KEY MESSAGES

- Rain chances decrease into the weekend, with rain and storms mostly confined to Pine Belt and Interstate 59 corridor.

- Dangerous heat stress may return across the forecast area late this weekend into next week.

MESOSCALE UPDATE

Issued at 956 PM CDT Thu Aug 27 2026

Updated short-term weather elements with the latest guidance. No significant changes were needed, apart from reducing patchy fog inclusion. Late afternoon satellite observations showed sufficient clearing to indicate erosion of boundary layer humidity. Cannot rule out patchy shallow fog. /NF/

DISCUSSION

Issued at 142 PM CDT Thu Aug 27 2026

Tonight through next Wednesday

Tonight - Sunday:

Rain and storm chances will continue to decrease for majority of the CWA as the frontal boundary traverse south this afternoon. Once the front stalls near the Gulf coastline, evening rain chances will become confined to the Pine Belt through the early evening. The trough will lift northward Friday, allowing an upper-lvl high over the Southwest & Texas to gradually move eastward towards the Southeast. Patchy fog development may be possible pre-sunrise Friday morning. A cut-off low pressure near Gulf states will track westwards, shifting rain chances southeast into the Pine Belt into weekend, with the Interstate 59 corridor ranging from 15-30% Friday through Sunday. As the high progresses, heat indices are expected start increasing to near 100 degrees by Sunday.

Monday - Wednesday Night:

The aforementioned high will settle over the Southeast CONUS around Tuesday, lingering through the rest of the week. As a result, dangerous heat concerns are expected to return mid-week as heat indices peak near or in excess of 105F. HWO graphics may be needed but timing is still several days aways. Another low pressure will traverse around the ridge, bring deep moisture and storm chances southeast of I-20 and along HWY 84 through the forecast period. /SW/

AVIATION

(00Z TAFS) Issued at 956 PM CDT Thu Aug 27 2026

VFR conditions expected to prevail at the TAF sites through the period. While patchy shallow BR cannot be ruled out around 12Z Friday, confidence in MVFR or lower impacts is not high enough to include in TAFs. /NF/
