Flash Flood Warning 9, NWS Tallahassee, FL

Area Forecast Discussion
National Weather Service Tallahassee FL
344 AM EDT Sat Mar 19 2022

.NEAR TERM [Through Tonight]...

Ahead of the front, showers and isolated thunderstorms continue to
stream across mainly the Florida Panhandle and Big Bend this morning
and into portions of southern Georgia. There are some differences in
the CAM guidance today on how the handle the evolution of the
precipitation today - some diminish the activity later this morning
and bring a slug of moisture back to the Big Bend region later
tonight while others progress the current area east and develop
another line later today so confidence is on the lower side with
PoPs today. Either way, the better instability is across the western
two-thirds of the CWA this morning but will quickly shift east with
the better values (~1000 J/kg) across the Florida Big Bend and south
central Georgia later this morning. While shear isn't overly
impressive, for any storms that do develop across the Big Bend or
southeast Georgia this afternoon, there is enough that some of these
storms could be strong to severe. SPC has highlighted these areas in
a slight risk for today, with a marginal risk west of there that
covers portions of the Florida Panhandle and southwest Georgia. The
main threats will be damaging winds, hail and localized heavy rain,
although a tornado cannot be ruled out.

As the upper level trough swings across the region tonight,
precipitation chances will finally diminish with only low end chance
PoPs across the Big Bend tonight. Expect highs in the 70s to around
80 today with lows in the mid 40s to mid 50s.

.SHORT TERM [Sunday Through Monday]...

Finally, we get a reprieve from our active weather pattern.
Upper-level ridging builds in, and surface high pressure will
build in to the eastern US, sliding into the western Atlantic on
Monday. Thus, skies return to mostly sunny on Sunday, followed by
a few clouds Monday, but no rain is expected. Highs will be in
the lower to middle 70s on Sunday, then middle 70s to near 80 on
Monday. Lows Sunday night will mainly be in the 40s.

.LONG TERM [Monday Night Through Saturday]...

Well, our reprieve in the weather is unfortunately short-lived.
A deep longwave trough digs into the southern Plains by Tuesday.
The main energy then moves up into the Great Lakes by Wednesday
night with an elongating, increasingly positive-tilted trough
extending back into the Southwest US. This will keep things
unsettled in the long term.

At the surface, a deepening area of low pressure will move from
the southern Plains on Tuesday to the Great Lakes Wednesday,
bringing a cold front into the Southeast US Tuesday night into
Wednesday. There are model differences in timing of this system,
and likewise in the intensity of thunderstorms. It does appear
that there may be some severe weather risk with this next system
sometime Tuesday night into Wednesday. However, it remains too
early to delve deep into details. Stay tuned to later forecasts.

The front may stall near or south of our area late week as the
strongly positive-tilted trough trudges eastward. Another piece of
energy comes along and may try to bring the front northward again
Friday before clearing us out next weekend. However, being a week
out, it's rather uncertain how the pattern will evolve next week.

.AVIATION...
[Through 06Z Sunday]

An area of showers and thunderstorms continues to stretch from TLH
to VLD and will continue over the next few hours. Additional showers
and isolated thunderstorms will be possible today and the main focus
again will be in the same area of TLH to VLD. Expect IFR conditions
mainly this morning at the TAF sites but could see some improvement
to MVFR more quickly this morning across the ECP to DHN area.

&&

.MARINE...

Dense sea fog over the eastern waters will slowly dissipate
through this morning and early afternoon. Otherwise, scattered
showers and storms will be possible today as a cold front moves
through. North to northwest winds around 15 to 20 knots will
become easterly on Sunday. Winds and seas will increase next week
as the pressure gradient tightens between departing high pressure
to our east and deepening low pressure to the northwest. Advisory
level conditions are likely with some gusts to gale force
possible Tuesday into Wednesday.

&&

.FIRE WEATHER...

Showers and thunderstorms remain stretched across the Florida
Panhandle, Big Bend and south central Georgia this morning and
activity will continue to be possible through the day. High pressure
will build into the region tomorrow behind a cold front. Dry
conditions will prevail Sunday with RH values in the 30 percent
range. In addition, transport winds will be gusty and dispersion
values will be high. Areas of fog are expected this morning, some of
which will be dense, however, fog is not expected tomorrow.

&&

.HYDROLOGY...

A widespread 2 to 5 inches of rain fell across southeast Alabama
and the Florida Panhandle with some areas receiving as much as 8
inches during the last 24 hours. Elsewhere, rainfall totals were
mainly around 1 to 3 inches.

Looking at flash flooding potential, most of the rain today will
fall east of where the heaviest rainfall fell yesterday. Rainfall
totals will generally be less than half an inch, though an
isolated area could see 1 to 2 inches today. This should not
result in flash flooding in our area today. Jumping ahead to next
week's system, it appears a widespread 1 to 2 inches of rain is
possible, but some ensemble guidance suggests that higher totals
of 2 to 4 inches may be possible.

Along our rivers, today's rainfall brought many Panhandle and
southeast Alabama rivers into action stage. However, no rivers are
currently forecast to reach flood stage.
