Near term through tonight
Tropical storm cindy will move inland between a break in the two
ridges today. 500mb ridge east of the florida peninsula will
slowly nudge westward through tonight, and very warm conditions
aloft will prevail with 500mb temps of -4 to -5c. This will keep
storms below severe limits, in the garden variety category. The
surface ridge will remain east of the region, with the ridge axis
near the florida georgia border today. The ridge axis will slide
slowly southward tonight.

Deep moisture will remain over the region for one more day, with
precipitable water values around 2 inches. Deep southerly flow
will prevail, which will allow sea breeze boundaries to move
inland from both coasts. A few showers and storms are forecast to
develop along the sea breeze boundaries as they move inland, with
scattered to numerous late afternoon and evening showers and
storms across the interior between highway 301 and i-75. Locally
heavy rainfall is possible. Showers and storms will diminish
around midnight.

Mid to high clouds will finally beginning thinning out this
afternoon, which will lead to hot temperatures this afternoon.

Afternoon highs will be in the lower 90s, except upper 80s along
the east coast. Heat indices are forecast to be the highest so far
this summer, from 100-106 degrees this afternoon. Make sure to
drink plenty of water! Overnight lows tonight will be warm in the
low to mid 70s.

Short term Friday and Saturday
Strong upper ridging over the area with drier air aloft will lead
to more sunshine and less thunderstorm activity. Hot and humid
conditions will therefore prevail with heat indices maxing out
around 100-105 degrees each afternoon. Thunderstorm chances will
be relatively low for most of the area. A few thunderstorms,
however, will develop, with the best chances across inland
southeast georgia as storms develop upstream under an approaching
upper trough and push into our area. A few storms will also be
possible across the interior zones of northeast florida on
Saturday as the two seabreezes collide. Upper ridge and warm temps
aloft will keep convection below severe limits but locally heavy
rainfall will certainly be possible where storms do occur.

Long term Sunday through Wednesday
The upper ridge begins to get suppressed southward on Sunday as
upper troughing moves in. Moisture and large scale lift will be on
the increase and we will see a return to a wet weather pattern
through Tuesday as a frontal boundary stalls across the region.

Locally heavy rainfall will once again become a concern. Daytime
highs will be tempered and will return to below normal levels
given the expected increase in clouds storms. A transition to
onshore flow is expected on Wednesday as surface high pressure
builds just north of the area. The upper trough will also begin to
lift out, so we should see convective chances begin to decrease on
Wednesday, particularly across southeast georgia.

Aviation
GenerallyVFR conditions will prevail through the period.

Isolated to widely scattered showers and storms are forecast to
develop along the east coast sea breeze as it moves inland, with
storms most likely impacting kgnv, kvqq, and kjax late this
afternoon into the evening. South to southeast winds around 10
knots will prevail during the day, with light winds overnight.

Marine
Surface ridge axis will be near the fl ga border today and then
shift south into central florida through the weekend. Southerly
flow expected around 15 knots or less through the weekend with no
headlines expected. A frontal boundary will push into the region
Monday and stall across or just south of the region through the
middle of the week.

Rip currents: moderate risk of rip currents for the beaches
through Friday.

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.
