Discussion
Temperatures are mainly in the upper 70s this morning, with dew
points mostly in the upper 60s. Easterly breezes have kept steady
near 20 knots overnight in the marine areas, with gusts along the
island chain approaching that value. Goes-east infrared imagery
depicted mostly clear skies, with cumulus becoming scattered to
broken over portions of the straits. The key west WSR-88D has been
tracking scattered showers and a couple of isolated thunderstorms
in the straits beyond 40 nm, enhanced by cuban outflow meeting the
easterly surge.

Through Tuesday, weather conditions will remain very similar to
the past several days. A strong upper-level ridge will limit pwat
values to less than 1 inch, with scarce low-level moisture and
tremendous dry air aloft preventing shower formation across the
keys and coastal waters (with the exception of the far outer
straits). Easterly surges and lulls will continue, with the
fastest winds typically occurring at night. These surges will be
accompanied by partly cloudy skies, with mostly sunny conditions
expected during the daytime. Highs reach the upper 80s to near 90
at a few locations, with lows mostly falling into the upper 70s.

Tuesday night through Saturday, the aforementioned ridge aloft
will weaken a bit as a significant trough moving across the
central united states flattens the ridge. This confines higher
heights to the deep south and gulf of mexico, with the lower-
levels moistening enough to bring pwats up to the 1.25 to 1.50
inch range. This should allow for 10-20% pops, but it will be
very difficult for cumulus to become deep enough to reach the
freezing level (~18k ft) with significant subsidence and dry air
aloft persisting. Therefore thunderstorms chances are less than
10%, as signficant mesoscale forcing would be required to overcome
the unfavorable synoptic environment. That being said, our nearby
land masses will have enough juice to produce deep convection in
the afternoon hours. This combined with favorable southeasterly
flow will allow for lingering outflow boundaries to produce at
least isolated showers and perhaps a thunderstorm or two.

Marine
A small craft advisory remains in effect for all of the coastal
waters of the florida keys. Moderate to fresh easterly breezes
continue as a ridge of high pressure slowly weakens and settles
across central florida. Winds will veer more southeasterly
beginning Tuesday night, with moderate to fresh breezes prevailing
in typical surges and lulls.

Aviation
Vfr conditions will prevail at the eyw and mth island terminals
today. Few to scattered clouds between 2500 and 3500 feet are
expected, but a very dry and stable airmass will prevent any
shower activity. Surface winds have dropped off overnight but will
increase later this morning with gusts around 20 knots.

Climate
On this date in 1899, h. R. Boynton, an observer with the weather
bureau office in key west, recorded details of the occurrence of
numerous waterspouts in the vicinity of the island on the morning
of the 26th. His observations and drawings of the event were
published in the national scientific journal "monthly weather
review".

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.
