Severe Thunderstorm Warning 95, NWS Jackson, KY

AREA FORECAST DISCUSSION
National Weather Service Jackson KY
300 PM EDT Tue Jul 18 2023

.SHORT TERM...(This evening through Wednesday night)
Issued at 258 PM EDT TUE JUL 18 2023

Presently, several near severe thunderstorms are developing in
Louisville's area and are tracking to the east-southeast. Through
the afternoon, those storms will gradually track into Jackson CWA. A
watch has been issued for the far southwest portions of the area.
Presently, damaging winds and large hail are the primary threats
with any of these afternoon storms. CAM solutions hint at a brief
break in the thunderstorm activity once these initial cells track
off to the east before an MCS tracks eastward overnight.

Synoptically, a closed circulation is located over the central
provinces of Canada with a large ridge of high pressure over the
Desert Southwest. The mean flow is sandwiched between the two
centers and within the mean flow; a perturbation is driving a
surface low along a stalled boundary that draped across the Ohio
Valley back to the Central Plains. Along that boundary is where the
aforementioned MCSs will track this afternoon and overnight. The
remnants of the overnight MCS will exit the CWA in the early hours
of Wednesday. A brief break in the showers and storms is expected
for Wednesday but clearing and instability building could take place
and if CAMs continue to remain in agreement, another MCS is expected
for Thursday afternoon. Presently, the system does appear to be
progressive but efficient rainfall coupled with a potential mid-
level moisture surge could bring hydro issues to the Cumberland
Basin Wednesday into Thursday. Presently not expecting any water
highlights but one could be issued in later shifts. The stalled
boundary is expected to dissipate overnight Thursday but with the
approach of a cold front, the area will be in the warm sector with
continued threats for showers and storms overnight Thursday
through the end of the period. Otherwise, the period will be
highlighted by multiple rounds of showers and storms with heavy
rain and the potential for damaging winds and large hail with near
normal temperatures.

.LONG TERM...(Wednesday night through Monday)
Issued at 529 AM EDT TUE JUL 18 2023

The period will start with strong upper level ridging over the
southwest and south central CONUS, and broad troughing from the
north central CONUS to the East Coast. In between, we will reside
under west northwest flow aloft near a wavering surface frontal
boundary-- a favorable position for periodic thunderstorms. A
couple of waves traveling through the trough will help to amplify
it with time, with the ridging retrograding over the western
CONUS. The amplifying pattern will send a cold front through our
area approximately Friday-- a little bit slower than was earlier
forecast. High pressure building in behind the front would allow
for mostly dry and less humid weather for the last few days of
the long term period.

The main issues in the long term period will be timing of
convective precip and the eventual frontal passage. As is usual,
models struggle with MCS evolution, with cascading effects further
out in time. The best forecast seems to be one of moderated POPs
until models hopefully latch on better in the nearer term. If
trends for a later fropa were to continue, dry and cooler weather
could be delayed a bit longer in later forecasts.

The most recent model runs have shifted further south and west
with the greatest threat of heavy rainfall on Wednesday and
Wednesday night. In terms of severe wx threat, it can't be ruled
out Thursday and Thursday night, but it's too early to stress it
due to a lack of confidence in the forecast details at that time
range.

.AVIATION...(For the 18Z TAFS through 18Z Wednesday afternoon)
ISSUED AT 142 PM EDT TUE JUL 18 2023

VFR conditions exist across all TAF sites at the moment; however,
as convection develops and tracks eastward, terminals KSME and
KLOZ could begin to see TSRA with reduced VISBY. Presently,
there's a TEMPO at KSME for the thunderstorms that're tracking
toward the terminal through 21Z. The remaining TAF sites will have
VCTS through the remainder of the afternoon but mainly after 20Z
for expected thunderstorm development. A brief lull in activity is
expected before another round of showers and storms move through
the region around 00Z. Precipitation is expected to taper off
toward 06Z or 07Z but lingering MVFR CIGS will remain in place
through the remainder of the TAF period.
