Discussion
Currently
Light northerly flow and patchy cloud cover are present, with a
hint of a cloud line developing near big pine key and the middle
keys. Kbyx detects only chaff surrounding the florida keys.

Current temperatures are in the upper 70s to low 80s. Dew points
are in the mid 60s.

Forecast
In the short term, decreasing cloud cover with winds becoming
calm overnight may lead to a radiational cooling event, though
warm nearshore waters in the upper 70s to low 80s will prevent our
temperatures from dropping to the dew points (forecasted to be in
the low 60s). In general, expect a low near 70, though certain
spots in the upper keys and big pine key could see upper 60s. If
the winds fail to go calm - expect low to middle 70s.

A longwave trough will stay planted in the eastern conus, as a
series of upper level disturbances dig into the southeast and lift
to the northeast thereafter. Thereafter, the parent vortex in the
great lakes region shifts the complex to new england late
weekend, and into the northwestern atlantic early next week. A
longwave ridge will then set up across the eastern CONUS as a new
trough slides through the upper midwest midweek. Large differences
currently exist between gfs ECMWF as early as tomorrow night, as
it all depends on the eventual northward drift of the stalled
boundary currently south of the keys. ECMWF is quite rain-
optimistic at this point, and the GFS is very dry - which is the
opposite of the normal bias of each. As a result, had to re-
introduce showers into the forecast beginning tomorrow night, and
adjust the scattered wording this weekend. Because of the high
differences, confidence is lower than average of the eventual
pattern - stay tuned.

Marine
No watches, warnings, or advisories are in effect for the waters
surrounding the florida keys. A weak pressure gradient will
prevail for the balance of this week and into the weekend before a
large and strengthening area of high pressure gradually builds
into our region from the north late this weekend.

Aviation
Vfr and light breezes will prevail at the eyw and mth terminals
through the evening.

Climate
April 25th, on this date in key west climate history, in 1991, the
daily record high temperature of 90f was recorded. The high
temperature so far today is 83f. Temperature records in key west
date back to 1872.

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.
