KEY MESSAGES

Issued at 1230 AM CDT Wed Sep 9 2026

- Heat headlines persist today as the expansive upper ridge maintains a stranglehold on much of the southern CONUS.

- A gradual weakening of the upper ridge is expected by the end of this week, making way for a trough to drop south with rain chances increasing areawide on Friday.

- The ridge will eventually regain its footing across much of the SECONUS by late weekend, limiting daily convection to diurnally driven activity mainly during peak heating hours.

DISCUSSION

Issued at 1230 AM CDT Wed Sep 9 2026

The late summer doldrums continue uninterrupted for the time being as the upper ridge maintains an expansive footprint across a large chunk of the southern CONUS. Therefore, heat advisory headlines remain with us for yet another day with further issuances possible into Thursday. Little in the way of heat relief is expected today in terms of convection, but those chances do begin to increase as we move into Thursday and especially Friday.

This slight pattern shift will begin with a weakening of the upper ridge on Thursday as it breaks off, opening the door for a weak upper trough to drop south into the region through the end of the week. As a result, we should at least expect a slight drop-off in high temperatures for Friday with low-end rain chances increasing areawide. Although not everyone can count on seeing any rainfall, Friday is likely to be our best chance over the next 7 days with decent coverage, especially during the afternoon through the early evening hours.

Unfortunately, it appears that the ridge will gradually build back strong as we move later in the weekend. That will begin to greatly limit our rain chances once again while pushing temperatures back higher through early next week. Any convection will generally be diurnally driven for much of next week before early indications of the upper ridge beginning to retrograde farther out to the west by the end of next week. That would certainly be a welcome change and possibly our first real sign of the changing seasons to come if it indeed comes to fruition. /19/

AVIATION

(12Z TAFS) Issued at 611 AM CDT Wed Sep 9 2026

For the ArkLaTex terminals, a light S/SE wind this morning under fair skies. S/SE sfc winds will prevail 5-10KT for today with little if any convection expected this late afternoon. Winds aloft are light as well with E/SE at 10-20KT for climb, all FLs and abv. This drier pattern lingers through midweek, but an uptick in convection is expected by Friday as weak cool front pools all the moisture over our area for a few days through next weekend. /24/
