- Limited Threat of dangerous heat stress continues today.

DISCUSSION

Issued at 238 AM CDT Tue Sep 22 2026

Today through next Monday...Weak troughing will exist across mainly far eastern portions of the forecast area, as high pressure aloft begins building into the region from the west. At the surface, a frontal boundary will stall through or just south of the region by the end of the day. This, combined with daytime heating in the middle 90s, will again result in isolated to scattered showers and storms developing across areas mainly along and southeast of the Natchez Trace Parkway this afternoon. Heavy downpours and frequent lightning will be possible with storms, with gusty winds possible. As such there is a Marginal Risk for isolated severe storms capable of producing damaging wind gusts over some central and eastern portions of the CWA this afternoon.

With high pressure aloft and at the surface becoming more prevalent across the region through the remainder of the forecast period, rain chances essentially dwindle to nil. However in the aforementioned frontal boundary's wake, drier air and less hot conditions will exist across the forecast area for the remainder of the week and into the weekend. As highs Wednesday range from the low to middle 90s, come late week and into the weekend they'll range from the upper 80s to lower 90s. Lows will likewise follow suit as they'll range from the upper 60s and lower 70s Wednesday morning. Then cooling into the low to middle 60s late in the week and through the weekend. /OAJ/
