Area forecast discussion, Jan 12, 9:10 PM EST, 7 hours 14 minutes before
Area Forecast Discussion
National Weather Service Key West FL
910 PM EST Fri Jan 12 2018

.DISCUSSION...
.CURRENTLY...
KBYX detects widely separated showers throughout the forecast
area. Skies over the island chain are partly cloudy. Winds over
land are west near 10 mph. C-MAN winds, on average, are west to
northwest at 10 to 15 knots. Temperatures are in the lower to mid
70s.

.SHORT TERM (Overnight)...
A cold front will pass through the Florida Keys after midnight
tonight. The 00z KKEY sounding is moderately unstable and
seasonably moist, with a precipitable water (PWAT) value just
under one and one quarter of an inch. Atmospheric moisture will
decrease overnight. By sunrise Saturday, PWAT values will be just
under one inch, which is near the 25th percentile for this time
of year. No more than slight chance POPs are needed overnight
ahead of and along the aforementioned cold front.

.MARINE...
Moderate northwest breezes will prevail on all Keys coastal waters
overnight. No advisories expected tonight. A Small Craft Advisory
