Area Forecast Discussion
National Weather Service Key West FL
212 PM EDT TUE JUL 26 2016

.DISCUSSION...
.CURRENTLY...
KBYX detects isolated showers over offshore waters surrounding the
Florida Keys. Elsewhere, KBYX detects no precipitation echoes in the
remainder of the forecast area. Skies over the island chain are
partly cloudy. Winds over land are east near 15 mph. C-MAN winds, on
average, are east to southeast near 15 knots. Temperatures are near
90 degrees.

.SHORT TERM (Tonight through Thursday night)...
An Atlantic ridge of high pressure will extend across central Florida
tonight through Thursday night. An area of enhanced atmospheric
moisture near the southern tip of Andros Island will pass thorugh
the Florida Keys after midnight tonight. A second region of enhanced
atmospheric moisture near the Dominican Republic should move over
the service area Wednesday night. As a result, rain chances in the
short term portion of the forecast should be highest after midnight
tonight and Wednesday night. A drier air mass should move over the
Florida Keys Thursday night.

&&

.LONG TERM (Friday through Tuesday)...
An Atlantic ridge of high pressure will extend across central Florida
Friday through Monday. This ridge of high pressure should retreat
eastward Monday night and Tuesday. The aforementioned drier air mass
should remain over the Florida Keys Friday and Friday night. The
Saturday through Tuesday portion of the forecast will be based on
climatology as no discernible low level disturbances are expected to
impact the forecast area.

&&

.MARINE...
Moderate east to southeast breezes will prevail on all Keys coastal
waters tonight. No advisories expected tonight and Wednesday morning.
A small craft advisory may be required for the coastal waters of the
Florida Straits Wednesday afternoon and Wednesday night. No
advisories expected Thursday through at least Sunday night.

&&

.AVIATION...
Prevailing VFR conditions are expected through the end of the
forecast period. Model guidance is in good consensus with an
increase in atmospheric moisture after midnight, thus have
introduced VCSH at both island terminals. Any passing shower or
thunderstorm will be capable of producing brief periods of MVFR
CIG/VIS, and will allow amendments to handle those appropriately as
confidence in timing is too low at this point. Winds will remain
easterly, becoming gusty from mid-morning Wednesday and onward.

&&

.CLIMATE...
Nine years ago today, back in the year 2007, the low temperature in
Key West dipped to only 87F. This holds as the warmest daily low
temperature for this date, and for the entire month of July.
Temperature records in Key West date back to 1872.
