558 am edt Mon oct 23 2017

Currently
Partly cloudy skies lay overhead of the florida keys early this
morning with isolated shower coverage mainly across the middle and
upper keys, with more scattered coverage found in the vicinity of
the dry tortugas, extending southward across the western florida
straits. A majority of the shower activity affecting the island
communities have only been able to deliver minor accumulations,
if any at all. Temperatures are hovering near record warm low
values (81f for key west), likely owing to the moderate
southeasterly breezes of 10 to 15 mph measured at our land
observing sites. Over the water, winds across the straits and hawk
channel have been averaging 15 to 20 knots, and a hair less over
the gulf waters to our north.

Short term (today through Wednesday)
The ridge of high pressure that has been extended down the
eastern portion of the u.S. The last few days has begun moving off
to the northeast. This will all the pressure gradient to weaken
across our area, allowing winds to slacken and drop below advisory
criteria. This ridge is moving off to the northeast as a response
to the aforementioned cold front moving eastward toward the mid-
atlantic and the southeastern states.

Ahead of this front, atleast for today and tonight, we can expect
slightly above normal rain chances, favoring the western portion
of the cwa. Winds currently out of the southeast will start to
clock around to the south Tuesday and southwest to west Tuesday
night, albeit light to gentle. Temperatures will remain slightly
above normal for late october ahead of the front, along with moist
dewpoints in the middle 70s.

Model guidance has trended a bit later with the frontal passage,
now favoring early Wednesday morning for the keys, with some
timing differences still existing between the GFS (earlier) &
ecmwf (later). The best upper level dynamics seem to lag well
behind the initial push with the frontal passage, so while an
increase in rain chances to likely is forecast, do not see the
support for a strong squall line to accompany the front, with the
primary fanfare being a strong wind surge Wednesday morning.

One welcomed gift the front will deliver to the florida keys is a
sizable drop in dewpoints, with values dipping in to the lower
60s by Wednesday evening. Skies should clear throughout the day on
Wednesday, and winds will remain breezy out of the north.

Long term (Wednesday night through Sunday) in the wake of the
front, conditions will dry out significantly with very
comfortable dewpoints in the upper 50s to low 60s Wednesday night
and during the day on Thursday. Temperatures will settle down in
to the middle 60s for most island communities early Thursday
morning, with daytime highs topping out in the mid-upper 70s.

We will start to recover to more typical october weather pattern
on Friday as moisture returns from the south, and by Friday night
dewpoints are back in to the 70s once again. Both the GFS ecmwf
show decent moisture streaming back across the keys Friday night
and in to Saturday as another trough digs in to the gulf of mexico
and a broad area of low pressure looks to develop across west
central cuba, moving to the north northeast. At this time, this
scenario will atleast result in increased rain chances for the
florida keys for the first half of the weekend before the trough
pushes eastward on Sunday, bringing a more comfortable airmass
once again to the keys. Confidence in this scenario and timing is
low at this point, but we will continue to iron out the details
the next few days, stay tuned.

Marine
A ridge of high pressure extending down the eastern seaboard will
migrate to the northeast today, allowing winds to slacken across
the florida keys. A cold front is slated to press through the
florida keys early Wednesday morning, ushering in moderate to
fresh northerly breezes in its wake. Small craft advisory
headlines will likely be inserted in to the forecast starting
Tuesday night and continuing through Wednesday night.

Aviation
Vfr conditions are expected most of today at both terminals. Shra
will be possible, reducing visibilities at times. Winds will be
generally from the southeast at around 10 knots with gusts up to 20
knots early in the morning, decreasing through the day.

Climate
In 2005, a violent waterspout passed just west of key west in the
outermost rainband of approaching hurricane wilma.
