Area Forecast Discussion
National Weather Service Key West FL
351 AM EDT Mon Mar 27 2017

.DISCUSSION...
Under mostly clear skies with a light to moderate easterly breeze,
temperatures along the Keys island chain are in the lower to mid
70s. KBYX radar is void of precipitation echoes.

A broad area of high surface pressure centered in the western
Atlantic currently extends across the southeast coast and northern
Florida. The center of the high pressure will settle southward, to
the east of the Florida peninsula tomorrow through Wednesday. The
local area will see a steady gentle to occasionally moderate
easterly flow under a low amplitude mid level ridge stretching
eastward from the Gulf of Mexico. That ridge does flatten later
in the week while the lower flow veers southeasterly. However, the
latest guidance suggests that the overall moisture later this week
is actually lower than presently. The only change made to the
gridded elements for this forecast cycle was to remove the minimal
mention of showers for late this workweek into the coming weekend.
The latest extended GFS MOS numbers are either in or very close to
single digits as far as POPs are concerned, giving an elevated
level of confidence for that decision. Basically, the entire
forecast has no mention of measurable precipitation. Temperatures
will be at or slightly above the seasonal average through the
middle of the week, then adding a few degrees later in the week
and into the weekend.

&&

.MARINE...
Expect relatively pleasant recreational boating conditions over
most waters surrounding the Florida Keys this week. Winds will be
mainly from the east, ranging from gentle to occasionally
moderate. No cautionary or advisory headlines for small craft are
expected this week.

&&

.AVIATION...
VFR conditions with generally east northeast to east breezes will
prevail at the EYW and MTH terminals today.

&&

.CLIMATE...
On this date in 1994, the daily record high temperature of 87F was
last recorded in Key West. Temperature records for Key West date
back to 1872.
