Area Forecast Discussion
National Weather Service Key West FL
542 PM EDT THU OCT 6 2016

.DISCUSSION...
.CURRENTLY...
Powerful Hurricane Matthew is located about 110 miles east of Fort
Lauderdale, moving northwest to north near 15 mph. Meanwhile, local
radars are detecting outer rainbands dropping south southwest off the
south Florida peninsula, and into the Middle and Upper Keys and the
adjacent waters. Away from cells, winds are northwest to north
ranging from 15 to 20 knots except 20 to 25 knots on the waters
adjacent to the Middle and Upper Keys.

.SHORT TERM...(Tonight through Sunday night)
Occasional rainbands will affect a good portion of the island chain
for the balance of this afternoon and evening, with the best chance
of rainfall shifting into the Middle and Upper Keys as Hurricane
Matthew lifts primarily toward the northwest. Thereafter, the best
chance for rainfall due to convergent wet cloud boundaries will be on
Friday and Friday evening, before much drier air filters in with only
isolated pops this weekend.

&&

.LONG TERM...(Monday through Thursday)
Given considerable uncertainty amongst reliable medium range
guidance, will retain low chance pops through the period. See
no reason to stray from highs in the upper 80s with overnight lows
near 80 degrees.

&&

.MARINE...
Due to occasional tropical storm wind gusts associated with outer
rainbands, will keep a Tropical storm warning for the coastal waters
adjacent to the Middle and Upper Keys. Elsewhere, a Small Craft
Advisory will remain in effect.

&&

.AVIATION...
Rest of today, For both the Marathon and Key West International
terminals, showers and squalls will develop within rainbands. Brief
IFR/LIFR conditions will be likely within this activity. For the
KEYW terminal, Surface winds from 020 degrees aoa 20 knots, will
back to 350 degrees after 18Z, then to 320 degrees after 00z. At
KMTH terminal, Surface winds from 360 degrees aoa 25 knots, will
back to 320 degree aoa 25 knots by 00z. Convective gusts may reach
40 knots at KMTH.
