KEY MESSAGES

Issued at 104 PM CDT Tue Jul 28 2026

- The Heat Advisory has been extended through 8 PM Wednesday night areawide as heat indices again climb above 105 degrees. Continue to practice heat safety, hydrating well, limiting outdoor exposure, and having access to air conditioning.

- Hot, mostly dry conditions will continue, with afternoon highs in the upper 90s for most sites through the end of the week.

- Increasing chances of showers and storms across Arkansas and portions of north Louisiana may provide some brief relief from the heat tomorrow and Thursday.

DISCUSSION

Issued at 104 PM CDT Tue Jul 28 2026

Our stubborn high pressure over the Desert Southwest and associated area of ridging will keep the ArkLaTex mostly dry and very hot for at least another day, thus have extended our Heat Advisory another 24 hours, now in effect through 8 PM Wednesday evening.

The eastern extent of the ridging will keep the Four State Region firmly in its grip overnight, keeping quiet and muggy conditions in play while lows drop into the middle to upper 70s areawide. Tomorrow will see much of the same for the majority of the region as highs quickly climb back into the upper 90s to lower 100s while dew points remain muggy enough to push heat indices back above 105 through the afternoon. Continue to practice heat safety techniques, limiting outdoor exposure and exertion, wearing light-colored, loose-fitting clothing, and keeping hydrated.

Our northeastern zones may begin to be affected by the upcoming pattern shift as soon as tomorrow afternoon, however. The high pressure will start to retrograde westward over the Four Corners region, opening the door for troughing to slide a weak boundary down the Mississippi Valley, kicking up showers and storms across Arkansas. If the ridging relents adequately in time, some of these showers may manage to push into our southwest Arkansas zones during the afternoon hours tomorrow, providing some relief from the heat.

The pattern shift which begins tomorrow will attempt to continue through the end of the week and into the weekend, opening the door for increasing chances of storms across our eastern zones Thursday, receding somewhat Friday and returning into the weekend as a shortwave swings a frontal boundary south. Coverage of impacts looks limited at best, based on the latest model runs. Thus our northeastern zones may enjoy some relief from the heat but areas south and west will still likely see heat indices above 100 through Saturday before temperatures finally drop out of the upper 90s Sunday, warming again going into early next week. Scattered chances of afternoon thunderstorms will persist through the end of this extended forecast period.

AVIATION

(18Z TAFS) Issued at 104 PM CDT Tue Jul 28 2026

For THE 28/18Z TAF period, VFR conditions are expected throughout the period as diurnal trends continue to dictate a daytime cu field expanding this afternoon between 4-5Kft followed by mostly SKC overnight as the cu field diminishes. Some thin cirrus will also be increasing this afternoon ahead of a weak frontal boundary north of our airspace. Otherwise, look for SW winds between 5-10 mph this afternoon before decreasing slightly overnight. Expect another repeat performance on Wednesday with a cu field developing around 15Z as SW winds also begin to increase slightly ahead of the front with any associated convection likely holding off until just beyond this TAF period. /19/
