- 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.

Issued at 137 AM EDT Wed Oct 21 2026

Morning fog along rivers and lakes will be possible again during the late night into early morning hours today, as cool air settles over the warm waters.

A large upper ridge to our west will gradually shift eastward during the period and surface high pressure to our north and northeast will extend into our area, keeping our weather dry through next Tuesday. We will see cool nights and pleasant afternoons with high temperatures each day not far either side of seasonal normals. We will also see low relative humidity values during the afternoon hours.

(06Z TAFS) Issued at 137 AM EDT Wed Oct 21 2026

VFR TAFs, a very low chance for river fog again this morning, but kept it out of the TAFs. Clear to mostly clear skies with light winds.
