Area Forecast Discussion
National Weather Service Nashville TN
628 PM CDT FRI AUG 26 2016

.UPDATE...
FOR 00Z AVIATION DISCUSSION.

&&

.DISCUSSION...

The forecast wont change too much each day as an upper high
slowly moves eastward towards the Atlantic and gets replaced by
another upper high/ridging next week. Subtle shortwave
disturbances within the upper flow combined with diurnal support
will be enough for some shower and thunderstorm activity through
the duration of the forecast. Temperatures look to remain very
consistent through the end of next week with highs mainly in the
low to mid 90s and lows in the low to mid 70s.

For the short term through Sunday, chances for showers and
thunderstorms will mainly be during the afternoon hours, but there
will still be chances for lingering showers to persist into the
evening. With weak upper level shear thanks to the upper closed
high, thunderstorms will be mainly pulse type and not move too
quickly. So if heavier showers and thunderstorms develop, slow
movement may bring some flood risks to impacted areas. Also, with
some enhanced areas of MUCAPE over the mid state during the
afternoon hours, some gusty winds will be possible with the higher
topped convection. Otherwise, just expecting typical isolated late
summer afternoon convection through the weekend.

After Sunday, the upper closed high begins to merge with the
approaching ridge, and keeps high pressure aloft through next
week. Another closed upper high will develop Tuesday, but doesnt
look to progress eastward like the previous high. Instead, the
ridge over the Plains will keep us in more of a northwesterly flow
pattern by late Wednesday. Again with subtle shortwaves embedded
within the upper flow, mainly afternoon showers and thunderstorms
are expected each day next week. By Friday, the ridge axis looks
to slide across the MS River Valley and may give us a dry weekend
across the mid state. For now have Friday and Friday night mainly
dry with a slight chance for afternoon thunderstorms on the
Plateau.

.AVIATION...
18Z TAF DISCUSSION.

Convective temps running just a few degrees above current temps
at this hour. Should see some isol to sct development aft 21z or
so. Otw, higher pressure remains stacked to our east. Convective
activity that does develop will move very slowly northward. Light
fog possible late tonight as current tover values are slightly
negative.

&&

.AVIATION...
00Z TAF DISCUSSION.

A rather typical summertime pattern will continue in place over
the Mid-State during the next 24 hrs, with a period of BR
expected during the late night/early morning hours, and isolated
thunderstorms during the afternoon. Visibilities in the BR will be
mainly MVFR, although can't rule out a brief period of IFR at one
or more of our airports. Daytime conditions will be mainly VFR,
except for a brief period of MVFR and/or IFR conditions if a
thunderstorm should happen to pass over an airport.

.OHX WATCHES/WARNINGS/ADVISORIES...
