Discussion
Currently
Along the island chain, skies are partly cloudy with temperatures
averaging in the lower 80s. Meanwhile, local radars are detecting
only isolated showers and thunderstorms mainly on the straits of
florida. Surface wise, an extensive western atlantic ridge extends
across central florida, resulting in winds varying from 1 knot at
both carysfort reef light and long key light to 8 knots
elsewhere.

Short term (today through Tuesday night)
a deep troposheric anticyclone centered near bermuda with a
lengthy ridge reaching across the central portion of the sunshine
state will strengthen slightly over the next couple of days,
before eroding late in this period. With the position of the
ridge axis, our region will be subject to pockets of higher
moisture migrating westward within a low and mid level easterly
flow. Due to these subtle changes, will stream line low chance
pops through the period due to timing uncertainty. Outside of any
heavy downpours, low temperatures will range between 80 and 85
degrees with high temperatures near or just above 90 degrees.

Long term (Wednesday through Saturday)
the persistent western atlantic ridge axis extending across the
central portion of the florida peninsula will lift slowly
northward and drape across the southeast united states by the end
of next week and into the weekend. Because of this, our area
will lie on the southern periphery of the ridge axis resulting in
a fairly deep easterly flow. However, there are no significant
low level undulations foreseen on the horizon. Regardless, ample
low level moisture within an easterly flow combined with very warm
coastal waters should generate night time showers and isolated
thunderstorms. In addition, with low level winds experiencing
subtle increases and lulls, cells will track toward our area from
the large neighboring land masses along with mesoscale forcing in
the form of wet cloud line genes. Hence, low chance pops will be
retained.

Marine
Gentle to moderate east to southeast winds with the higher winds
expected on the coastal waters south of the island chain are
anticipated for at least the next several days.

Aviation
Vfr conditions will prevail at both eyw and mth terminals.

Additional moisture in the lower and middle levels will move into
the region and provide for vcsh until the afternoon. Afternoon vcts
could bring brief MVFR ceilings and MVFR to ifr visibility
reductions until late afternoon to early evening. Winds will remain
east to southeast near 10 knots.

Climate
In 1929, the daily record low temperature of 72f was last
recorded in key west. Temperature records date back to 1872.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
