.DISCUSSION...
.CURRENTLY...
Early visible satellite photographs show skies are partly to
mostly sunny with temperatures in the mid to upper 80s in the
Florida Keys. Meanwhile, local radars are not detecting any
significant precipitation echoes in our region. Surface wise, our
area is between a strong tropical wave in the western Caribbean
sea, an elongating tropical wave in the extreme southeast Bahamas
and a formidable western Atlantic ridge aligned well north of our
region. On our marine district, winds are east at 15 to 20 knots
and gusty. Otherwise, our morning sounding reveals scant moisture
(PWAT 1.30 inches) below 900 mb within a deep tropospheric
easterly flow.

&&

.SHORT TERM...(Rest of today)
Unusually dry air will prevail along the entire island chain with
east winds of 10 to 20 mph. Temperatures will reach into the lower
90s in many communities with only isolated dime pops.

&&

.MARINE...
Fresh to occasional strong east winds will slacken a tad this
afternoon, before abating late tonight and especially on Tuesday.
But until then, A Small Craft Should Exercise Caution headline
will be required on most Keys coastal waters.

&&

.AVIATION...
Until 00z/22nd, outside of possible brief MVFR ceiling, VFR
conditions will prevail at the Key West and Marathon terminals.
Mostly east winds of 10 to 15 knots will gusts to near 20 knots.

&&

.CLIMATE...
In 1923, the daily record low temperature of 71 degrees was
recorded in Key West. Temperature records have been kept since
1872.

&&

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