Area forecast discussion, Jul 23, 2:59 PM EDT, 3 hours 41 minutes before

Area Forecast Discussion
National Weather Service Morristown TN
259 PM EDT SAT JUL 23 2016

.SHORT TERM...(Tonight and Sunday)...The rather stagnant pattern
will continue over the area as we remain under the broad upper
ridge.  Expect some isolated to scattered convection...especially
during the afternoon and evening.  The heat will continue as well.
Will go close to MAV temps for lows...but will continue to go a bit
higher than MAV most locations for max temps.

.LONG TERM...(Sunday night through Saturday)...Overall, pattern
still looks similar to yesterday's forecast. Increase in rain
chances still expected as a front drops southward by early week
along with more seasonable temperatures.

As we begin the period on Sunday night high pressure still over the
area but not near as amplified as in previous days. A few lingering
diurnal showers and storms may still be around early with rain
chances decreasing late. Mild lows expected with temps upper 60s to
near 70 north and mid 70s south. High pressure tries to hang on
through Monday despite the fact that a front is dropping down out of
the Ohio River Valley. Models in decent agreement that high slows
front delaying it's arrival, compared to model runs the past few
days, until Tuesday. Even though the front is slightly delayed,
still expecting diurnal convection Monday afternoon. Still hot on
Monday with highs in the low to mid 90s and mild overnight lows
with similar values to Sunday night.

On Tuesday this weak and broad front finally drifts into the area
from out of the north and will stall out across our area thorugh at
least Thursday. During this time rain/storm chances will be in the
chance and likely category as the front will serve as a triggering
mechanism for convection. There could be some locally heavy
rainfall during this time as soundings indicate increasing pws with
arrival of the front combined with very weak flow aloft which should
produce slow storm motions. On Friday a very broad upper level
trough starts to dip down into the Southern Appalachians along with
another front. This will allow precip chances to remain in the
chance to likely categories. Trough remains across the area into
Saturday, which will keep high-end chance pops in the forecast.
Temperatures from Tuesday through Saturday should be more seasonable
due to increasing rain chances and cloud cover.
