Area Forecast Discussion
National Weather Service Key West FL
946 AM EDT Tue Apr 25 2017

.DISCUSSION...
.CURRENTLY...
A robust area of low pressure is moving northward along the
Carolina coast this morning, and is the parent low for the front
that passed over the Keys area last evening. High pressure has
moved over the Central Gulf of Mexico in the wake of the front.
Winds are out of the west near 5 knots at the island terminals,
and near 10 knots at the marine reporting stations surrounding the
Island Chain. Skies are mostly clear.

.FORECAST...
Lower dew point temperatures will make the heating of the day seem
quite comfortable today as the ambient temperature rises to near
80 degrees. The high pressure over the Gulf of Mexico will slide
across the Keys area and the Florida Peninsula today through
Wednesday. Winds will turn east to southeast allowing warmer air
to advect over the area returning daily maximums to the mid 80`s
by Wednesday and through the weekend. Helping the warm air to move
northward will be a trough moving across the easter United States
Wednesday night and Thursday. High pressure over the Atlantic will
strengthen resulting in increasing east to southeast winds on
Friday. Expecting fresh winds Friday night through Sunday night,
but rain chances will be low due to stable air aloft. The next
trough will dig through the Colorado Front Range on Sunday night,
then lift quickly northeastward. As the trough lifts out, a
weakening frontal zone will decay north of the area. High pressure
will move over the southeastern Gulf of Mexico resulting gentle
to light winds through midweek.

&&

.MARINE...
Expecting gentle to light westerly breezes across the Keys area
today. Light and variable winds overnight will turn northeast to
east and increase slightly. A trough will move across the eastern
United States on Thursday and help to strengthen the pressure
gradient around the Atlantic high pressure. This will result in
freshening breezes on Friday night through Sunday night. A small
craft advisory is likely late Friday through Sunday night.

&&

.AVIATION...
VFR conditions through the period with mostly clear skies. Expect
west winds 8-10 knots today with some gusts around 15 knots. Winds
will diminish to 3-7 knots after sunset.

&&

.CLIMATE...
On this date in Keys Weather History. April 25, 1948. 2.21 inches
of rain fell at the Key West Airport setting the daily record for
rainfall. Rainfall records for Key West date back to 1871.
