Area Forecast Discussion
National Weather Service Tallahassee FL
312 PM EDT Sun Jun 13 2021

.NEAR TERM [Through Monday]...

An upper level trough will slowly move through the region over the
next 24 to 36 hours as it drift southeast. Cooler upper level temps
in association with this feature and plenty of low-level moisture
will allow scattered showers and thunderstorms to develop through
the remainder of the afternoon. The greatest chances for showers and
storms remains across the FL Panhandle and Big Bend where the best
combination of instability, low-level moisture, and convergence
along the seabreeze overlaps today. Further north, slightly drier
mid-level air and less low-level convergence behind a weak frontal
boundary will mean more isolated coverage of storms across AL/GA
this afternoon. Coverage begins to lessen around/after sunset as
daytime heating diminishes and instability lessens.

A little more dry air wraps around the upper level low into the
forecast area for Monday afternoon with northerly flow expected to
prevail. This likely means a little bit less coverage of showers and
storms for the afternoon with the main area of focus again being the
FL Panhandle and Big Bend where low level convergence is maximized.
Expecting slightly warmer temperatures in the low to mid 90s for
Monday.

.SHORT TERM [Monday Night Through Wednesday]...

As an upper level trough that has been over the region for several
days finally pushes well south of the region into the Florida
Peninsula, an upper level trough is expected to eject equatorward
into the Mid-Atlantic on Tuesday. This could lead to a diffluent
pattern aloft across the Big Bend region of Florida on Tuesday and
Wednesday, which could lead to an enhancement of thunderstorm
activity across this region on both days. Generally Tuesday and
Wednesday will be warm, with highs surging into the low to mid 90s
across the region. Tuesday will fell the warmest with maximum
apparent temperatures reaching the highest levels of the summer
this far with values reaching the low 100s through the afternoon
hours. low temperatures overnight are expected to drop into the
low 70s both Monday and Tuesday night.

.LONG TERM [Thursday Through Sunday]...

As the aforementioned upper level trough swings through the Mid-
Atlantic, and off the east coast, surface high pressure, and upper
level ridging is expected to build over the region on on Thursday
and Friday. PW values may remain high enough along the immediate
coastline that a few isolated showers and thunderstorms could
develop along the seabreeze; however, widespread activity is not
expected for both Thursday and Friday. The introduction late week
and closer towards the weekend of an early season tropical
disturbance will play a major role in the overall weather expected
across the region starting Saturday. Most model ensemble guidance
has a tropical disturbance moving into the Texas/Louisiana region
by Friday/Saturday. As is normal with any tropical disturbance, PW
values will be extremely high, with early model output currently
forecasting values between 2-2.25 inches along the east side of
this system. At this time, it is too early to tell what impacts,
if any, we could see from this system; however, with deep tropical
moisture being advected northward into our region by the weekend,
a wet weekend and early work week next week could be on tap. At
this time, continue to monitor future forecast updates.

&&

.AVIATION...
[Through 18Z Monday]

Outside of brief IFR conditions in any thunderstorms, VFR conditions
and light northwesterly winds will prevail through the day. The best
chance for storms will be across Florida terminals and into southern
Georgia. Some thunderstorms could contain gusty winds up to 30 or 40
knots for a brief moment. Patchy fog is possible early Monday
morning but confidence was too low to warrant mention in the TAFs.
&&

.MARINE...

Elevated winds and seas will be possible at times through the next
several days along with chances for showers and thunderstorms.
Storms will be especially elevated with thunderstorms over the
water, as localized increased winds and seas could lead to
dangerous boating conditions. Winds and seas could begin to pick
up late in the week and into the weekend, as a tropical disturbance
in the southwest Gulf of Mexico could lead to enhanced seas and
winds across the region later in the week.

&&

.FIRE WEATHER...

There are no significant fire weather concerns the next few days,
but afternoon rain chances will become more isolated through the
week along with warming temperatures.

&&

.HYDROLOGY...

Scattered showers and thunderstorms have already developed across
the region this afternoon, and are forecasted for the coming week
with Thursday and Friday remaining the driest of the days ahead.
while heavy downbursts could lead to localized flooding in poor
drainage areas, no impactful flooding is anticipated through the
end of the work week. The main focus will remain on the
possibility for rain chances to ramp up by the weekend and early
next work week as a tropical disturbance lists north into the Gulf
of Mexico by the end of the week. At this time, it is still too
soon to tell what, if any, impacts we could get from this system;
however, with elevated PW values expected, an expected wet pattern
could be in store for the region beyond the long term forecast.
