Discussion
Currently
Under partly cloudy skies and a steady, albeit light south to
southwest wind near 10 mph, temperatures are hovering in the lower
80s along the island chain. Meanwhile, local radars are detecting
scattered showers and isolated thunderstorms on the nearshore
waters north of the island chain, as well as on the waters in and
around dry tortugas and southward for 60 nm. Elsewhere, isolated
showers are been seen south of the florida keys. On our marine
district, winds are south to southwest ranging from 4 knots at
smith shoal light to 14 knots at alligator reef light.

Short term (today through Tuesday night)
a broad area of low pressure extending from the south central
florida and into the extreme southeast gulf of mexico today will
lift out toward the northeast by tonight. Thereafter, a lengthy
western atlantic high pressure cell aligned across the island of
cuba will lift northward and meander between south florida and our
region Monday through at least Tuesday night. But until then,
plenty of moisture, weak low level confluence and a fairly
favorable low level wind profile should once again allow wet cloud
line genesis. With that, above normal chance pops will be retained
for today. For tonight, a south to southwest steering flow of 10
to 13 knots may allow cells outflow boundaries to migrate off the
archipelago of cuba, and at least approach our area early
tonight. Thereafter, large scale subsidence associated with drier
air should dominate our sensible weather elements beginning
Monday. With that, low chance pops will be kept early tonight,
with isolated 10 to perhaps 20 percent pops for the balance of
this forecast cycle.

Long term (Wednesday through Saturday)
the aforementioned (2nd paragraph) high pressure system is
expected to retrograde westward, as a lengthy tropical upper
tropospheric trough (tutt) migrates westward and approaches our
region by the end of this week and early next weekend. Given an
increase in moisture and instability, chance pops will be kept
during this time frame.

Marine
On the nearshore and offshore waters surrounding the upper keys,
mainly gentle to occasional south to southwest winds can be
expected today, elsewhere, mainly light to gentle winds will
prevail. For tonight, south to southwest winds of 10 knots or less
are anticipated. For the upcoming week, mainly west to northwest
winds of 10 knots or less should predominate, before becoming
variable and then southeast by end of this week.

Aviation
Convection has redeveloped during the late night hours along
lingering boundaries around the florida keys, and this activity may
directly impact either terminal with sub-vfr conditions during the
predawn and early morning hours. Later today, an island cloud line
may develop, but predicted SW low level flow should displace it
slightly north of the island chain, and therefore have included only
vcsh for both terminals, withVFR conditions prevailing.

Climate
In 2012, the daily record low temperature of 72 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.
