Area Forecast Discussion
National Weather Service Jacksonville FL
1230 AM EDT Fri Mar 19 2021

.AVIATION...
[Thru 06z Saturday]

VFR conditions expected through this evening. May see some lower
CIGs spread southward across eastern TAF sites after 00z Sat, but
will keep CIGS at or above BKN030 for now. Westerly surface winds
will be a bit lighter Today, but may occasionally gust to 15-20kts.
Winds will become N or NNE by this evening.

&&

.PREV DISCUSSION [858 PM EDT]...

.UPDATE...

A few prefrontal showers and thunderstorms are still lingering
around our southernmost counties, but they will end by midnight
tonight. The cold front has passed our northwestern SE GA counties
and will continue to push across the rest of the area over the
next few hours. Overnight low temperatures will be cool in the
upper 40s in SE GA and the Suwannee Valley and lower 50s in the
rest of NE FL.

&&

.NEAR TERM [Tonight through Friday]...Prefrontal storms moving
across NE Fl have indicated rotation in an area of favorable
instability and helicity. Expect storms to show a gradual
weakening trend after 22z with storms pushing offshore early this
evening. A cold front will push across the area by midnight
bringing cooler and drier conditions for Friday. High temperatures
will be in the upper 60s and lower 70s with mostly sunny skies.

.SHORT TERM [Friday night through Sunday night]...
A trough will drop south across the area bringing a surge of
northeast winds and coastal showers for the weekend as strong high
pressure builds in from the north. Cloudy and cooler weather can
be expected with temperatures only reaching the upper 50s/lower
60s on Saturday and the 60s on Sunday. Lows will be in the 40s...
and in the 50s near the NE Fl coast.

.LONG TERM [Monday Through Thursday]...Northeast flow will begin
to subside on Monday as strong high pressure to the north and
inverted trough offshore move to the northeast. A weaker pressure
gradient will also bring an end to the coastal shower activity.
Dry weather will continue through Tuesday due to ridging and dry
air over the area. Rain chances will increase Wednesday and
Thursday as an upper trough approaches from the west with latest
models showing large timing differences. Below average
temperatures on Monday will warm to above average for Wednesday
and Thursday.

.MARINE...Showers and thunderstorms will move across the waters
this evening. A few storms may be strong to severe with the chance
of a waterspout as some storms have shown rotation due to strong
shear. A cold front will move southeast of the area after
midnight which will end the shower activity and shift winds to the
northwest. Advisory conditions will continue for all marine zones
through Friday morning. A secondary trough will move south across
area Friday into Friday night, as strong high pressure builds to
the north. Over the weekend strong high pressure will be to the
north with an inverted low pressure trough developing over the
coastal waters. This low pressure area will move to the east of
the region early next week. Advisory conditions will develop again
this weekend with Gale force gusts possible as the pressure
gradient tightens.

Rip Currents: Moderate rip current risk today...becoming low risk
on Friday. High rip current risk expected this weekend as
northeast winds and surf increase.
