.DISCUSSION...
Issued at 130 PM EST Tue Nov 18 2025

Today`s disturbance will continue to move eastward tonight bringing
an end to the light rain showers and possibly a bit of drizzle
especially south of US-30 by early morning Wednesday with some
drier air pushing southward into the area this evening.
However, with a more zonal flow in the wake of this system
cloudy to mostly cloudy conditions should continue over the next
several days. This will also keep high temperatures pretty
stable and seasonable through the beginning of next week with
highs in the upper 40s to mid 50s.

Another system originating from Baja of California will move
northeastward across Texas into the Ohio River Valley. This will
increase chances of rain showers for our area beginning Thursday
afternoon into  There is a bit uncertainty to the exact track
of the system but latest guidance does bring it south of our
CWA. This would help to keep precipitation in the liquid form
and limit the rainfall amounts. So will need to keep an eye on
the exact track as the further south it goes the less rainfall
we would see.

Looking well ahead for late next week there are indications of
a much colder airmass to move into the area for the holiday.
This may include some snowfall however with more than a week
away will need to continue to monitor for that potential in the
coming days.

.AVIATION /00Z TAFS THROUGH 00Z THURSDAY/...
Issued at 631 PM EST Tue Nov 18 2025

Cigs are persisting right on the line on low end MVFR and high
end IFR (900 to 1000 ft) at both locations. E to NE flow,
abundant low level moisture and an inversion around 1000 ft all
suggest little improvement overnight, with potential for cigs to
drop down a bit more (likely staying away from LIFR, but will
need to keep an eye on things).

A bit of drizzle was still lingering near KFWA, but for now have
removed any mention of precip. Not out of the question that some
drizzle may need to be added as weak lift persists.

Conditions may slowly improve through Wednesday, but have slowed
down the timing of a return to more solid MVFR conditions.
