Area Forecast Discussion
National Weather Service Tallahassee FL
819 PM EDT Mon Aug 23 2021
.UPDATE...
Small changes to the PoP forecast for tonight were made to account
for continued storm activity that is occurring across Georgia this
evening.
&&
.PREV DISCUSSION [729 PM EDT]...
.NEAR TERM [Through Tuesday]...
Showers and thunderstorms have formed mainly over the FL panhandle
so far this afternoon; however, isolated to scattered showers and
thunderstorms have also formed over SE AL and SW GA. Expect the
greatest threat from storms to be heavy rain and gusty winds at
times. Convection should remain fueled through sunset or so, with
conditions then drying out for most areas during the evening and
overnight. Tomorrow we'll continue our transition from troughing to
ridging. Southeast flow and moisture will become more prevalent
bringing typical summer like weather to region. Expect more showers
and thunderstorms tomorrow afternoon and highs in the upper 80s to
low 90s.
.SHORT AND LONG TERM [Tuesday Night Through Monday]...
As a continental subtropical high over CONUS and the Bermuda high
attempt to merge just north of our region, stretching from the Mid-
Atlantic and into the Great Plains, we'll have an inverted trough
making its way across Florida beginning Wednesday as it makes its
way westward. As it does so, we'll experience N-NEerly flow on
Wednesday and Thursday leading to relatively cooler temps. This
inverted trough is expected to be out of our CWA by Friday evening,
however, before exiting it is expected to increase our storm
coverage Friday afternoon as we get placed under the eastern side of
the trough. Once the trough is out of the region we'll transition
back to S-SEerly flow as the Bermuda high shifts westward over
our region. Otherwise, we'll experience the usual summertime
pattern, hot, humid, and afternoon convection, but with subsidence
in place, widespread coverage isn't expected. Expect overnight
temps in the low to mid 70s with daytime highs in the upper 80s on
Wednesday ahead of the inverted trough followed by a slight
warming into the low 90s this weekend.
.AVIATION...
[Through 00Z Wednesday]
TSRA invof the terminals should end around 02z. Cigs/vsbys will
lower to IFR by 09-10z at DHN and VLD. Brief restrictions also
possible at ABY and TLH; confidence is low so no mention attm.
Any IFR transitions to VFR by 13z, with renewed TSRA beginning
around 18z, mainly at ECP, TLH, and VLD. Light southwest winds.
.MARINE...
An Atlantic ridge axis will sharpen across the Florida Peninsula
tonight, then shift northward across the Southeast States by midweek
and linger there. This will bring a turn to moderate and
occasionally fresh east to southeast breezes.
.FIRE WEATHER...
Moist conditions will remain the dominant feature as showers and
thunderstorms remain possible each day. Dispersions below 20 for all
areas except the SE Big Bend area continue for today. Better
dispersion values are expected Tue above 30. Wednesday, we could see
some poor dispersion again, mainly for areas areas south of I-10 and
east of Tallahassee.
.HYDROLOGY...
Area rivers currently in flood should continue to fall over the next
several days. Showers and thunderstorms are forecast each day this
week, and although a few pockets of heavy rainfall will be possible,
additional river flooding is not anticipated.
.SPOTTER INFORMATION STATEMENT...
Spotter activation is not requested. However, spotters are always
encouraged to safely report significant weather conditions when they
occur (while following all local, state, and CDC guidelines) by
calling the office or tweeting us @NWSTallahassee.
