Area Forecast Discussion
National Weather Service Morristown TN
231 PM EDT SAT AUG 27 2016

.SHORT TERM...(Tonight and Sunday)...Not a lot of change to the
pattern...as we remain on the west side of a persistent east coast
mid level ridge.  After any isolated convection this evening
dissipates...expect some convection again Sunday afternoon. Models
hint at more convective energy so coverage might be a bit higher on
Sunday...thus will continue the previous forecast of chance PoPs all
areas. It will continue to be hot as well.  Will tweak most MAV high
temps up slightly for Sunday.

.LONG TERM...(Sunday night through Saturday)...Little change to the
overall weather pattern for much of the extended period, so forecast
contains minimal changes. High pressure remains the dominant weather
feature for much of the long term forecast, bringing continued above
normal temperatures.  Strong daytime heating combined with a few
weak disturbances will bring the chance for isolated convection most
afternoons, with the best chance across the higher elevations. Model
consistency begins to digress late in the period with regards to a
frontal boundary approaching the region, but generally do not see a
significant change in the weather pattern. For now, will continue to
carry low pops for the second half of the upcoming week.
