Area Forecast Discussion
National Weather Service Key West FL
955 PM EDT Tue Apr 25 2017

.DISCUSSION...
.CURRENTLY...
Local radars are not detecting any precipitation echoes but
considerable false echoes in the form of chaff are covering our
region. Under mostly clear to partly cloudy skies and light winds,
temperatures range between 70 and 74 degrees in the Florida Keys.
Surface wise, a ridge of high pressure is aligned from the north
central Gulf of Mexico to across our area. On our marine district,
winds are west to northwest at less than 10 knots. Otherwise, our
evening sounding reveals scant moisture (PWAT .89 inches) with a
couple of stable layers with the most pronounced 4 degree C one
located at 800 mb. Light northwest winds back and increase quickly
above 925 mb.

&&

.SHORT TERM...(Rest of Tonight)
Despite a subtle mid and upper level disturbance in the eastern
Gulf of Mexico migrating across our area tonight, extremely dry
air should preclude any shower activity. Light and variable winds
early tonight will allow temperatures to drop into the mid and
upper 60s in some interior locations of the larger islands,
elsewhere, low temperatures will average in the lower to mid 70s.

&&

.MARINE...
Light mostly northwest winds of 10 knots or less will clock around
to east to southeast on all Keys coastal waters by morning.

&&

.AVIATION...
Until 12z/26th, VFR conditions will prevail at the Key West and
Marathon terminals. West to northwest winds of less than 10 knots
will turn east at similar speeds overnight.

&&
