600 PM CDT Sun Jun 24 2018

.UPDATE...
FOR 00Z AVIATION DISCUSSION.

.DISCUSSION...

Short term models are starting to line up a bit better for the
convective potential this evening and overnight. Existing
convection off to the west is associated with the strong upper
shortwave trough, and has additional development to the east along
a warm front. A few isolated to scattered thunderstorms will be
possible in the warm sector over the mid state this afternoon, but
chances will increase later this afternoon and evening as the
upper shortwave moves eastward across KY. CAMs want to develop a
MCV and bring it eastward and slightly southward, and looks to
impact northern zones during the evening and overnight hours. The
question will be how far south the extent of convection will
develop, but it at least looks like areas around and north of I-40
will see stronger convection per CAM consensus.

Any stronger thunderstorms that develop will have the potential
for damaging winds and even some hail late in the afternoon and
into the early overnight hours. Low level shear profiles are
somewhat decent, so cant rule out an isolated tornado as well.
After sunset, MUCAPE values do fall a bit, however around midnight
shear values will increase slightly as the upper trough axis will
be passing through the region and upper trough just off to our
north. At this time, the 850mb LLJ will increase to around 30
knots, which doesn't seem like much, however should be enough to
help sustain convection with the upper low and provide additional
moisture to the system. PWAT values are very high, showing around
2 inches this evening through the morning Monday, and current
dewpoints are in the low to mid 70s looking at obs. The MCV will
be moving relatively quick, but with deep moisture, high freezing
levels, and evenly distributed CAPE per model soundings, heavy
rain will be a threat overnight especially in the northwest zones.
Any training or slower moving convection will increase the threat
of flooding tonight through the early morning Monday.

Monday morning will see the upper low and MCV move off to the
east, but should still be impacting the northern Plateau Monday
morning. There may be some trailing showers and storms, but models
mostly have drier conditions moving in from west to east Monday.
Ridging looks to build in late Monday through early Wednesday, so
expecting mainly a diurnal shower and thunderstorm threat Tuesday
afternoon/early evening.

Wednesday looks to have another upper trough move east across the
Midwest, and drag a cold front through the mid state. Timing is a
little off between models, so kept chance pops in for now during
the day Wednesday. By Thursday, the trough moves off quickly and
upper ridging/high pressure moves in just as fast. Diurnal
convection cant be ruled out, but temperatures will be on the rise
as the impacts of upper ridging are felt. Current forecast has
highs in the low to mid 90s Thursday through Sunday, with isolated
afternoon showers and thunderstorms possible each day.

.AVIATION...
00Z TAF DISCUSSION.

BNA/MQY/CKV/CSV...Earlier convection has almost entirely
dissipated, but expect additional development later this evening
and overnight, and even lasting into the day Monday as another
shortwave moves across Middle Tennessee. The atmosphere remains
quite unstable, if a little dry, and the shortwave will help focus
available moisture.

.OHX WATCHES/WARNINGS/ADVISORIES...
NONE.
