405 am est Wed feb 20 2019

Near term today-tonight ...

coastal trough hanging on off the southeast u.S. Coast while a warm
front is lifting northward over north central fl. Low clouds,
light drizzle and a few showers affecting the region with the
showers mainly focused along and east of the trough over the area
waters. As both features lift north today, winds will come around to
the southeast and south bringing warmer temps to the region. Low
clouds will probably be slow to erode given the depth of the low
level moisture the fairly light sfc winds. Patchy dense fog also
anticipated over area waters and over the southeast zones as stratus
builds down and well above normal dewpoints (mid 60s) move over
cooler grounds, nearshore waters. MAX temps expected to be into the
70s over southeast ga but likely in the lower to mid 80s over
northeast fl, little cooler at the coast. A subtle increase in
deeper moisture, combined with low level convergence will lead to
convective showers during the latter half of today. Best chances
oriented from about the jax metro area southwest into clay, putnam,
and marion counties. Notable subsidence inversion in the mid levels
will definitely hinder updrafts but not out of the question to see a
couple of lightning strikes as enough SBCAPE of 1500-2000 j kg, LI -
3 to -5, and convergence is expected. Convective activity will
slowly shift northeast given broad south-southwest flow from sfc to
mid levels.

Tonight, isolated to scattered showers expected in the evening which
should fade by late evening and overnight. Lows only in the 60s due
to southerly flow. Light winds and abundant low level moisture will
lead to stratus and fog overnight, including over parts of the
nearshore waters.

Coastal flood advisory remains in effect with the high astronomical
tide from the full moon and the elevated winds and seas resulting in
coastal water levels about 1.4 feet above predicted astro tide and
about 1 foot above mean high higher water.

Short term (Thursday-Friday night)
Warm front will be well north of the region with all areas in the
warm sector. Slightly drier and more stable air moves in on Thursday
resulting in far less coverage of showers. Moisture levels increase
some Friday as a cold front stalls across cntl ga and there is
better moisture convergence pooling ahead of it resulting in
scattered afternoon showers. Best rain chances will be from the
upper suwannee valley to inland SE ga with generally low chances
elsewhere. There will also be a potential for patchy late night
fog low clouds due to elevated low level moisture in combination
with dry air aloft. Temps will be much above normal for this time of
year with highs in the 80s inland and 70s along the coast. Lows in
the 60s.

Long term (Saturday-Tuesday)
The region will remain between high pressure to the east southeast
and elongated frontal boundary to the north northwest through
Saturday night. A cold front will move southeast into the area
Sunday and stall south of the region on Monday. The chance for
showers will increase Sunday into Sunday night as the front moves
through. Both gfs ECMWF are indicating a disturbance will move in
from the gulf coast on Tuesday and may produce widespread rain to
the area. Temps will be well above normal through the weekend and
cool some early next week but still remain above normal.

Aviation
Ifr to lifr conditions will continue to prevail at the regional
terminals through the late morning and early afternoon hours.

Cigs should lift gradually during the day with MVFR toVFR cigs.

Though most of the moderate shower activity will lift of kssi this
morning, scattered showers are expected across northeast fl
this afternoon and evening. Winds will shift around from northeast
east to southeast and south during the day with speeds AOB 10 kt,
but higher winds initially for kssi.

Marine
A trough of low pressure near the southeast georgia coast resulting
in lingering affects of northeaster conditions but will abate
as the trough lifts north today. A warm front across northeast fl
today will also lift to the north of the area through tonight.

Moderate winds and elevated seas will maintain the SCA for area
waters at this time, but winds will relax and allow the sca
nearshore to be ending later this morning. Latest reports showed 6-7
ft at nearshore buoys at 09z. Continued SCA offshore until thu
morning. Otherwise, winds will be veering to the south and southeast
through the next couple of days and up to 15 knots or so at times.

Another backdoor cold front will move into the coastal georgia
waters late Friday, lifting back north by Saturday. A stronger
cold front will move into the region on Sunday.

Rip currents: a moderate to high risk of rip currents will
continue at area beaches today given elevated seas. With seas dropping
further on Thursday most beaches go to moderate risk.
