Discussion
Currently
Key west radar is detecting a few showers entering our westernmost
marine zones, and finding a broken line of showers with an
occasional lightning strike to our northwest outside of our marine
area of responsibility. The line of showers is moving towards the
west near 10 knots, and will likely clip our gulf marine zones in
the next few hours, but most likely will not impact the islands.

Temperatures across the island are in the mid 80s, with a few
outliers in the upper 80s. A weak cumulus line is beginning to
form along the lower keys. The key west waterspout model indicated
a chance of waterspouts today, possibly later this afternoon if
at all.

Short term
The front approaching this evening and overnight will provide
enough moisture and low level confluence to support shower
activity through early Wednesday morning. By mid day Wednesday dry
air should begin to filter in to the midlevels as the trough base
swings through, cutting off shower development. Will continue to
hold on to low chance pops for this evening and overnight.

Dewpoints temperatures will drop a few degrees post front,
allowing morning temperatures to fall into the lower 70s, with the
exception of the upper keys which could see lower temps in the
upper 60s as flow off the mainland will be a bit cooler. Wednesday
through Friday displays a similar pattern to the past few days,
as another trough drops out of the upper midwest and sweeps into
the southeast. Another weak front should push through the area on
Friday afternoon to evening. Winds will be relatively light during
the period before the next FROPA as a col over the area will be
the dominant feature.

Long term
Beginning Sunday high pressure will slowly build along the eastern
seaboard as flow aloft becomes less progressive and a more
blocking pattern develops over conus. As the high builds in,
easterly flow will again prevail over the islands and coastal
waters.

Marine
Light to gentle southwesterly to westerly breezes will prevail
over the keys coastal waters through this evening. Later this
evening and overnight a front approaching from the northwest will
veer winds to the northwest and increase a few knots, as well as
bring a chance of showers over all waters. By late Wednesday
morning shower activity will diminish and winds will generally be
out of the northwest to north between 5 and 10 knots.

Aviation
Vfr conditions are expected at eyw mth today. Tonight, episodes of
MVFR may occur with passing showers, with the risk highest between
25 09z-25 12z. Expect light southwesterly flow to shift to the west
this afternoon, and to the northwest late tonight, with sustained
flow of 5-10 knots.

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.
