KEY MESSAGES

Issued at 1216 AM CDT Sat Aug 29 2026

- Above normal temperatures, minus the heat headlines will persist for the next several days with little if any rain.

- A few sites in deep east Texas have been around 106 briefly, but keep in mind this is where rain was missed last time.

- A gradual warming trend unfolds as we continue with upper 90s and increasing humidity, making it feel hotter and thus more widespread heat headlines by midweek as we continue mostly dry.

DISCUSSION

Issued at 1216 AM CDT Sat Aug 29 2026

Another nice day in the books with a few temps still in the triple digit range, all of which occurred in east Texas, where soil temps did not see much cooling rainfall. The NE winds started varying E to SE at times with our soundings split yesterday showing SE flow in the lowest levels at 18Z and then back to all NE low level flow by 29/00Z. So this surface high is in flux over the Ohio River Valley and mid Atlantic states at 1024mb at this hour. Of course pressure goes up for the cooler night time and falls off a bit with heating. This is why we do most balloon flights at daybreak and sunset to see these variations.

Likewise, cold fronts move better at night as heating makes the ride a little slower being bumpy. Same on a plane, turbulence is worst late day than early. The recent cool front that arrived Thursday is loosing identity for us, but is still draped over our southern tier of counties and parishes. Friday saw a weakness with a few showers and isolated storms east of I-49 in the NW flow aloft. Today the models and the WPC paint some light QPF over deep east TX with a slight PoP in place for this afternoon near the front, which will amble back northward. As time goes on, the SE winds south of the front will power back through the slightly drier air, with more humid tropical air off of the Gulf. So, while highs will average in the upper 90s and lows will bump back to mid and upper 70s, responding to these southerly dew points, the heat index will be rising. Because that's how "relative" humidity is calculated, and a rising dew point means higher minimum RHs in the afternoons to come. In response, the daily max heat indices will soon elevate back above 105 for all of us during next week.

Any appreciable rain chances will creep up on the sea breeze, but overall the drought is back in action. Not much will change this week as the upper heat ridge extends back to the east this week. The upper weakness along the Gulf coast will be the check valve for us keeping our heights aloft from soaring. So really the slow moistening trend will be what really makes it start to feel hotter. All that humidity returning makes it hard for perspiration to evaporate, thus the rapid sweat is soon to return. So keep the plan of working outside early and late and avoid the hottest part of the days each afternoon.

And we are still watching what exactly the remnants of T.S. Dolly will do, now riding over the Windward's and N of Puerto Rico toward the Bahamas on the NHC official track. That arriving upper ridge moving from AZ/NM to 596dam over the Ohio River valley will steer the wave into the very warm waters of the Gulf. The latest GFS bounces a weak surface low and upper weakness along the Gulf coast over the Labor Day weekend. This is what happened with Bertha, limiting the chance to circulate over open waters, keeping intensity at bay so to speak. /24/

AVIATION

(06Z TAFS) Issued at 1216 AM CDT Sat Aug 29 2026

VFR conditions will continue through the 29/06Z TAF period. Scattered areas of AC cigs have developed over portions of E TX along/just S of the I-20 corridor, and should persist overnight before diminishing around mid-morning. Afterwards, a scattered cu field will develop areawide, with isolated convection possible this afternoon across portions of Wrn LA and adjacent sections of E TX before diminishing by/shortly after 00Z Sunday. However, low confidence precludes VCTS/VCSH mention for the SHV/E TX terminals attm. Some elevated cu/low AC should again linger this evening across this area of E TX and adjacent WCntrl LA. Lt/Vrb winds overnight will become mostly Vrb around 5kts after 15Z. /15/
