.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.

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.
