Area Forecast Discussion
National Weather Service Morristown TN
232 PM EDT THU SEP 29 2016

.SHORT TERM...-- Changed Discussion --(Tonight and Tomorrow)...Upper low forecast to wobble
a bit further southeast before beginning to drift slowly northwest
and north. Best chance for any showers tonight will be in the same
areas that had them today...mostly northern areas...and may even be
a few more rumbles of thunder far northeast. Will carry slight
chance to chance PoPs north and central. On Friday drier air is
forecast to be pulled into the area...so should be precip free with
quite a bit of sunshine. Temps will continue to be a bit below
normal for the most part...and will stay fairly close to the MAV
numbers.

.LONG TERM...(Friday night through Thursday)... Closed low moves
northeast away from the area Friday night. Temperatures will
gradually warm into the weekend as more mild air flows back into the
region behind the low. A disintegrating boundary may bring a brief
shower to northwestern portions of the forecast area Sunday night,
but otherwise conditions look dry throughout the extended period as
a ridge of high pressure moves back into the region. This will also
help temperatures rebound back into the 80s for the first half of
next week. Models show a tropical system moving north along the East
Coast for late in the forecast period, but solutions vary greatly
from model to model. At this point, it is too early to determine
what impact, if any, this system will have on the forecast for late
next week.-- End Changed Discussion --
