Near term /tonight-Monday/
Rest of this afternoon... A few showers beginning to pop-up across
the suwannee river valley of inland north fl and will continue to
do so up through inland SE ga through the late afternoon hours. An
isolated thunderstorm or two not totally out of the question with
surface based CAPE up to 500 j/kg in the region. Otherwise atlc
coast sea breeze will continue to push inland with e/se winds in
the 10-15g20 mph range.

Tonight... Weakening shortwave aloft will push east of the region
overnight and expect any showers around sunset to fade quickly
over inland SE ga with mostly clear/partly cloudy skies due to
some high clouds at times overnight. Lows still expected in the
55-60 deg range inland and 60-65 range along the coast. SE flow to
become near calm towards morning and will be supportive of patchy
and shallow ground fog area-wide inland from the coast. Some fog
may become locally dense but too soon to determine where and have
kept just patchy fog wording for now.

Monday... Low level high pressure ridge axis along the SE u.S.

Coast will begin to push further southward with axis ending up
into NE fl by the afternoon. Mid level ridging in the morning will
give way to another weak shortwave axis pushing along the north
gomex and into the SE u.S. Late in the day. So similar conds all
the way around with highs in the lower 80s inland and 70s at the
coast with atlc coast sea breeze pushing inland during the
afternoon hours. This boundary and just enough moisture across
inland SE ga and inland north fl may be just enough once again
with weak shortwave and sfc heating to trigger widely scattered
showers and possibly a thunderstorm, but once again overall
rainfall chances remain weak.

Short term (Monday night-Tuesday night)
Any remaining seabreeze convection across the inland areas will fade
out Monday evening due to loss of heating. High pressure offshore
the carolinas will weaken some and settle in across the fl peninsula
by the end of the period while a cold front stalls across north ga.

A weak short wave trough traverses the area Tuesday morning... But
will be offshore during the afternoon and evening as another ridge
begins to build in. Models indicate near nil rain chances across
most of the area... Except for isolated afternoon storms across the
extreme northern (ga) zones in closer proximity to the front.

With heights rising in the afternoon... Afternoon temps will also
correspondingly increase with most locations reaching the mid/upper
80s. Coastal areas held to the upper 70s to near 80 due to a
seabreeze.

Long term (Wednesday-Sunday)
There will be deep layer ridging over the area on Wednesday while a
cold front washes out near the altamaha. Conditions look mostly warm
and dry except for a few isolated storms near the altamaha in close
proximity of the front. Rain chances increase area wide towards the
end of the week as a deep low across the southwest u.S. Moves
northeast across the lower great lakes by the end of the week. Short
wave energy from this system will drive a cold front towards the
area on Friday... With the front washing out south of the area over
the weekend. Appears most of the dynamics will lift north of the
area but there will be a chance of showers and storms with the
approach of the front on Friday.

Best rain chances appear to be in the western portion from the
suwannee valley to inland southeast ga. Conditions appear to be dry
and warm next weekend with high pressure building into the area
behind the front.

Aviation Vfr with sct/bkn CU field in the 3500-5000 ft range at
the TAF sites as the atlc coast sea breeze pushes inland with se
winds at 8-12 knots. CU and wind fades at sunset leaving just a few
high clouds overnight. Near calm winds near sunrise in the 09-13z
and just enough moisture inland will support some MVFR vsbys at all
taf sites except ssi/sgj. OtherwiseVFR conds continue through
Monday morning.

Marine E/se flow around 10 knots with seas 3-6 ft and scec
headlines will continue in the offshore waters then as high pressure
ridge slides south of the waters on tue/wed expect shift to s/sw
winds with seas subsiding and no headlines. Then next ridge builds
into the carolinas by Thu with another shift back to e/se flow
closer to 15 knots shifting to the S by Friday and possibly closing
in on 15-20 knots and scec headlines may be possible once again.

Rip currents: moderate risk continues into Monday with lingering
long period swells that keeps breakers in the 3-4 ft range at the
beaches.

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.
