KEY MESSAGES

Issued at 1141 AM CDT Thu Sep 17 2026

- High temperatures in the middle to upper 90s will continue through the week and into the weekend, with dry conditions expected throughout.

- Slight rainfall chances return early next week, but confidence and coverage remain unclear at this point.

- Minor relief from the heat may be possible next week, primarily in the form of overnight lows in the 60s across our northern zones.

DISCUSSION

Issued at 1141 AM CDT Thu Sep 17 2026

The upper-level high that has kept temperatures high will continue shifting westward from where it was previously stuck over the Southeast. The center of this high moving over the region will effectively cut off most attempts of rain developing through the remainder of the week and this weekend. The high will keep temperatures in the mid to upper 90s but will also be ushering some drier air, which will help keep heat indices lower than they have been in recent days. Even without heat products in place, the prolonged hot and dry conditions will continue to worsen drought and fire weather concerns the longer we go without meaningful rain.

The opening for a cold front and some rain on Monday look a bit more uncertain compared to previous forecasts. The GFS and Euro have lined up more on the 6z run: suggesting that high pressure will restrengthen over the Ark-La-Tx and keep the influence of the upper- level trough to the north mostly at bay. This morning's NBM is still painting in some slight chance PoPs during the day Monday, but are more scattered and largely limited to western and northern zones. WPC's D1-7 QPF doesn't inspire much more confidence with accumulations of basically 0. While this isn't what we want to be hearing, there is still time for models to change between now and next week.

After Tuesday, long-range model solutions return to a warm and dry regime, with temperatures back into the mid and upper 90s.
