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/DC/
