Discussion
Currently
Under partly cloudy skies and light northeast to east winds of
less than 10 mph, temperatures are hovering around 80 degrees
along the island chain. Meanwhile, local radars are only detecting
isolated showers primarily on the straits of florida. On our
marine district, winds are north to northeast ranging from 6 knots
at carysfort reef light to 9 knots at alligator reef light.

Short term (today through Sunday night)
a broad area of low pressure near andros island early this
morning, will move northwestward and over south florida this
evening before lifting north northeastward to offshore of the
northeast florida coast late Saturday. Meanwhile, a high pressure
cell will build across the archipelago of cuba, and then northward
into the straits of florida on Sunday night. Precipitation wise,
despite the majority of the mid and upper level ascent remaining
to our northeast, ample moisture, weak low level confluence and
activity migrating southward off the south florida mainland will
prompt high chance pops through at least this evening. Beyond
that, drier air will slowly filter into our region during this
weekend. However, a light wind regime combined with ample low
level moisture should allow mesoscale forcing in the form of wet
cloud line genesis and cells moving off the large land masses
surrounding our area. Hence, 30 to 40 percent pops will be
inserted for this weekend.

Long term (Monday through Thursday)
a western atlantic high pressure system will meander between the
north coast of the island of cuba and south florida through mid
week, before lower pressure presses southward over the eastern
gulf of mexico and the sunshine state toward the end of next week.

Subsequently, low chance climo pops will be retained through the
period. High temperatures will average in the lower 90s with
overnight lows generally in the lower 80s.

Marine
Outside of heavier showers, thunderstorms or outflow boundaries,
gentle winds will predominate on all keys coastal waters for at
least the next several days. Therefore, no headlines will be
needed for our entire marine district.

Aviation
Vfr conditions will prevail today at the eyw and mth terminals, as a
weak low pressure area moves across the eastern straits of florida
into the southeastern florida coast. Brief periods of MVFR or ifr
conditions will be possible in passing showers. The surface low will
provide weak N NE low level flow across the keys, which may steer
convection and associated outflows from the mainland toward the
terminals during the afternoon evening hours, but uncertainty is too
high to mention anything more than vcsh at this time.

Climate
In 1913, the daily record low temperature of 71 degrees was last
recorded in key west. Temperature records 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.
