Hail and Damaging Winds in Tennessee, June 26, 2018

Area Forecast Discussion
National Weather Service Morristown TN
335 PM EDT Tue Jun 26 2018

.SHORT TERM...(Tonight and Wednesday)...Convective complex moving
into our northwest areas will spread south and east this
afternoon/early evening. Damaging wind gusts still look like the
primary threat over much of the area, but across northern areas,
especially areas that are already quite wet in southwest Virginia,
there will be an enhanced risk for flooding. Will leave FFA as is
for now. Expect convection to decrease behind this complex this
evening, then another mid/upper level short wave trough will be
approaching later tonight into Wednesday. Expect numerous showers
and thunderstorms again on Wednesday. Once again some of these
storms may be strong to severe, with damaging winds the primary
threat along with the possibility of flooding especially in areas
that are already wet. Will keep mention in the HWO for this.

.LONG TERM...(Wednesday night through Tuesday)...At the beginning
of this period, the upper trough and associated short waves will
be pushing through the area, with the first short wave possibly
about through the area Wednesday evening, but another short wave
looking to pass through during Wednesday night. On Thursday a weak
upper ridge builds in that will keep the chances of showers and
storms lower through the weekend. This setup is very sluggish to
move and we will probably have a consistent gradient of precip
chances through the weekend with only a few chances in our NE
areas into SW VA, but with scattered showers and storms each day
in the CHA area during that period. Early next week, the deeper
moisture axis will be pushed over us again, (although it will not
be all that rich), so better precip chances should return to SW VA
again then.

With the weak ridge building in this week, there should be a
corresponding weak heating later in the week with max temps in the
valley in the lower 90s by Friday for most of the valley
locations.
