Area Forecast Discussion
National Weather Service Key West FL
458 AM EDT Fri Apr 28 2017

The Florida Keys continued to remain precipitation free overnight
and during the first hours of this Friday. Temperatures have been
all night at a steady 80 degrees at Key West and 81 at Marathon,
with dew points in the upper 70s at both airports. Winds were
from the southeast at near 10 mph.

A high pressure over the Atlantic will stretch across northern
Florida today and lift north and shift westward. As a consequence
of this repositioned of the high and an increase of the pressure
gradient between the high and the Keys, winds will be from the
east to southeast and increase tonight. Another thing that we can
adjudge to the high, is the lack of chances of precipitation and
summer-like conditions for this weekend. Max temperatures are
expected to be reaching the upper 80s during the next few days.
Dew points today will remain in the upper 70s and coming down to
the lower 70s on Saturday. As the high pressure sits in the mid
Atlantic, it will bring moisture from the Caribbean to near our
area late Sunday night into Monday as a trough in the upper levels
brings instability from Sunday night to Tuesday as well. On
Wednesday and Thursday, weather conditions should get quiet


Southeast winds this morning were gentle across the Florida Keys
coastal waters. These are expected to remain in the 10 to 15 knots
range today and increase tonight to 15 to 20 knots and near 20
knots for the Atlantic side waters. Therefore, a Small Craft
Advisory will likely be required starting tonight and possibly
extending to the rest of the waters on Saturday or Saturday night.


VFR conditions will prevail at the KEYW & KMTH terminals today
and tonight. East to southeast winds will be sustained between 10
to 15 knots through this afternoon, with gusts near 20 knots later
this evening and tonight.


On this date in 1873, the high temperature in Key West hit 90
degrees. This is a long-standing high temperature record for April
28th, since temperature records for the city date back to 1872.
