Area Forecast Discussion
National Weather Service Tallahassee FL
150 PM EDT Sun Aug 7 2022

.AVIATION...
[Through 18Z Monday]

Scattered showers and thunderstorms today will keep TSRA to VCTS
conditions at all terminals through the remainder of the evening.
Flight conditions would possibly drop to MVFR/IFR levels in the
vicinity of these showers and thunderstorms. Otherwise, VFR
conditions are expected to prevail. Overnight, MVFR visibilities
are expected to develop at ABY and DHN. All other terminals should
remain at VFR flight levels through the morning hours.

&&

.PREV DISCUSSION [945 AM EDT]...

.NEAR TERM [Through Tonight]...

Surface ridging stretches from the western Atlantic westward through
the southeast US. Mid level ridging overhead will weaken and move
westward as an inverted trough makes its way towards the Florida
east coast later today. This will keep high PWATs in place ranging
from 1.9 to 2.1 inches.

A typical summertime regime is in place with expectations for
seabreeze convection, as well as diurnally-driven convection, to
develop beginning by mid morning. The highest rain chances for
today, and highest rain amounts, will be in the western Florida
panhandle northward into southeast Alabama. Slow storm motions are
expected so localized heavy rainfall could occur with slower moving
storms along with gusty winds.

Outside of rainfall, high temperatures today will reach the low 90s.
Couple that with low to mid 70 dewpoints and heat indices will reach
the low 100s.

.SHORT AND LONG TERM [Monday Through Sunday]...

The forecast area will spend much of the upcoming week situated
between two upper level ridges while an upper level trough slowly
moves through the area from the east. This upper level trough,
along with abundant deep-layer moisture moving into the region on
southeasterly flow, will lead to fairly wet pattern across the
area Monday through Wednesday. Widespread showers and
thunderstorms are expected on these days. Storms will follow a
typical summertime pattern with plenty of storms over the marine
areas in the morning hours with coverage quickly increasing in the
late morning and afternoon hours overland and on the seabreeze's
inland progression.

By the later part of the upcoming week, the ridge across the
western Atlantic will begin to weaken while the ridge over the
central US amplifies. This will bring an increase in upper level
flow out of the north. Rain chances look to remain elevated for
the end of the week and the upcoming weekend. This type of pattern
can bring weakening frontal boundaries into the region which help
reinforce rain chances as these boundaries stall, though it can
also bring mid-level drier air to the region. For now, kept rain
chances above normal late in the period. With increased rain
chances temperatures will run around normal to slightly below
normal in the afternoons.

.MARINE...

East to southeasterly flow is expected for most of the upcoming
period, with winds becoming more southwesterly late in the week.
An increase in shower and thunderstorm chances is expected through
the week, especially in the overnight hours.

.FIRE WEATHER...

Expect late morning and afternoon chances for showers and
thunderstorms throughout the upcoming week. Outside of rain chances,
afternoon high temperatures will reach the lower to middle 90s. This
will lead to heat index values topping 100 degrees each day. Aside
from this and low dispersions, no major fire weather concerns are
anticipated.

.HYDROLOGY...

A wetter pattern is forecast to develop through the upcoming week.
Widespread forecast rainfall amounts from today through Saturday
range around 1 to 2 inches. However, with rain chances and deep-
layer moisture on the rise, localized higher amounts are possible
as is typical with summertime convection. The main concerns will
be localized flooding in areas of slow moving thunderstorms.
Widespread flash flooding and 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.
