KEY MESSAGES

- Patchy fog is less likely Tuesday morning, with only a 20% chance.

DISCUSSION

Issued at 1214 PM CDT Mon Aug 24 2026

Sfc high pressure is centered over the Ohio Valley this afternoon, providing ample sunshine with comfortable humidity levels. Increasing scattered mid-level cloud coverage tonight combined with a subtle increase in the pressure gradient early Tuesday morning should keep any patchy fog fairly sparse. By Wednesday, temperatures will return to more seasonable with increasing humidity levels as a warm front approaches from the south. Recent runs of the GFS/EC have trended more south with the boundary that would favor an elevated complex of storms remaining focused across AR/TN during the morning hours. NBM PoPs are now lower as a result, but still peak at a 20-30% chance Wednesday evening into Wednesday night in the wake of a weak cold front on Thursday. Low chances return over the Kentucky Pennyrile Thursday afternoon, with a slight drop in humidity levels being the only relief on Friday.

More significant levels of hot temperatures and humidity build next weekend as a 594 dm southeast ridge causes height rises aloft into early next week. By next Monday, 850 mb temps will be pushing 20C which translates to highs in the mid 90s with heat index values nearing the triple digits once again.
