Area Forecast Discussion
National Weather Service Morristown TN
237 AM EDT Mon Jul 24 2017

.SHORT TERM...(Today and tonight)...Some drying today behind the
weak prefrontal trough shifting to our south.  The weak front will
remain to our north.  Models indicate enough convective energy
despite the drying to warrant mainly slight chance Pops for isolated
convection today, with the best chance across southern areas where
will carry low chance PoPs.  May be a lingering isolated shower or
thunderstorm early tonight mainly south, then should be precip free
overnight. It will be hot today but a bit less so than recent days.
MAV temps generally look reasonable so will stay close.

.LONG TERM...(Tuesday through Sunday)...Probability of showers and
thunderstorms drops off for most of the forecast area Tuesday into
Wednesday as a weak frontal boundary slips southward to Southeast
Tennessee and Southwest North Carolina. There will continue to be a
chance for convection in these areas near the boundary at mid week.
The remainder of the long term period is similar to previous
forecasts however, timing of the end of the work week frontal
boundary may be pushed back just a tad. It still looks like there
will be a small increase in pops for Thursday, but the main period
of unsettled weather with the next upper trough and cold front will
be Friday into Saturday as the front drops slowly south through the
Southern Appalachian region. Kept the Superblend token pops for
Sunday mainly along the Tennessee and North Carolina border. High
temperatures remain in the upper 80s and lower 90s until Friday when
clouds and precipitation with the front help to cool things down a
bit. Highs could drop to the lower and middle 80s behind the front
over the weekend so a little heat relief is in store.
