Area Forecast Discussion
National Weather Service Key West FL
941 PM EDT Sat Oct 22 2016

.CURRENTLY...Skies have been clearing out after the FROPA earlier
today bringing breezy CAA through the Florida Keys. Temperatures at
WFO Key West and Marathon International Airport have reflected this
and are sitting in the mid 70s with comfortable dewpoints in the mid
50s. As for radar, KBYX is showing a large area of birds in the form
of biological echoes. No precipitation at this time.

.SHORT TERM... Forecast changes were minimal this evening. Focused
primarily on winds and temperatures this update. This evenings
sounding shows subsidence continuing to prevail, with a stable and
relatively dry airmass in place. Winds have increased in our eastern
CWA and continue to hold up across our Western waters so a Small
Craft Advisory was expanded in time and area to accommodate this.


.MARINE...The Small Craft Advisory has been updated in area to
include our entire CWA and extended in time until tomorrow afternoon.
A large area of high pressure over the southeastern United States
will continue to generate fresh to strong north to northeast breezes
from tonight through Thursday.


North breezes are freshening across the island chain at this hour.
These winds will turn to the northeast through Sunday morning,
maintaining a moderate crosswind component. Expect the surface winds
to gust near or slightly above 20 knots. Otherwise, visibility and
sky conditions will be VFR at the KEYW and KMTH terminals.


The last time temperatures in Key West dipped below 70 degrees dates
back to May the 8th 2016, some 167 days ago. The average date for
such an occurrence is October 28th. Temperature records in Key West
date back to 1872. &&
