National Weather Service Morristown TN
303 PM EDT Wed May 29 2019

.SHORT TERM...(Tonight and Thursday)...
Deep southwesterly flow continues across the Ohio and Tennessee
Valleys. Several weak impulses just ahead of the main area of
convection in northern KY will move east southeast across extreme
northeast TN and SW VA late this afternoon and early evening or
around sunset. The main line in eastern KY was moving east toward
southern West Virginia with a few reports of hail and higher winds.
A few showers had already developed before 18Z and some storms
about to move over Wise County Virginia. These showers and storms
could be locally strong across SW VA with locally damaging
winds...small hail and heavy rainfall late this afternoon to early
evening. However overall the hot and humid conditions will
continue through the afternoon. Temperatures at mid afternoon were
in the lower 90s most lower elevations central and southern
valley but in the 80s across extreme northeast Tennessee and
southwest Virginia where there is more cloud cover.

The storms should die down early tonight with skies partly cloudy
with mostly high clouds overnight and warm overnight lows in the mid
60s to lower 70s. Thursday the cold front over the Mississippi and
lower Ohio Valleys will make its push east into middle Tennessee and
central Kentucky by late in the day. Scattered showers and storms
are expected to develop from NW to SE in the afternoon across middle
Tennessee and slowly spread east into the northern part of the
forecast area by late in the day. A few strong storms with damaging
wind and large hail are possible mainly northern plateau and
southwest Virginia. Thursday with the convection not moving in until
around mid afternoon temperatures will still be several degrees
above normal. Highs in the mid 80s to lower 90s.

.LONG TERM...(Thursday night through Wednesday)...
Models are in decent agreement overall, and show a cold front
swinging through during the Thursday night/early Friday time frame
and a mid/upper level short wave trough moving across Friday.
Moisture still looks somewhat limited, and convective energy looks
best north where there will be more cooling aloft. Will carry
chance PoPs for some showers and thunderstorms north and no more
than slight chance south. Slightly drier air will move in later
Friday night into Saturday, but then another cold front is
forecast to approach and push through later Saturday night and
Sunday with another chance for convection. Drier and cooler air
will move in again for Monday as the area will be dominated by
northwest flow aloft and an area of surface high pressure builds
in, but temperatures will just drop to near or slightly above
normal. Tuesday should be dry as well, then moisture is forecast
to increase enough by Wednesday to include some showers and
thunderstorms once again.
