.SHORT TERM...(This evening through Saturday night)
Issued at 452 PM EDT FRI MAY 22 2026

A broad upper trough is over the western and central CONUS late
today, while an embedded northeastward moving shortwave trough is
over the Ozarks. The shortwave is supporting a surface low in the
vicinity of western KY/West TN, traveling northeast along a warm
front over the Ohio Valley. Extensive showers and a few
thunderstorms have been occurring over our area ahead of the
system today. The clouds and precip have held temperatures back
from where they otherwise could have been, which has limited our
instability, in turn keeping convection more tame than it could
have been up to this point. There is still some decent directional
and speed shear in the lowest levels, and the severe wx threat
won`t be completely ruled out. However, with peak heating about to
pass, the threat of severe wx would seem to be waning. Convection
has been persistent in some places and the CAPE profile is
generally thin, allowing for some localized rainfall amounts
probably exceeding an inch. With a Flood Watch already in place in
our far northern counties, will let it ride just in case training
cells were to occur there this evening.

The surface low and shortwave trough will pass to our north
tonight and our limited instability will further wane. This will
allow for an overall reduction in precip which lasts into Saturday
morning. The lack of activity going into the day should allow for
a bit more heating (compared to Friday). The system`s very weak
cold front will be approaching from the northwest and is expected
to help generate more showers/thunderstorms in an uncapped
atmosphere ahead of it, especially in the afternoon. With
weakening instability on Saturday night, activity should again
decline.

.LONG TERM...(Sunday through Friday)
Issued at 452 PM EDT FRI MAY 22 2026

The main belt of stronger flow aloft will retreat to the north
early in the week and the aforementioned front from the short
term section will lose momentum. It is expected to stall in our
area and allow for a daily threat of showers/thunderstorms. An
upper trough should deepen over the northeast CONUS at the end of
the week, which could allow for a southward push of drier air
finally making it here. The POP is lower on Friday to allow for
this possibility.

.AVIATION...(For the 18Z TAFS through 18Z Saturday afternoon)
ISSUED AT 113 PM EDT FRI MAY 22 2026

Widely ranging conditions were present shortly before TAF
issuance. Most places were LIFR to MVFR, but there were some
pockets of VFR. Light rain was widespread. Modest improvement is
expected this afternoon, with a bit more VFR expected as
generalized visibility comes up a bit. However, conditions will
remain variable through the period, with showers at times.

.JKL WATCHES/WARNINGS/ADVISORIES...
Flood Watch through Saturday morning for KYZ044-050>052-104.
