Discussion
Currently
Kbyx detects no precipitation echoes. Skies over the island chain
are mostly sunny. Winds over land are south at 5 to 10 mph. C-man
winds, on average, are southeast to south near 10 knots.

Temperatures are near 80 degrees.

Short term (this afternoon)
In the low levels of the atmosphere, an atlantic ridge of high
pressure will extend across central florida this afternoon. In the
mid levels of the atmosphere, an atlantic ridge of high pressure
will extend across south florida today. In the upper levels of the
atmosphere, a ridge of high pressure will be located just east of
the florida peninsula this afternoon. The 12z kkey sounding is
very unstable and quite dry for this time of year, with a
precipitable water (pwat) value just above one inch. Atmospheric
moisture will increase this afternoon. By sunset this evening,
pwat values will be just under one and one quarter of an inch,
which is still below normal for the end of april. The relatively
dry air mass in place will be responsible for no chance of rain
today.

Marine
Gentle southeast to south breezes will prevail on all keys coastal
waters this afternoon. No advisories expected today and tonight. A
small craft advisory may be required for the coastal waters of the
florida straits Friday. A small craft advisory will likely be
required for the coastal waters of the gulf of mexico and atlantic
Friday night. A small craft advisory may be required for the
coastal waters of florida bay Friday night. A small craft advisory
will likely be required for all keys coastal waters Saturday
through Sunday night. A small craft advisory may be required for
the coastal waters of the florida straits Monday. No advisories
expected Monday night.

Aviation
Vfr conditions will prevail at both the key west and marathon
international terminals through at least 28/06z. South winds this
morning will back to southeast, then east at around 10 knots
through 00z this evening.

Climate
On this date in florida keys weather history, in 2003, a severe
thunderstorm produced a 53 mph wind gust at key west international
airport, along with hail, varying in size from a marble (one half
inch in diameter) to a golf ball (one and three quarters of an
inch in diameter). This is the largest hail ever measured at key
west international airport. In addition, this is tied as the
largest hail ever observed in monroe county.

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.
