.DISCUSSION...
Issued at 228 PM EDT Fri Oct 23 2026

Largely a persistence forecast as we remain on the eastern periphery 
of an anomalous ridge axis centered in vicinity of the Ozarks 
through the weekend. The ridge will slowly progress eastward, 
becoming increasingly centered over the forecast area by early to 
mid next week. However, the northern extent of the ridging will be 
somewhat suppressed by bouts of energy, leading to fairly steady 
temperature trends through the period.

High pressure and associated subsidence will continue to promote 
mostly clear skies and dry weather. The dry air will keep mornings
cool and afternoons pleasant. Some patchy valley fog will be 
possible each morning, especially near rivers and lakes. Light 
winds will hinder any notable fire weather concerns despite low 
afternoon RHs.
