Area Forecast Discussion
National Weather Service Jacksonville FL
744 AM EDT Sat Mar 20 2021

.UPDATE...

Just a quick update to increase winds a bit and thus have issued
wind advisory along the coastal areas through this evening.

&&

.AVIATION...
[Through 12Z Sunday]

Widespread MVFR cigs expected today-tonight with slight chances
for IFR cigs at times, but better chances of IFR expected tonight.
A few showers on radar east-southeast of SGJ and expect showers
to become more prevalent this afternoon and evening, so have VCSH
for today, mainly for the coastal TAFs. Winds will be gusty from
about 360 to 040 degrees about 12-20 kt with gusts of near 30 kt.
Lower wind speeds expected for GNV. Winds only slightly relax
later tonight.

&&

.PREV DISCUSSION [246 AM EDT]...

.NEAR TERM [Through Tonight]...

Nor'easter pattern sets up with strong high pressure over the
northeastern U.S. with weak low pressure off the coast of eastern
FL...yielding breezy conditions inland, windy along the coast although
below wind advisory criteria. Coastal trough sets up well offshore Today
and works westward toward the coast Tonight. Should see showers and
t-storms increase in coverage over the coastal waters Today...with
scattered showers moving inland over coastal counties of NE FL.
Tonight...showers become widespread over coastal waters, with
increasing activity moving inland over our eastern counties...with
scattered showers possibly spreading into much of se GA.

In this type of pattern, with setup of a coastal trough and strong
onshore-directed low-level jet, with potential weak elevated instability...
concern about development of a convergent band of low-topped convection
that can produce a small-scale excessive rainfall event along the coast.
However...none of the global or higher-resolution model guidance is
suggesting this. Regardless, will have to monitor how precip pattern sets
up Tonight.

Cloud cover and N to NE winds will result in well below normal high
temperature in the upr 50s across se GA...around 60 I-10 corridor, and
60-65 ne FL. Low temperatures Tonight will be in the mid-upper 40s across
most of se GA and interior ne FL...with 50-55 eastern counties of ne FL.

.SHORT TERM [Sunday Through Monday]...

Breezy north-northeasterly winds will continue on into Sunday,
enhanced by the inverted trough positioned just off of the coast
resulting in high surf and rip currents along the shoreline along
with possible coastal flooding and shoreline erosion. Chances for
rainfall are expected to drop off on Monday as the pressure
gradient weakens as the area of high pressure and the inverted
trough start to lift out of the area. A warming trend for
temperatures will start off during this period and extend into
next week, with temperatures reaching up into the upper 60s and
lower 70s by Monday.

.LONG TERM [Tuesday Through Friday]...

Initially dry conditions on Tuesday will become more active as the
week progresses with the prevailing flow shifting about to become
more out of the southwest with a trough ahead of a frontal
boundary approaching from out of the west. Temperatures will trend
above the seasonal average for this period, with high temps
reaching up into the mid to upper 80s by the end of the week.

.MARINE...

Strong high pressure well to the north, and weak low pressure east of Florida,
will generate nor'easter conditions over the coastal waters through the weekend.
Gale warning for much of the offshore waters will be expanded to include the
coastal waters of se GA. Also expecting high surf and rip currents along entire
coast through the weekend. Conditions will gradually improve early next week as
the pressure gradient across the waters relaxes.

Rip Current risk will be High this weekend along coast of se GA
and ne FL.
