Discussion
Temperatures this morning are near 80 degrees along the island
chain, with dew points in the lower 70s. East to southeast breezes
have come down to near 10 knots in the past couple of hours, with
mostly clear skies indicated by goes-east imagery and only a brief
isolated shower or two being detected by key west weather radar.

A relatively straightforward forecast for the keys, as a highly
anomalous upper-level ridge begins to build across the southeastern
united states today. This ridge will largely control our sensible
weather for the next week, as surface high pressure builds into
our northeast in wake of the remnants of subtropical storm andrea.

This will lead to a period of freshening east to northeasterly
breezes beginning tonight and continuing through Sunday night.

Pops through the forecast period will remain isolated, with
slightly higher chances tonight and tomorrow night in association
with wind surges favoring isentropic ascent in the low-levels.

Chances for thunder are practically zero, as mid-level subsidence
and dry air keeps updrafts from climbing above the freezing level.

Day 6 to 7 begins to introduce more uncertainty, as the ECMWF and
gfs differ on the rate of weakening of the ridge axis. As a result
ensemble solutions also begin to diverge, with the eps insistent
on restrengthening an upper-level ridge over the gulf of mexico.

The GEFS however is more suppressed with the upper-level ridge.

Either way it looks to remain warm and relatively dry through the
next 7 days, with the consequences of the upper pattern becoming
more relevant beyond day 7.

Marine
No watches, warnings, or advisories are currently in effect for
the coastal waters of the florida keys. Easterly winds will
freshen tonight and small craft advisories likely will be required
for portions of the coastal waters, particularly in the florida
straits and hawk channel. Although some lulls are expected, small
craft advisories are expected to continue for portions of the
waters through Sunday night as fresh to strong east to
northeasterly breezes continue. Winds are expected to slacken
early next week, with high uncertainty in regard to the magnitude
of decreasing.

Aviation
Until 00z 23rd,VFR conditions are anticipated at the key west and
marathon terminals. East to southeast winds of 10 knots or less will
increase to 10 to 15 knots with gusts near 20 knots this evening.

Climate
On this date in 1997, an f1 tornado produced damage around mile
marker 58 on grassy key. No injuries or fatalities were reported.

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.
