DISCUSSION

(This afternoon through next Wednesday) Issued at 1106 AM CDT Thu Aug 6 2026

Recent satellite obs show an advancing outflow boundary beginning to stall across far NE AR, MO bootheel and NW TN. Behind the boundary NE winds and slightly cooler, but more humid conditions provide no real relief from summer heat. A transient shower could form along or behind this boundary later this afternoon, but widespread coverage or rainfall is expected.

The persistent ridge across Central CONUS will continue ushering in warmer temps over the weekend. Combined with southerly flow drawing more moisture into the area swampy conditions will return through the weekend. A Heat Advisory is in effect in the MS River Delta for Friday afternoon, and further heat products into the weekend and next week will be on the table.

Rain chances over the weekend could help limit some of the heat. An upper level trough in phase with a weak short wave should help drive PoPs as it gets squeezed between two high pressures systems sieging the FA. After this weak system and PoPs look to be limited to any afternoon summer-time popups.
