Area Forecast Discussion
National Weather Service Key West FL
404 PM EST Mon Feb 6 2017

.DISCUSSION...
Key West Doppler radar base reflectivity data have shown a slow-
moving, persistent area of showers, some heavy, drifting
northwestward across the Straits of Florida, Florida Reefs, and
Hawk Channel adjacent to the lower Florida Keys.  In fact areas of
rain now are approaching Sugarloaf Key, Cudjoe Key, and Little Palm
Island.  The showers apparently are associated with a mesoscale
wind surge and low-level moisture maximum.  Surrounding areas
look convectively suppressed per satellite images.  In any case,
we have increased evening sky cover and rain chances for lower
Keys communities.  Please consult Short Term Forecasts for details
on timing and impacts from these showers.

The overall large-scale weather pattern is similar to this morning
and yesterday, with nearly zonal flow at upper levels prevailing
over most of the continental United States and weak ridging
over the Gulf basin and Florida Peninsula.  At the surface, a
high pressure ridge extends from the western North Atlantic to the
western Gulf basin.  After tonight, this ridge should move slowly
southward toward the Florida Keys.  Thereafter, forecast confidence
is slowly increasing with respect to a brief cooldown associated
with a frontal passage sometime between Thursday late afternoon and
Friday early morning.  We should be able to hone in on an accurate
temperature forecast during the forecast cycles spanning the next
few days.  The front will have basically no upper-level support,
with both deep moisture and large-scale forcing for ascent missing.
In fact, the best rain chances over the next seven days really
are in the next six hours with the aforementioned mesoscale
disturbance.
&&

.MARINE...
A Small Craft Advisory will be going into effect shortly for the
lower Straits of Florida, from the west end of the Seven Mile Bridge
to west of Dry Tortugas.  In these zones, we expect east to
southeast winds near 20 knots and significant wave heights up to
seven feet in the Florida Current/Gulf Stream (the core of which is
approaching 4 knots in the lower Straits).  A high pressure ridge
extending from the western North Atlantic to the Texas coast will
move slowly southward from tonight through Wednesday night.  As
a result, northeast to east breezes will turn east to southeast
and gradually diminish.  A developing trough and cold front
likely will move across the Florida Keys and adjacent coastal
waters Thursday night, with a period of strong breezes looking
increasingly likely from Thursday night through Friday night.
&&

.AVIATION...
Scattered showers will approach the KEYW Int'l terminal thru 24
Zulu. Brief mvfr/ifr cigs and/or vis will be likely when these
showers reach the airfield. VFR conditions at KMTH thru 24 Zulu.
Thereafter, VFR conditions will prevail at both EYW and MTH
terminals thru 12 Zulu with winds from 100 degrees aoa 7-10 knots.
