Area Forecast Discussion
National Weather Service Key West FL
1038 PM EDT Sun Oct 20 2019

Currently - A surface ridge across Cuba is gradually pivoting
northwards towards the Keys. Consequently, surface winds have
weakened and swung around to southeast to south. This evenings
sounding indicated a good amount of dry layers and some very low
level inhibition. The above factors have contributed to very
little shower activity across the forecast area. Dew points remain
in the upper 70s with temperatures slowly falling through the
lower 80s.

Short Term Update - Winds will remain light out of the southeast
to south overnight due to the proximity of the surface ridge. The
weak flow and dry layers aloft will keep rain chances slight at
best. With dew points remaining in the upper 70s, there is not
much room for temperatures to fall. Expect overnight lows to
bottom out near 80. A few protected locations could drill down
into the upper 70s with the aid of radiational cooling under
mostly clear skies.


A ridge dragging northward through Keys waters will result in
continued light southeast to south breezes across Keys waters
through the overnight period. Have only removed first period
transitional wind wording in the evening marine update.


VFR conditions will prevail throughout the forecast period at
both terminals. Expect light predominantly southeast winds with
continued SKC to FEW skies.
