Area Forecast Discussion
National Weather Service Key West FL
250 PM EST Thu Feb 9 2017

.DISCUSSION...
.CURRENTLY...
A weak cold front, associated with a narrow band of showers, is
located over south central Florida and the adjacent Atlantic and
Gulf waters. Ahead of this boundary, light westerly winds with
considerable sunshine is allowing temperatures to rise between 80
and 85 degrees along the island chain.

&&

.SHORT TERM...(Tonight through Sunday night)
A weak cold front will lying across south central Florida and the
adjacent Atlantic and Gulf waters will drive southeastward and
cross our entire county warning area late this afternoon and
evening. This frontal boundary will be accompanied by a broken
band of showers with little if any measurable rainfall anticipated
along the island chain. Meanwhile, a large region of high pressure
over the nations midsection will migrate swiftly into the
Southeast United States Friday, with an extensive ridge will reach
across the Sunshine State this weekend. With that said, nickle to
perhaps dime pops at best will be carried through this time
period. Given a predominate atlantic trajectory, only subtle
cooling but with dewpoint readings about 10 degrees lower can be
expected.

&&

.LONG TERM...(Monday through Thursday)
Medium range guidance has begun to diverge somewhat with the
extent and timing of a cold front pushing through the Gulf of
Mexico and the Florida peninsula the latter part of next week. But
until then, only nickle pops with slightly above normal
temperatures will be retained through Wednesday. Thereafter,
isolated dime pops will be carried.

&&

.MARINE...
Since winds will become sustained near 20 knots or higher late
tonight and after midnight, a Small Craft Advisory will be hoisted
for all Keys coastal waters beginning with the 430 pm marine
package. With that said, fresh to strong northeast winds Friday
morning will slacken some on Friday afternoon before a subtle
surge overspreads our waters by evening. Thereafter, fresh to
occasional strong east winds will abate later Saturday but
especially on Sunday.

&&

.AVIATION...
VFR conditions will prevail for the rest of the day at both the Key
West and Marathon terminals. A cold front is moving down the Florida
Peninsula and will result in increasing winds to around 10 knots
while turning to the north by 09/23z.  Cold air will arrive with a
wind surge and slight crosswind considerations especially in gusts
after 10/09z.

&&

.CLIMATE...
In 1995, the daily record low temperature of 48 degrees was
recorded in Key West. Temperature records have been kept since
1872.

&&

.PRELIMINARY POINT TEMPS/POPS...
Key West  69  75  67  78 / -  -  -  -
Marathon  68  77  67  78 / -  -  -  -
