KEY MESSAGES

* Dry and pleasant conditions are expected to continue through Wednesday morning.

* Warmer temperatures (upper 80s) and chances for showers and storms return Wednesday and Thursday.

SHORT TERM /THROUGH TUESDAY NIGHT/

Issued at 318 PM EDT Mon Aug 24 2026

It's a pleasant late-August afternoon over central Kentucky and southern Indiana as surface high pressure and northwesterly flow aloft are keeping the region mild and dry, with very comfortable temperatures in the upper 70s/low 80s and dew points in the upper 50s/low 60s. This stretch of nice weather will continue through at least Tuesday night as the area of high pressure remains overhead, but does slowly drift eastward over time.

Current mid-level cloud cover will clear out after sunset, with temperatures in the upper 50s/low 60s forecast. Patchy fog will again be possible tonight, especially in river valleys, dissipating after sunrise on Tuesday. Conditions on Tuesday will be similar to today, being slightly warmer across the area with highs in the low to mid 80s. For Tuesday night, expect lows to again be in the upper 50s/low 60s.

LONG TERM /WEDNESDAY THROUGH MONDAY/

Issued at 318 PM EDT Mon Aug 24 2026

As we move into the mid-week period, fairly strong ridging will continue to build and become more broad with time. A downstream trough axis will swing through the region late Wednesday and could fire off a few showers and storms. PWATs will increase to around 1.8 inches, but model soundings show very weak shear, and rather poor lapse rates, despite ample instability. For now, the highest chances of storms looks to across southern Kentucky. Highs on Wednesday will be in the upper 80s with lows in the upper 60s.

Western CONUS ridging will hold sway on Thursday with downstream troughing across eastern US. A fairly strong shortwave trough axis will move east across the Great Lakes and drive another frontal boundary through the region. There may some slightly better convergence along that boundary resulting in another round of showers/storms moving through the region. Highs on Thursday will be in the upper 80s to around 90 with lows in the mid 60s.

Behind the frontal passage, a dry period of weather is expected for the late week and into the weekend. The upper trough axis over the region is forecast to move off to the east while mid-level height rises push east into Ohio Valley from the Plains. This will result in temperatures slightly warming through the weekend, though deep moisture will remain south/southwest of the region, so humidity values will not be bad. Highs on Friday will be in the upper 80s with highs Saturday through Monday will be in the lower 90s, with overnight lows in the upper 60s to around 70.

AVIATION /00Z TAFS THROUGH 06Z WEDNESDAY/

Issued at 732 PM EDT Mon Aug 24 2026

VFR conditions are expected for the entire TAF period. High level clouds will continue moving in from the NW overnight, but ceilings will remain well within VFR conditions. Winds will continue to be light to calm overnight as well. Patchy fog potential is too low to include in the TAF. So, mostly clear skies with a light ENE wind prevails tomorrow with VFR conditions expected.
