.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.
