KEY MESSAGES

Updated at 734 AM EDT Thu Oct 22 2026

- Early morning patchy fog potential continues near rivers and lakes.

- 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 129 AM EDT Thu Oct 22 2026

Patchy early morning fog will be possible again today, but it should be mainly near rivers and lakes.

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 into early next week. Models suggest the upper ridge may break down and some models have a front approaching by mid week, but even then moisture looks very limited and thus we have a dry forecast for the entire period through Wednesday.

For the entire period we can expect 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.
