AREA FORECAST DISCUSSION
National Weather Service Jackson KY
456 PM EDT Sat May 23 2020

.SHORT TERM...(This evening through Sunday night)
Issued at 435 PM EDT SAT MAY 23 2020

Late this afternoon an upper level ridge extended from the
southeastern Conus into the Appalachians to lower Great Lakes
region. Meanwhile an upper level trough is moving from the upper
midwest toward the western Great Lakes. Weak shortwave ridging is
in place from the Arklatex region north through portions of the
Plains. At the surface, a weak warm front is lifting north across
the region and currently resides near the northern and eastern
portions of East KY. Scattered convection is currently occurring
across the entire region. The strongest storm that occurred in
Knox County produced some half inch size hail.

The initial challenge is the convection occurring with daytime
heating as a weak disturbance moves through the Lower OH Valley.
Recent mesoanalysis indicates that MLCAPE has reached 500 to 1000
J/kg across much of the area with MLCAPE about 1500 J/kg from I
75 and west. Mid level lapse rates remain quite meager in the 5.5
to 6C/km while low level lapse rates are generally 6.5 to around
7 C/km. MUCAPE in the southwest portion of the area is near or
slightly over 2000 J/kg. Bulk and effective shear are generally
under 20KT and a limiting factor to storm organization so storms
through this evening will remain more pulse type in nature though
shear is slightly better in the north 20 to 25kt so storms there
could be more linear in nature. Small hail and some wind gusts
will be possible with any convections this evening along with
lighting being the main threats. The convection should wane around
or shortly after sunset with the loss of daytime heating given the
lower end shear. Convection may linger a bit longer past sunset
along the western and northern portions of the area. Clouds
should scatter tonight and valley fog will be a threat and some
fog will develop near where heavier rain occurs. Lows tonight
should be mild, in the low to mid 60s.

The shortwave trough will pass north and northwest of the area as
it moves into the Great Lakes and weakens while the upper level
ridge axis is expected from the Bahamas and Hispaniola area
northwest into the Central Appalachians. The upper level flow will
become more southerly late tonight and into Sunday with the ridge
axis remaining generally just east of the area through the end of
the period. At the surface, a surface low will reach The Great
Lakes tonight with the trail warm front becoming moving east of
the area by Sunday and becoming somewhat diffuse. Although
convection cannot be ruled out late tonight or even on Sunday
night, coverage of convection should again peak on Sunday. Weak
shear and warm temperature aloft will be limiting factors to
organization and intensity. Temperatures will moderate further
into the mid 80s for highs with dewpoints well into the 60s
resulting in rather humid conditions.

Valley fog is anticipated as clouds again scatter out on Sunday
night as convection wanes around or near sunset. Lows will again
be mild in the 60s.

.LONG TERM...(Monday through Saturday)
Issued at 300 PM EDT SAT MAY 23 2020

More of the same is expected in the extended period of the
forecast. Diurnally driven showers and storms are on tap each day
through the end of the upcoming work week, as warm, moist, and
unstable air off the Gulf of Mexico is advected into the Ohio and
Tennessee valley regions, on the western periphery of the
subtropical high. This ridge is currently parked over the
southeastern CONUS. Coverage of showers and storms should be
isolated to scattered, as due to the lack of a focused triggering
mechanism. The afternoon and early evening hours will see the best
chances for both precipitation and thunderstorms. Warm and muggy
conditions will also be present, with daily highs in the 80s and
nightly lows in the 60s on tap for eastern Kentucky.

&&

.AVIATION...(For the 12Z TAFS through 12Z Sunday morning)
ISSUED AT 714 AM EDT SAT MAY 23 2020

As the sun rises, fog is starting to lift and dissipate, and
showers are starting to ramp up across eastern KY. Generally
scattered coverage is ongoing between KJKL to KSJS and points SE.
Expect isolated to scattered showers and thunderstorms throughout
the day, under generally VFR to, at times, MVFR conditions. Any
shower or storm that impacts a TAF site could briefly lower the
VIS and CIGs from the prevailing conditions. Until things really
get going during the day, the exact impacts and timing at each TAF
site are still a bit uncertain. This convection will be diurnally
driven, and will begin to dissipate heading into the overnight
hours. As heights increase aloft overnight, and skies scatter out
at times, can't rule out some additional fog development. Winds
will be generally be light during the period, under 10 kts.
