Area Forecast Discussion

.DISCUSSION...
.CURRENTLY...
Under partly cloudy skies and northeast to east winds of 10 to 15
mph, temperatures are hovering around 80 degrees. Meanwhile,
local radars are detecting scattered showers on the offshore
waters of Mainland Monroe, with only a few showers elsewhere.
Surface wise, a large area of high pressure is centered over the
Mid Atlantic coast, with a stationary boundary aligned across
south Florida and the adjacent Gulf and Atlantic Ocean. On our
marine district, northeast to east winds are near 15
knots. Otherwise, our evening sounding reveals an increase in 
moisture (PW 1.77 inches) within a decoupled flow. A fresh 
easterly flow reaches up to 700 mb before turning quickly westerly
above.

&&

.SHORT TERM...(Rest of tonight)
Moisture below 700 mb will be on the increase due to an
accelerating northeast to east flow. With that, enhanced moisture
flux and low level confluence supports chance pops. Under 
changeable skies and northeast to east winds of 10 to 15 mph, low 
temperatures will range between 75 and 80 degrees. 

&&

.MARINE...
Outside of Florida Bay and the nearshore Gulf waters north of the
Lower and Middle Keys, a Small Craft Should Exercise Caution
headline for increasing winds will be kept in place. 

&&

.AVIATION...
Until 12z/12th, outside of a brief MVFR spell, 
VFR conditions will prevail at the Key West and Marathon
terminals. Northeast to east winds will range between 10 and
15 knots. 

&&

.KEY WATCHES/WARNINGS/ADVISORIES...
FL...None.
GM...None.
