valley, introducing the first notable chances of rain by Thursday afternoon. A return to normal summertime heat (mid-90s) is likely as a result by this time with a coinciding increase in the potential for productive rounds of convection to form in the afternoons with daytime heating. Long- range guidance continues to suggest an increasing chance of a summertime frontal boundary that delivers even cooler air by Saturday (potential for temperatures in the lower 90s) and higher rain chances through the weekend (especially for eastern zones.

Until then, fairly light southerly winds will still not offer much relief and dew points are expected to remain mostly in the upper 60s/low-to-mid 70s. Heat indices will range above 105 degrees as a result, and hazardous heat will be impactful for all groups of people, not just heat-sensitive groups. 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.

AVIATION

(12Z TAFS) Issued at 601 AM CDT Tue Jul 28 2026

VFR conditions currently prevailing across our airspace but IR Imagery is showing MVFR cloud cover just west of the LFK and TYR terminals moving northeast. For the 12z TAF package...did TEMPO MVFR ceilings for a few hours this morning at the LFK and TYR terminals but kept all other terminals with a SCT cu field during the day. Any cu should have dissipated by 00z this evening with only some high thin cirrus possible overnight.
