Discussion
Currently
Kbyx detects no precipitation echoes in the forecast area. Skies
over the island chain are partly cloudy. Winds over land are
northeast near 5 mph. C-man winds, on average, are northeast to
east at 5 to 10 knots. Temperatures are in the mid 80s.

Short term (overnight)
In the low levels of the atmosphere, a feeble atlantic ridge of
high pressure will extend across central florida overnight. In the
mid levels of the atmosphere, an area of high pressure will be
centered over the northern gulf of mexico tonight. In the upper
levels of the atmosphere, a weak trough of low pressure will be
located over the bahamas overnight. The 00z kkey sounding is very
unstable and moist for this time of year, with a precipitable
water (pwat) value just above one and three quarters of an inch.

Atmospheric moisture will decrease overnight. By sunrise Saturday,
pwat values will be just above one and one half of an inch, which
is near normal for the end of may. This decrease in atmospheric
moisture should limit pops to slight chance category overnight.

Marine
Light to gentle northeast to east breezes will prevail on all
keys coastal waters overnight. No advisories or cautionary
headlines expected tonight through Tuesday. Small craft are urged
to exercise caution on the coastal waters of the florida straits
Tuesday night through Wednesday night due to sustained east to
southeast surface winds of 15 to 20 knots.

Aviation
Vfr conditions will prevail at eyw and mth through at least
Saturday afternoon. Light and variable breezes are expected
overnight, with gentle easterly breezes near 8 knots picking up
late Saturday morning.

Climate
On this date in 1899, h. R. Boynton, an observer with the weather
bureau office in key west, recorded details of the occurrence of
numerous waterspouts in the vicinity of the island in the morning.

His observations and drawings of the event were published in the
national scientific journal "monthly weather review".

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.
