Area Forecast Discussion
National Weather Service Key West FL
1052 PM EDT TUE JUN 7 2016

.DISCUSSION...
Changes to Forecast -- The Small Craft Advisory was cancelled for
all zones.  Minor adjustments were made to wind, wave heights,
weather, sky cover, and qpf.

Current Situation and Analysis -- the Florida Keys and adjacent
coastal waters are within a larger area of deep, moist, unstable,
confluent southwesterly flow.  Data from the Key West evening
radiosonde balloon indicated a very moist, moderately unstable, and
weakly sheared atmosphere with little or no convective inhibition.
Not surprisingly, numerous showers and a few thunderstorms have
been developing across the area this evening.  Cell movement
definitely has slowed since this afternoon.  Currently, skies are
cloudy across the Florida Keys, with air temperatures near 80F,
and dewpoint temperatures in the mid 70s.

.SHORT TERM...
Forecasts have been adjusted, but overall shower/storm coverage
and rain chances have been kept at numerous/70 percent overnight,
given radar trends and latest observations/guidance.
&&

.MARINE...
Small craft should exercise caution all zones until winds and seas
subside.  An Atlantic ridge of high pressure will move northward
from the western Caribbean Sea to the Florida peninsula overnight
through Friday.  The ridge then will weaken Saturday and Sunday.
&&

.AVIATION...
Overnight, on balance, expect VFR CIGS at both the EYW AND MTH
island terminals, with bases aoa FL030-050 & FL080-100, but do
expect occasional mvfr cigs in showers with bases AOA FL015-020.

Otherwise expect crosswinds from 200-220 degrees averaging 9-13
knots with with gusts between 18 and 25 knots.
