Discussion
Water vapor imagery reveals a chaotic maelstrom across the
western north atlantic and the southeastern united states. Nldn
lightning data highlights the release of daytime heating
throughout the same region, with thunderstorms flourishing along
diurnal boundaries. The one exception is across the western north
atlantic where a tutt-like cell and its steepened mid-upper level
lapse rates have tapped into the lower level maritime cumulus.

Mean low-level ridging continues to stretch west across northern
florida, and yet it has weakened in the last 12 hours, with
falling heights (see regional 00z raobs) between 925-700 mb. The
200 mb raobs (mfl, key, and mynn) did not register the western
periphery of the previously analyzed tutt-like feature. This may
be due to contamination from convective anvils, because satellite
derived vorticity products from cimms seem to think its there.

Nevertheless, this feature may come into play Friday through
Sunday as it lumbers westward.

Forecast
We tweaked the wind forecast to account for a subtle nocturnal
east-southeasterly surge which is now impinging along the reef
tract, with winds on the low end of 10 to 15 knots. We have held
at slight rain chances overnight due to inhibition and dry air
sampled at 880 mb by the kkey raob. The forecast is on track and
needs no further adjustments.

Marine
High pressure will extend from the atlantic westward across the
florida peninsula tonight through Sunday. This will result in
gentle to moderate, east to southeast breezes. Breezes will
diminish Monday through Tuesday night as high pressure settles
southward towards the florida keys. We have winds trending to 5 to
10 knots Tuesday and Tuesday night across the straits of florida,
where in fact the eastern straits southeast of the upper keys will
be closer to near 10 knots, and the western straits closer to near
5 knots.

Aviation
Vfr conditions will prevail for the overnight period. Showers thus
far has stayed over the gulfside waters and are moving west.

Remnant boundaries from earlier convection off of southern mainland
florida reside over the extreme southeast gulf waters while
boundaries from andros island are moving westward in the flow.

Together these boundaries could initiate further convection and
could possible move over the terminals. Exact timing and placement
is too low at this time to include in the forecast.

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.
