.SHORT TERM...
(Through Thursday)
Issued at 1145 PM CDT Mon Aug 31 2026

Near persistent daily trends are expected through Thursday.
Attention will somewhat turn to toward the tropical system moving
into SE TX on Tuesday and making slow progress northwestward
through Wednesday. While an isolated shower may develop across SE
OK late Wednesday or Thursday, the overall coverage will remain
very low and no meaningful rainfall is expected. The majority of
guidance does suggest temperatures trending a few degrees cooler
however dewpoints are also shown to trend upward slightly. The net
effect may see apparent temperatures warm slightly and a broader
heat advisory footprint may be needed.

.LONG TERM...
(Friday through Monday)
Issued at 1133 PM CDT Mon Aug 31 2026

The weather pattern shows no obvious sign of large scale changes
through the upcoming weekend. Temperatures will continue much
above normal and heat stress impacts should be anticipated for
outdoor events over the upcoming holiday weekend.
