Discussion
Currently
Kbyx detects isolated showers throughout the forecast area. Skies
over the island chain are partly cloudy. Winds over land are east
to southeast at 15 to 20 mph. C-man winds, on average, are
southeast near 20 knots. Temperatures are in the lower 80s.

Short term (this afternoon)
In the low to mid levels of atmosphere, a large area of high
pressure will be centered over the western atlantic ocean, east of
the carolinas, this afternoon. In the upper levels of the
atmosphere, a ridge of high pressure will be located just east of
the florida peninsula today. The 12z kkey sounding is moderately
unstable and seasonably moist, with a precipitable water (pwat)
value just under one and one half of an inch. Atmospheric moisture
will decrease this afternoon. By sunset this evening, pwat values
will be just above one and one quarter of an inch, which is near
normal for the end of april. Large scale subsidence will be
responsible for no more than slight chance pops today.

Marine
A small craft advisory is in effect for all keys coastal waters
this afternoon due to sustained east to southeast surface winds
near 20 knots. A small craft advisory will likely be required for
all keys coastal waters tonight. A small craft advisory may be
required for the coastal waters of the florida straits Monday. No
advisories expected Monday night through at least Thursday night.

Aviation
Vfr conditions are expected at the island terminals this
afternoon. Surface winds will be east to southeast at 10 to 15
knots, with gusts near 25 knots.

Climate
On this date in florida keys weather history, in 1992, the low
temperature at key west international airport was 59 degrees. This
set the daily record for minimum temperature measured in key west

records at key west date back to 1872.

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. 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.
