Area Forecast Discussion
National Weather Service Key West FL
323 AM EDT Wed Mar 29 2017

A large area of chaff in the western portion of the Keys service
area has settled out of the radar scope over the past hour or so.
Migrating northbound birds have become the dominant echo return
over the past two hours. There are no precipitation echoes to be
found on KBYX doppler radar presently. Winds are gentle to
moderate from the east/southeast, and temperatures are in the
lower 70s.

Ridging will continue nearby through the middle and upper levels
of the troposphere. High surface pressure currently stretched
across the Florida peninsula will ease eastward over the next
couple of days. Winds will remain gentle to moderate from the
east/southeast today and tonight, accelerating and turning more
southeasterly Thursday and Thursday night, well ahead of a
weakening front sagging that should stall to our north by late
Friday. Broad but relatively weak high pressure becomes realigned
across the state through the weekend. In general, no major
adjustments were necessary to the gridded weather data this
morning. Will keep the forecast POP-free through Friday, then
carry just a minimal chance as our flow turns more to the south,
then weakens through the weekends. Expect temperature at or just
above the seasonal average over the next few periods, gaining
several degrees into the weekend and into early next week.


No cautionary or advisory headlines for any of the coastal waters
surrounding the Florida Keys on this forecast thanks to broad high
pressure north of our area through late tonight. A weak front will
wash out north of the Keys on Friday, followed by a weak pattern
through the weekend.


Expecting a few hours of MVFR ceilings due to developing island
cloud lines after 29/19z. Until then, then after 30/01z, VFR
conditions will prevail at both the Key West and Marathon
International terminals. Winds will be mainly east, less than 10
