909 pm edt Thu aug 22 2019

Near term [through tonight]
A few storms are continuing to moving north across southern
georgia this evening, but within the last half hour have been
showing signs of weakening. Near term guidance suggests these
storms should diminish after 03z. Thereafter, expect conditions to
be fairly quiet overnight. Skies should gradually clear, though
some models suggest an area of fog low cloudiness could develop
across southeastern alabama before sunrise.

Expect another warm and humid night with lows in the mid 70s.

Prev discussion [720 pm edt]
Short term [tonight through Saturday]
Zonal flow aloft and ridging at the surface will prevail through
the start of the weekend. Afternoon storms will driven by the
seabreeze and associated mesoscale boundaries. On Friday, we may
see a lower coverage of storms from the big bend eastward where
drier air aloft will be present. Pops should return to normal by
Saturday. Highs are expected to reach the lower to middle 90s with
heat indices in the low 100s.

Long term [Saturday night through Thursday]
Through the extended period, the northern stream longwave trough
will amplify over the eastern CONUS as shortwaves move through the
northeast and the plains ms valley. A resultant wedge of high
pressure will force a front down the eastern seaboard as another
front approaches the southeast from the west. Eventually the
frontal boundaries will merge and become stationary across the
gulf coast resulting in above normal rain chances through the
whole period. Highs and lows will be right around seasonal
normals.

Aviation
[through 00z Saturday]
vfr conditions are expected to prevail through the evening hours.

Sct tsra will dissipate across the region after 02z. Model
guidance indicates some potential for MVFR ifr conditions near the
dhn terminal overnight, so have introduced this into the TAF this
cycle. Patchy MVFR conditions are possible at tlh vld before
sunrise, but confidence is too low to include in the TAF at this
point.VFR conditions all sites after 13z. Convection on Friday
should be isolated, so no TS groups were added beyond 18z.

Marine
Light winds and low seas will prevail into next week, with an
uptick in rain chances starting late in the weekend.

Fire weather
A wet pattern will return this weekend and linger through next
week. Patchy fog is possible in the early morning hours.

Otherwise no fire weather concerns.

Hydrology
A typical scattering of summertime storms is expected through
Saturday. Thereafter, we'll transition to a wet period as a front
stalls across the southeast. Due to the ongoing drought across
much of the region, widespread flooding is not anticipated at this
time.

The steinhatchee, fenholloway, and econfina remain in flood from
heavy rain this past weekend. All impacted rivers have crested and
water-levels have begun to fall. Hopefully, the bulk of the rain
next week will fall east and west of this region otherwise a
return to flood may be possible.

Spotter information statement
Spotter activation is not requested. However, spotters are always
encouraged to safely report significant weather conditions when they
occur by calling the office or tweeting us @nwstallahassee.
