Marginal risk of strong to severe storms across NE fl
early this morning...

Short term Today and tonight... Widespread rain and isolated
thunder will move across the area early this morning. Current
airmass shows strong vertical wind shear but only weak elevated
instability. Still a slim chance of a strong to severe storm to
occur over NE fl until mid-morning as prefrontal trough and cold
front push east across the area into the atlantic. An isolated
storm may be capable of damaging winds or even an isolated
tornado. Average rainfall amounts will be near one inch across se
ga and NE fl. High pressure will build in from the west in the
afternoon with decreasing clouds and gusty westerly winds.

Temperatures will be a little cooler today behind the front with
afternoon temperatures in the 60s to lower 70s. Tonight
temperatures will fall into the mid upper 30s.

Short term Friday through Sunday ... High pressure will build
from the west Friday, then overhead for Saturday into Sunday.

Models continue to show a trough developing over south florida
late in the weekend, with lows tracking northeast along it. The
models have been inconsistent in timing of the lows as well as
northern extent of the precipitation. At this point, will keep
much of the precipitation to the south this period. Cooler than
normal temperatures are expected through this period, with freezes
possible both Friday night and Saturday night.

Long term Sunday night through Wednesday ... Model disagreement
and inconsistency continues in the Sunday night to Monday
timeframe over handling of energy riding northeast along trough to
the south. At this point will again favor much of this activity
remaining to the south with high helping to suppress this area.

High pressure will move to the east Monday night into Tuesday, with a
cold front moving through late Tuesday into Tuesday night. High
pressure is expected to build from the west for Wednesday.

Aviation Widespread rain will affect the TAF sites in NE fl se
ga until around 12-14z this morning when cold front pushes
offshore. Strong southerly winds will produce low level wind
shear ahead of front as winds increase to near 50 knots around
2000 feet. Expect MVFR conditions with possibility of ifr
conditions ahead of frontal passage.VFR conditions after 14z with
decreasing cloudiness and westerly winds.

Marine Strong cold front will sweep across the waters early
this morning accompanied by showers and a few storms with gusty
winds. SCA near shore with gale warning offshore remain in effect
until at least late morning. Winds and seas will start to decrease
this afternoon with advisory conditions expected to continue offshore.

High pressure will build in behind the front and be reinforced
this weekend. No headlines expected over the weekend.

Rip currents: moderate risk today. Low risk on 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.
