Area Forecast Discussion
National Weather Service Louisville KY
308 PM EDT Wed Aug 2 2017

.Short Term (Now through Thursday Night)...
Issued at 305 PM EDT Wed Aug 2 2017

Overall weather pattern through Thursday night looks unsettled with
a warm and moist low-level air mass, and broad and weak upper
trofiness both remaining in place. A series of weak disturbances
swinging through the upper trof will support scattered thunderstorm
development this afternoon, but convection will be more isolated on
Thursday afternoon.

Ongoing storms are focused mainly along and just south of the Ohio
River in response to low-level moisture pooling. Expect a slow
progression to the south and east for the remainder of the
afternoon, with a weakening/dissipating trend through most of the
evening as instability is lost. Not much shear to support any
organization, but sub-severe hail and wind potential is already
being realized per Mesonet obs and spotter reports.

Storm chances will be in play again on Thursday with the upper trof
axis remaining just off to our west. A sharper shortwave diving into
the Upper Midwest may keep convection a bit more focused to our
north and west, so our POPs will actually run lower than today.
Solid chance POPs along/north of Interstate 64, tapering down to a
dry forecast south of the Cumberland Parkway. Pulse storm hazards
remain on the table.

Will again see precip tapering off with the loss of heating, but
chances will start to ramp up again before daybreak Friday as the
upper trof digs into the Great Lakes and drives a cold front into
the Ohio Valley.

.Long Term (Friday through Wednesday)...
Issued at 305 PM EDT Wed Aug 2 2017

Upper-level trough pushing through the Great Lakes will drive its
associated surface cold front through the Ohio Valley on Friday.
Moderate instability is expected, with at least marginal shear even
though the better dynamics will remain focused along and north of
the I-70 corridor. West of Interstate 65 the severe threat will be
limited as the front moves through before max heating, but the
better chances will be farther east. SPC Day 3 Outlook has a
Marginal risk east of I-65, but the Slight risk is not too far north
of the area, so stay tuned. Could see marginally severe wind and
hail with the stronger storms, but still expect the bigger story to
be locally heavy rainfall.

We'll dry out from NW-SE late Friday and Friday night as the upper
trof departs to our east and a Canadian sfc high builds in. Expect
dry and pleasantly mild conditions for most of the weekend, with
temps running several degrees below normal both day and night. Sat
morning will be the coolest, but not quite as cool as previously
advertised.

Next upper trof starts to dig into the Plains on Sunday, and could
eject another disturbance into the region by late Sunday or Sunday
night. Best moisture feed late Sunday night into Monday morning
supports high-chance/low-likely POPs for that time period, even
looking at it from 5 days out. Lower confidence for the remainder of
Monday as any boundary may become oriented parallel to the zonal
flow aloft, and therefore could get hung up over the Tennessee
Valley. Diurnal 20-30 POPs on Tue-Wed for south-central Kentucky
with a dry forecast to the north, and temps continuing to run
slightly below normal.

&&

.Aviation (18Z TAF Update)...
Issued at 115 PM EDT Wed Aug 2 2017

Isolated to scattered showers and thunderstorms are being observed
in the region at this hour, with the greatest concentration of
precipitation along a boundary near the Ohio River. Expect activity
to drift eastward through the day. The showers/storms could reduce
cigs/vis to IFR/MVFR temporarily at some TAF sites. Should see
showers/storms begin to taper down near sunset as heat source
diminishes, though isolated storms can't be ruled out during the
overnight hours.
