KEY MESSAGES

- High pressure supports cool early autumn weather for the start of the week.

- Warmer temperatures return from the middle to the end of the week, along with our next reasonable shot at seeing some rain.

UPDATE

Issued at 725 AM EDT MON SEP 28 2026

No significant changes were made to the forecast with mainly just the inclusion of the latest obs and trends for the T/Td/Sky grids. These minor adjustments have been sent to the NDFD and web servers along with a freshening of the zones.

LONG TERM

(Tuesday night through Sunday) Issued at 345 AM EDT MON SEP 28 2026

Not too many changes to the forecast for this period. Confidence remains high that high pressure centered over the Ohio Valley at the start of the period will continue to keep us dry until Thursday or Friday. Confidence is also high that we will be well into the warming trend at the start of the period with highs increasing daily until the 80s return around Wednesday. The 80s will stick around until the weekend when highs should start to gradually drop down closer to normal for this time of year.

Confidence remains lower for how our rain chances will evolve late next week into the weekend. Model guidance continues the trend of slightly slowing down the onset of PoPs to Friday evening and peaking around the Sunday to Monday timeframe. Ensemble probabilties for seeing >.1" of rain Saturday through Monday remain on the higher end at 60-75%. The largest uncertainties at this time remains to be how much rain we could see, where, and when.

AVIATION

(For the 12Z TAFS through 12Z Tuesday morning) ISSUED AT 745 AM EDT MON SEP 28 2026

Valley fog will be found through the next couple of hours, resulting in localized IFR or worse conditions. However, the TAF sites are unlikely to be affected very long. Otherwise, VFR conditions and light winds will hold through the period.
