.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.
