.DISCUSSION...

After a foggy start, the day has been sunny with temperatures
warming into the 70s to around 80. Recently a few patches of
cumulus have popped up, and a couple of these cumulus clouds have
grown tall enough to become showers. Looking upstream, at least a
couple of strong thunderstorms were detected over Western Ky. For
this evening, we will continue to see development of scattered
showers and thunderstorms as a shortwave trough comes down from
the northwest. Conditions will be unstable enough for a couple of
strong to marginally severe storms. Steep low to mid level lapse
rates, dry layers near the sfc and mid levels, and favorable wbz
values indicate the potential for localized strong wind gusts and
hail. Shear looks weak, so any severe storms will be very
localized and brief. Coverage this evening is expected to be 20-40
percent. Coverage and intensity will decrease after midnight, but
there will still be some shower/storm potential as a weak surface
boundary drops across the area in the late night hours. By
daybreak Monday, lows will fall to the mid 50s. There may be a few
patches of fog around daybreak, but not as much as we saw this
morning.

Our new forecast for Monday will be dry. The latest models show
high pressure pushing in from the north and shutting off the rain
potential. Skies will be mainly sunny with highs in the 70s.

Dry wx will continue with high pressure for Monday night and
Tuesday as well. Lows will be seasonably cool, in the lower 50s,
with highs in the 70s.

Temps will warm up Wednesday as heights rise ahead of an
approaching shortwave. Highs in the 70s to lower 80s will result
in some destabilization, and the approaching system could bring a
few showers or thunderstorms.

Showers and thunderstorms will become more numerous Wednesday
night through Thursday, but we will continue to advertise
"scattered" coverage as the bulk of the energy with the shortwave
trough will lift off to our north. The atmosphere will
destabilize, so a few strong to marginally severe storms will be
possible Wednesday evening and Thursday.

The trend going into the weekend will be for warmer temperatures
and only isolated thunderstorms if any. High temperatures will
push well into the 80s late week, with some spots likely to touch
90 for the first time this year. Increasingly muggy air will
result in lows in the 60s to around 70.

18Z TAF DISCUSSION.

VFR. Some cumulus and cirrus will affect airports this TAF period
along with northwest winds up to 11 knots. An isolated SHRA/TSRA
cannot be ruled out near airports late this afternoon into the
evening but confidence is too low to include in TAFs attm.
