.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 /18Z TAFS THROUGH 18Z WEDNESDAY/...
Issued at 1256 PM EST Tue Nov 18 2025

Surface low pressure across MO this aftn will push east through
the lower OH valley overnight as high pressure settles into the
gtlks region by sunrise Wednesday. A warm front ahead of the
low pressure system is situ south of the fcst area. The latest
radar trends have shown an area of rain showers clipping the
KFWA terminal with vsbys dropping at times to MVFR. The fcst
sounding for KFWA shows a rather strong inversion through the
night so low cigs are anticipated there while KSBN should not be
impacted as much with regard to persistent low cigs. The rain
should be east of the area by 06Z.
