Area Forecast Discussion
National Weather Service Key West FL
954 PM EDT Sun May 28 2017

Temperatures across the island chain range from 84 to 86 degrees
as of 9pm under mostly clear skies. A cloud line, that formed
across the Florida Keys and spawned at least one waterspout, and a
separate short-lived thunderstorm near Boca Chica, drifted south
of the islands after sunset. Remnants of this line can be seen via
infrared satellite but it is nearly completely eroded at this
time. Dew points are in the mid 70s. CWOP stations report
variable winds near 5 mph. Across our marine district, CMAN
stations report variable winds of 5 to 10 knots. The Pulley Ridge
Buoy reports seas of 2 ft.

A ridge axis will settle across the Florida Keys, stretching from
the Southeastern Gulf, to the Middle Keys, to Andros in the
Bahamas. This will keep light and variable winds, with a low
chance of showers overnight. Temperatures will gradually dip
overnight to near 80, but with light winds under mostly clear
skies, a few normally cooler locations may be able to fall to the
mid 70s. Isolated showers may be possible Monday with a gradual
moistening in the low levels. Otherwise, the forecast remains in
track with a steady increase in moisture and probabilities of deep
convection in the extended timeframe - 30 percent will do for now.


Light to gentle breezes will continue early this week, creating
pleasant marine conditions. No advisories or warnings are in
place. Winds will begin to freshen out of the east mid-week,
creating periods of 15 to 20 knot winds across the Atlantic


VFR conditions will prevail at EYW and MTH much of tonight. MVFR
conditions are conceivable at EYW and MTH after 09z through Monday
morning. This possibility is not great enough to place in the
terminal forecasts at this time. VFR conditions will prevail at EYW
and MTH Monday afternoon. Sustained north winds of 5 to 10 knots
from just off the surface to about 3,000 feet will veer to east to
southeast and increase to 10 to 15 knots late tonight.


The low temperature so far today at Key West International Airport
is 81 degrees. This would tie the daily record for warmest minimum
temperature ever measured in Key West on May 28th. The current
record of 81 degrees was set in 1924. Temperature records at Key
West date back to 1872.
