Near term Today and tonight... Strong surface high to the north
and inverted trough over the atlantic coastal waters will produce
breezy ene winds today. Atlantic moisture will spread inland this
morning resulting in mostly cloudy skies for today. Inverted
trough will move inland and weaken this afternoon bringing a
slight chance of showers to SE ga this afternoon and tonight.

Temperatures today will be a few degrees higher than yesterday
with highs ranging from the upper 50s lower 60s over SE ga to
mostly low mid 60s across NE fl. Low temperatures tonight will
also moderate with lows in the upper 40s lower 50s.

Short term Wednesday through Friday night ... High pressure
will be to the east Wednesday as a cold front approaches from the
west. A warm and moist south southeast flow will prevail in this
pattern, with a few coastal showers possible. Activity associated
with front should hold off till after dark.

There are timing differences in the models in regards to the cold
frontal passage. Confidence is most favorable for a passage in the
overnight through early Thursday morning timeframe. With a nocturnal
passage instability will be limited, but a band of moderate to heavy
showers are anticipated just ahead, along and behind the front. A
narrow band of embedded thunderstorms will be possible along the
front, with a few possibly strong.

The region will be between the departing front and high pressure
building to the west Thursday afternoon. As a result, a breezy day
is anticipated with temperatures not gaining much off morning lows.

The high will continue to build from the west Thursday night through
Friday, then overhead Friday night. The high will provide mainly
clear skies, but a cool northwest to north flow will keep
temperatures below seasonal averages.

Long term Saturday through Monday ...

high pressure will be overhead Saturday into Saturday night,
yielding mainly clear skies and slowly moderating temperatures.

Long range models inconsistent for the Sunday into Monday
timeframe. At this point, favoring the potential for low pressure to
pass near this period, which could provide precipitation for Sunday
into Monday. However, with the model uncertainty will continue to
trend precipitation chances on the lower side, as low may be far
enough to the south for the dry air to remain place.

Below normal temperatures are expected through this period.

Aviation Stratocumulus clouds over the atlantic will spread
inland this morning with MVFR ceilings to prevail today. Ene winds
will increase today with gusts 20 to 25 knots near the east
coast.

Marine Inverted coastal trough will cause moderate east-
northeast winds today with caution levels. Trough will break down
by this evening as high pressure to the north shifts off the east
coast. Winds will increase from the southeast along with seas
tonight and will go with an advisory for offshore zones. A brief
lull in winds and seas may occur early Wednesday as winds become
southerly ahead of the next cold front. Advisory conditions return
Wednesday evening for all the waters as a strong cold front
approaches from the west with frontal passage across the waters
early Thursday morning. Advisory conditions will likely continue
through Thursday night as high pressure builds into the area from
the nw. Winds and seas will decrease Friday and Saturday.

Rip currents: moderate risk today through Wednesday as moderate
onshore winds continue.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
