KEY MESSAGES

Issued at 1231 AM CDT Wed Sep 23 2026

- Slightly cooler but still warm air will continue funneling into our region from the northeast over the next 48 hours before we see temps increase once again for the upcoming weekend. - Upper ridging appears to give way to a longwave trough in the Tue/Wed timeframe next week bringing with it much needed rain chances along with cooler temperatures.

DISCUSSION

Issued at 1231 AM CDT Wed Sep 23 2026

It was another day of triple digit heat for much of the region on Monday with temperatures aided by compressional warming ahead of a very weak cold front. Locations that saw triple digit heat included Natchitoches and Shreveport, Louisiana as well as Mount Pleasant, Tyler and Longview Texas. The city of Tyler tied their record high temperature of 100 degrees last reached in 2005 for the date. NBM MOS did back off temperatures a few degrees for Wed but there is another weak sfc boundary that will be backdooring itself into SW AR and SE OK that could help to generate isolated storms today across our northern third. Eventually, that drier air will funnel into our region from the Ouachitas late in the day Wed, into the I-20 Corridor Wed Evng and through the remainder of our region during the day Thu. Our coolest night appears to be Thursday Night with low temperatures in the 60s and maybe upper 50s across the Ouachitas of SE OK and SW AR before upper ridging begins to build back into the region for the upcoming weekend.

That upper riding for the weekend into Monday of next week will result in a slight warming trend ahead of our next weather maker by the Tue/Wed timeframe in the form of a longwave trough. Have not seen the effects of a longwave trough in quite sometime across the Southern Plains/Lower Miss Valley. This trough...if it can stay as amplified as progs show...could result in pretty good rain chances Tue into Wed of next week along with somewhat cooler temperatures.

AVIATION

(06Z TAFS) Issued at 1231 AM CDT Wed Sep 23 2026

For the 23/06Z TAF period, a frontal boundary has nearly cleared all of our airspace with KLFK the only terminal still showing southerly winds. Elsewhere, winds have shifted to the NE in wake of fropa with some lingering cu/altocu and thin cirrus increasing from the west. With the drier post-frontal air in place, expect VFR conditions to prevail with the possible exception of KLFK where some patchy fog may develop early this morning before the front full clears to the south. Any post-frontal convection should be very isolated at best and confined to our northern airspace after daybreak through midday. NE winds will prevail between 5-10 kts with slightly higher gusts possible during the afternoon hours.
