DISCUSSION

Issued at 119 PM CDT Fri Aug 28 2026

Through Saturday: Drier weather and less humidity is expected tonight and Saturday as a drier airmass moves into the northern half of the CWA. Latest surface analysis had a nearly stationary dry cold front between Highway 82 and Interstate 20. Continued northwest flow aloft combined with northerly low level flow from a surface high to the north will continue to help the dry cold front drift further south into our CWA before stalling tonight. North of the cold front surface dew points will drop into the 60s and PWATS will drop below an inch and a half. The surface high will continue shifting east through Saturday resulting in a northeast to easterly wind. The large mid level ridge to our west will begin spreading back to the east over our CWA. Together these features will result in warmer temperatures Saturday but also drier conditions over most of the CWA. Low chances of afternoon convection is expected to become limited to the Interstate 59 corridor. /22/

Saturday night through next Thursday

Saturday night - Sunday:

An upper-lvl high over the Southwest & Texas will expand and progress eastward towards the Southeast. A cut-off low pressure center near Gulf states will track westward, shifting rain chances southeast into the Pine Belt into weekend, with the Interstate 59 corridor ranging from 15-30% Sunday. As the high progresses, heat indices are expected start increasing to near 100 degrees Sunday.

Monday - Thursday 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/
