Cooler with filtered Sun today...

Inland frost tonight...

Near term Today & tonight...

dry conditions and below normal temperatures expected over the
next 24-hrs as surface high pressure builds east-northeast from
the lower ms river valley today toward western nc va through
tonight. Passing high and mid clouds will continue to stream
overhead from the wsw on the southern periphery of the sub-tropical
jet, then cloud cover will settle farther south over fl tonight
with less coverage over SE ga as a mid upper ridge begins to build
over the tx la ms gulf coast. Some short-range high resolution
models tried to generate some light precip associated with mid
level trough this afternoon into this evening across the suwannee
river valley, but only expect a period mostly cloudy skies mainly
across NE fl as the low levels will be too dry and thus evaporate
any mid level light precip before it reaches the ground. Prevailing
wnw surface winds 5-10 mph expected inland, generally west of
highway 301 under the influence of subsidence west of the area,
with winds along the coast and east of highway 301 veering more
nne at times as surface troughs pivot offshore of the SE atlantic
coast.

High temperatures will range in the upper 50s to lower 60s under
partly cloudy skies with waves of passing mid and high clouds.

Tonight as cloud shield settles southward over fl, clearing skies
over ga and stronger low level subsidence favor cooler conditions
with lows falling into the mid upper 30s. A few normally cooler
locales could briefly reach freezing mainly NW of waycross. More
clouds over NE fl will bring more mild temps with lows in the
upper 30s inland to lower 40s toward the st. Johns river basin
and atlantic coast. Included frost for inland SE ga and NE fl
west of the st. Johns river basin.

Short term Thursday through Friday night... Surface high pressure
centered to the north of the area Thursday will move off the east
coast on Friday. Upper level ridging combined with onshore winds
will result in dry and cool conditions. Thursday night will be
another cool night with frost possible over interior SE ga and the
suwannee river valley. Temperatures in those areas should remain
above freezing with lows in the mid 30s. Temperatures will moderate
back to near average levels Friday and Friday night as low level
moisture gradually increases.

Long term Saturday through Tuesday... Upper level ridge will
move east of the area on Saturday as a digging trough moves into the
plains states. Warming trend will continue with high temperatures
reaching the low 70s inland Saturday afternoon. Deep moisture will
start to arrive Saturday night as a short wave aloft and surface low
approaches from the gulf of mexico. 00z models closer than previous
runs but continue the trend of the gfs GEFS being faster and further
south with surface low that tracks across central fl. This scenario
would keep a more stable low level flow across SE ga NE fl with low
pressure remaining to our south. ECMWF continues to show surface low
just to our north with a slower and more amplified upper trough.

However, the ECMWF also shows limited instability despite the low
position due to ample moisture showers spreading across the area
Saturday night... And Sunday keeping daytime temperatures somewhat
lower than could be realized if there was more insolation. Consensus
pops indicate widespread showers... With moderate rainfall amounts
expected on Sunday. Isolated thunder possible across our southern
tier counties where weak instability may develop. Cold front passes
through the area Sunday night with clearing from west to east on
Monday. A return to temperatures slightly below normal for Monday
and Tuesday.

Aviation
PrevailingVFR conditions through 06z Thu with only passing mid
and high clouds. Winds 5-10 kts will waiver between wnw to nnw.

Marine
Nne winds will increase over the waters this morning to near 15
kts, then winds will settle back into the 10-15 kt range this
afternoon with some slight backing back to the nnw ahead of a weak
trough that will push offshore of the carolinas this evening.

Once this trough presses offshore, a stronger nne wind surge will
push southward over the local waters tonight with exercise caution
conditions expected as winds increase to 15-20 kts. After
midnight potential for a brief period of marginal advisory
conditions over the outer waters due to winds sustained near 20
kts for a few hours. Winds continue in the 15-20 kt range thu
through Fri as high pressure build north of the region and a long
fetch of easterly flow develops with building waves height
expected to reach advisory levels over at least the outer waters.

Elevated winds and seas continue into the weekend as an area of
low pressure approaches from the west.

Rip currents: low risk today. Moderate risk Thu as breezy onshore
flow develops. Elevated risk expected through the end of the week
with potential for high risk for portions of NE fl.
