KEY MESSAGES

Updated at 255 PM EDT Sat Oct 24 2026

- Dry weather dominates the forecast period, with cool mornings and pleasant afternoons each day. Afternoon relative humidity will remain on the lower side as well.

DISCUSSION

Issued at 255 PM EDT Sat Oct 24 2026

Another pleasant Fall day has played out across the region with mostly sunny skies and temperatures in the 60s and low 70s. Guidance remains in agreement with the strength and positioning of our upper level ridge over the Ohio Valley region through mid-week. This feature will continue to influence our weather pattern for much of the next 7 days. The ridge axis will gradually shift east over the next few days while incoming shortwave trough over the Great Lake region will successfully weaken the ridge mid-week. Latest model trends keep us dry through next Friday with rain chances beginning next Sunday. Models have gradually slowed down the incoming system for next weekend that it now appears that Halloween should remain dry. This is great news for those of us excited for the holiday.

Persistence type weather forecast with lows in the 40s with non-zero chance of patchy fog development while daytime highs are in the upper 60s and lower 70s with mostly sunny skies. This pattern will support ample mixing and lower afternoon relative humidity values, but light winds should limit any meaningful fire weather concerns for now.

AVIATION

(18Z TAFS) Issued at 103 PM EDT Sat Oct 24 2026

VFR conditions forecast throughout the period. Winds will be generally light and variable under a strong surface high pressure. A non-zero chance for patchy fog overnight, but left it out of the TAF given the low end chance.
