447 am edt Sat mar 23 2019

Near term through tonight
Patchy dense fog has developed early this morning out across the
suwannee valley as light west winds have advected moisture in from
the gulf there. Mostly clear skies with patchy shallow fog
elsewhere. The fog will lift by mid morning.

High pressure will move from the upper mid west to the north
carolina coast tonight which pushes a dry backdoor front across
the area today. The front will wash out over the area tonight as
short wave ridging moves in. Winds shift to northeast behind the
front today resulting in cooler temps near the coast (upper 60s-
near 70) vs inland (mid-upper 70s). Winds will be somewhat lighter
than yesterday as the gradient will be more relaxed with the
large storm system well to the north lifting away. As the high
moves to the nc coast tonight... Return of moisture may bring in a
few coastal clouds to the lower NE fl coast (flagler... St johns)
but otherwise cool and dry tonight. Lows tonight ranging from the
40s inland to 50s coast.

Short term Sunday-Monday sfc high pressure system initially
along the north carolina coast Sunday morning will move east-
southeast resulting in warm southerly flow on Sunday with a
gradual increase in low level moisture. Dry conditions will
prevail with MAX temps from mid 70s (coast) to around 80 (inland).

A cold front will be moving into southeast state Sunday night
causing winds to continue to veer. Minimum temps in the 50s Sunday
night with some late night low stratus and some patchy fog
possible, mainly inland zones.

Monday, southwest to west low level flow expected as the front
approaches with breezy conditions, mainly over southeast ga. A low
chance of showers or a thunderstorm Monday aftn from about i-10
northward as deeper moisture encroaches on the forecast region.

Monday night, digging mid upper level trough over the southeast
states will result in frontal wave developing over the carolinas
with pockets of deep moisture and the cold front passing over the
forecast area. Overall, best chance of showers or a thunderstorm
will be over the NRN 2 3rds of the area where better forcing and
moisture will be located.

Long term (tue-fri)
Cold front moves southward through the area Tuesday with a chance
of showers possible from strong low level convergence due to
a northeast surge of winds. Wednesday, strong high pressure over
the mid atlantic around 1037 mb will allow for breezy conditions,
windy along coast, with coastal showers that could affect the fl
coastline at times. Prelim look at winds shows sustained near 20
mph and gusts of 30-35 mph Tue night through Wed night for coastal
locations. Brief return to slightly below normal temperatures
mid- week before warmer conditions return by Friday as low level
flow veers ahead of the next cold front approaching the southeast
states.

Aviation PrevailingVFR.

Marine High pressure moves to just north of the waters today
and then offshore beginning Sunday. Winds become northeast today
and veer into the south by Monday. No headlines through early next
week. A large storm system well north of the waters will produce
long period swells across the waters through Sunday which will
produce combined seas of 2 to 3 feet near shore and 3 to 5 feet
offshore. Winds seas increase ahead of a cold front that
approaches Monday night, and moves across the waters early
Tuesday. Strong high pressure builds north of the waters,
resulting in a substantial increase in winds seas as a nor'easter
pattern sets up, with SCA conditions expected Tuesday night
through at least Thursday.

Rip currents: a long period swell from the northeast in combination
of a developing onshore flow warrants a moderate risk of rip
currents at the NE fl beaches both today and Sunday. The risk is
expected to be low at the SE ga beaches.

Fire weather
Critically low rh values inland areas today at 20-25 percent
but sustained winds do not meet criteria for red flag warnings.

Dispersion values near average at about 40-55 today. Onshore flow
on Sunday will help ease the very dry conditions of the past
couple of days with min rh values falling to about 30-35 percent.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
