Area Forecast Discussion
National Weather Service Tallahassee FL
136 PM EDT Tue Jul 20 2021

.AVIATION...
[Through 18Z Wednesday]

Widespread rain showers and thunderstorms are expected to continue
through the remainder of the afternoon and evening hours across
all terminals. This will lower conditions to near MVFR to IFR
levels briefly before VFR conditions improve outside of showers
and thunderstorms. VFR conditions are expected to resume after
sunset; however, lower CIGS near IFR to LIFR levels are expected
to develop at DHN, ABY, and VLD terminals by early morning. These
levels will give way to VFR levels by mid morning before another
day of showers and thunderstorms develops across the region.

.PREV DISCUSSION [1057 AM EDT]...

.NEAR TERM [Through Tonight]...

The southeast will remain on the southern side of an upper trough
axis with a closed low developing and retrograding southwest to
the Texas Piney Woods. Deep southwest to west flow will continue
with high moisture continuing to advect into the area. There were
a few pockets of heavier rainfall yesterday and localized rainfall
amounts over 3 inches but for the most part the convection was
fairly progressive. Expect the same setup for today with slightly
increased steering flow with scattered to numerous convection,
favoring the coastal sections early this morning transitioning
onshore through the morning hours with additional development
across our Alabama and Georgia counties through the day. Highs
today will mainly be in the 80s with lows tonight in the mid 70s.

.SHORT TERM [Wednesday Through Thursday]...

The very wet pattern in place will continue for at least one more
day on Wednesday before a slow transition in the pattern develops
towards the end of the week. In the upper levels, a large cutoff
low to the northwest of the forecast area will translate west
through the middle of the week as an upper level ridge builds in
from the east. Moist southwest flow across the forecast area will
lead to widely-scattered/numerous showers and thunderstorms
across the forecast area. Similar to recent days, very moist
conditions in place will lead to a low end risk of isolated flash
flooding due to the potential for high rain rates in any storms.

The upper level ridge builds across the forecast area on Thursday
and the supply of deep tropical moisture is expected to lessen as
the lower level flow becomes westerly. Despite the westerly flow
developing, there will still be plenty of leftover moisture on
the northern periphery of this upper level ridge to support
scattered showers and thunderstorms in the afternoon.

With rain chances decreasing on Thursday, expect warming
temperatures into the low 90s.

.LONG TERM [Thursday Night Through Tuesday]...

Daily chances for showers and thunderstorms will continue through
the end of the week, and possibly into early next week depending
on the evolution of the upper level pattern. At the upper levels,
the ridge will continue to control the pattern over the northern
Gulf while northwesterly flow slowly develops through the weekend
as the ridge axis translates west. Plenty of low-level moisture
will hang around across the area and allow scattered
thunderstorms each afternoon. Temperatures will remain near or
above average through the period with the middle 90s possible by
the end of the weekend as a stronger upper level ridge
potentially develops over the mid-south. Depending on the strength
and location of this ridge, we could see below average rain
chances return to the area by the start of next week.

.MARINE...

Southerly winds around 10 knots and low seas around 1 to 2 feet
are expected through the next few days before westerly flow and
northwesterly flow develop for the remainder of the next week.
Widespread showers and thunderstorms are expected today and
Wednesday, especially in the overnight and morning hours, before
storms become more scattered over the weekend.

.FIRE WEATHER...

Unsettled weather pattern continues for the next several days
with scattered to numerous showers and storms expected each day.
Given the increased rain potential and high humidity levels, there
are no fire weather concerns at this time.

.HYDROLOGY...

Widespread rainfall of 1 to 2 inches is expected the next few
days, especially across our north and west zones. Isolated amounts
in locations where training of storms, or storms move slowly,
could easily be double this range. The widespread amounts of 1 to
2 inches should not be enough to cause a large response on area
rivers, but some rises are possible, especially on the smaller
creeks and rivers which respond to rainfall much quicker.

.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.
