KEY MESSAGES

* Daily shower and storm chances will continue into the middle of the week, but the severe weather risk appears low.

* Temperatures will rebound late this week into the weekend with near normal highs in the upper 80s and low 90s.

SHORT TERM /THROUGH MONDAY NIGHT/

Issued at 138 AM EDT Sun Aug 2 2026

*** TODAY - MONDAY NIGHT ***

Patchy fog and drizzle will be possible in areas this morning with the wrap around moisture from the low pressure. Scattered rain showers will continue through this morning and afternoon as the low becomes nearly stationary overhead. The combination of overcast skies and post frontal airmass will keep maximum temperatures slightly below normal in the mid to upper 70s. There is a chance areas could see slightly warmer temperatures today if the cloud cover begins to subside. Rain chances (20-40%) continue for Monday mostly for south central KY and the Blue Grass area. A few rumbles of thunder will be possislightlyble (20% chance) tomorrow afternoon with any diurnally driven instability, but no severe threat is expected. Light winds will continue tomorrow night leading to another potential fog in areas with the added moisture from the days rain showers.

LONG TERM /TUESDAY THROUGH SATURDAY/

Issued at 138 AM EDT Sun Aug 2 2026

*** TUESDAY - SATURDAY NIGHT ***

Daily rain chances will continue through Wednesday as the cutoff low remains. The northern jet stream will eventually lift the low out of the area Wednesday into Thursday. This will allow for a more zonal flow aloft and a warmer airmass to build into the region. Temperatures will rebound to near normal by Thursday with highs in the upper 80s and low 90s heading into the weekend. Flow aloft keeps low level moisture around for the weekend, leading to humid conditions with dewpoints in the low to mid 70s. A shortwave trough disturbance is expected to keep rain showers in the area through the weekend.

AVIATION /06Z TAFS THROUGH 12Z MONDAY/

Issued at 138 AM EDT Sun Aug 2 2026

A low pressure system will spin over the region through the current forecast period, with ample low-level moisture bringing rounds of low clouds, patchy drizzle/mist, and scattered rain showers. Timing out fluctuations in categories is fairly low confidence over the next few hours, though a general downward trend toward low MVFR/IFR CIGs is expected between now and 10-12Z. MVFR VIS is also expected near area terminals, especially HNB, later this morning, as patches of mist settle into the area. By mid-morning, a gradual improvement in categories is expected as moisture mixes upward; however, this will also cause scattered showers to develop. A brief window for VFR conditions is possible during the afternoon and evening hours Sunday before CIGs fall again Sunday night. Winds will be relatively light through the forecast period, veering from southerly to northwesterly at SDF/BWG/HNB.
