Area Forecast Discussion
National Weather Service Morristown TN
311 PM EDT WED JUL 27 2016

.SHORT TERM...(Tonight and Tomorrow)...

Isolated-to-scattered convection will continue during the
overnight hours as an upper level disturbance approaches our area
from out of the southwest out ahead of an incoming trough. Some of
these showers and storms will still pose the risk of localized
heavy rainfall due to the high PWS that are in place. Overnight
lows will be mild with near 70 north and low-to-mid 70s south.

Tomorrow will feature the best rain chances we've had in quite some
time as an upper level disturbance gets absorbed into an incoming
trough and swings across the area through the day. This upper level
disturbance originated in the Gulf of Mexico and brings with it near
record PWS for this time of year. Soundings PWS top out around the 2
inch mark for most areas. Very high PWS combined with long skinny
CAPE profiles, 15 to 16k foot freezing levels, and a southwesterly
mean flow will lead to the threat of heavy rainfall. Models in
fairly good agreement that the main precip axis will stay off to our
north. Having said that, our northern most areas from the Northern
Plateau and up through Southwest Virginia will be closest to the
main axis and will therefore have the best chances of seeing heavier
rains. All other locations could still see periods of localized
heavy rain throughout the day. We will continue to monitor trends to
see if there is any southward shift in the main QPF axis. Increased
clouds and precip will allow for temps in the mid to upper 80s by
tomorrow afternoon. Incoming trough will also make for a breezy day
across the valley with sustained winds from 10 to 15 kts with
occasional gusts up to 20kts.

.LONG TERM...(THURSDAY NIGHT THROUGH WEDNESDAY)...

Low to our southwest that has been riding around the ridge will
likely move just north of our area as we head into the end of the
work week. This will help to bring a breakdown in the ridge and
bring in increased moisture that is wrapped up with this system.
Precipitable water values will increase to around or above 2 inches
on Thursday leading to chances to see heavy rainfall with storms in
the area. Highest PW values and best lift associated with this
system looks to be closer to Eastern Kentucky into the Virginias,
but that doesn't rule out the possibility of some of our counties
receiving heavy rain Thursday into Friday. In addition to heavy
rainfall in some locations, enough CAPE/shear could combine with the
impulse moving through to provide an environment where strong to
severe storms might be possible. If strong storms do form, the
biggest threats would be locally heavy rainfall and strong winds.
One thing to watch, in regards to storm strength, will be cloud
coverage during the daytime, as increased cloud coverage would
likely inhibit daytime destabilization of the atmosphere.

After this system moves through we will be under a broad upper level
trough that will help keep temperatures near normal and allow for
several weaker impulses to move through the region and bring
continuous chances for showers and thunderstorms in the
afternoon/evenings. Ridge begins to move in from the west towards
the end of the forecast leading to increasing temperatures and
decreasing rain chances.
