Area forecast discussion, Aug 4, 4:08 PM EDT, 2 minutes before
Area Forecast Discussion
National Weather Service Tallahassee FL
408 PM EDT Thu Aug 4 2022

.NEAR TERM [Through Friday]...

Showers and thunderstorms have picked up this afternoon, primarily
across northern FL. Mesoanalyst shows the DCAPE gradient over SW GA
and the Big Bend of about 700 to 1100 J/kg, with slightly lower
amounts being observed east of the gradient. PWATs over the CWA are
estimated around 1.70 to 2.0 inches, while shear is very low. A few
strong storms could be possible, but should remain below criteria.
Heavy rain and gusty winds will be the primary threats for this
afternoon and into the early evening. Then tonight, skies clear,
with overnight lows falling into the low to mid 70s.

Tomorrow the forecast is on repeat, we'll see fair weather cumulus
develop in the morning. Showers and storms should start off along
the coast before spreading inland along the various sea breezes and
outflow boundaries. High temps will be in the low to mid 90s.

.SHORT TERM [Friday Night Through Saturday Night]...

Throughout the short term we'll have ridging sliding off to the west
as an approaching easterly wave moves in from the east. We'll have
enhanced rain chances offshore and along the Gulf Coast. Otherwise,
expect highs generally in the low to mid 90s with overnight lows
generally in the low to mid 70s.

.LONG TERM [Sunday Through Thursday]...

As the aforementioned easterly wave makes its way across our Gulf
waters Sunday through Tuesday we can expect enhanced rain chances
across the region as we'll be placed on the eastern side of the
wave, which is collocated with upper level support for rising
motion. After Tuesday rain chances decrease a little and we're
yet again placed on the southerly flow side of the next ridge,
thus inducing the routine summertime pattern. Expect daytime highs
to generally be in the low 90s with overnight lows in the mid
70s.

&&

.AVIATION...
[Through 18Z Friday]

Fair weather cumulus can be observed across much of the region, with
a few showers and thunderstorms developing along the seabreeze. VFR
conditions are expected to prevail outside of showers and
thunderstorms which may reduce ceilings and visibility briefly.
Precip chances decrease around sunset and with dry conditions
expected for the overnight.

&&

.MARINE...

Showers and thunderstorms are expected each day across the marine
area with chances increasing for the weekend into next week as an
upper level disturbances moves from the Atlantic into the Gulf of
Mexico. Winds will mainly be east to southeast with winds of 5-10kts
increasing to 10-15kts on Sunday. Similarly, seas of 1-2 feet will
increase to 2-3 feet late in the weekend into early next week.

&&

.FIRE WEATHER...

The main fire weather concern will areas of low dispersion today and
tomorrow. Daily showers and thunderstorms will be possible,
otherwise dry, although humid conditions, are expected.

&&

.HYDROLOGY...

No areal or river flooding is expected for the next 7 days. However,
thunderstorms will be capable of producing locally heavy downpours
which can lead to short-lived drainage issues.

&&

.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
