Area Forecast Discussion
National Weather Service Key West FL
1036 PM EDT Fri May 24 2019

Currently - Deep layered ridging remains anchored over the
southeastern United States with a surface ridge along down the
Atlantic and Gulf Coasts. This is resulting in moderate to fresh
east northeast breezes across the Keys and surrounding waters. The
ridging has placed a stable environment across the area, and
showers are unable to form. This evenings sounding indicated a
substantial subsidence inversion with copious dry air aloft. Skies
are a mix of mostly clear to partly cloudy due to bands of low
topped stratocumulus streaming across the area.

Short Term Update - Large scale ridging will continue to dominate
Keys weather through the overnight period. Expect moderate to
fresh northeast to east breezes across the island chain. Also
expect rain free conditions and temperatures remaining about where
they are, broadly near 80, due to good ventilation.


High pressure to our north will maintain moderate to fresh
northeast to east breezes across Keys waters through the overnight
period. A small craft advisory remains in effect for all Keys
waters tonight. Only minor adjustments made to first period wind
transitions in the evening marine update.


VFR conditions will prevail at the EYW and MTH island terminals
overnight and Saturday. Scattered to occasionally broken clouds
between 3500 and 4000 feet are expected, but a very dry and stable
airmass will prevent any shower activity. Surface winds will
generally remain from the ENE at 10 to 15 knots with gusts around 20
knots, although winds may drop off somewhat late tonight into early
Saturday morning.
