Area Forecast Discussion
National Weather Service Tampa Bay Ruskin FL
907 PM EST Sun Dec 20 2020
.DISCUSSION...
Convection ahead of the front has shifted mainly south of I-4 at
this point with scattered showers lingering behind the main line.
This will continue to gradually shift southward through the
overnight hours with the front pushing through. Clearing on Monday
as high pressure builds into the area with some cooler air also
filtering in. Current forecast is on track with this, but have
updated the POPs for this evening. Update is already out.
&&
.AVIATION...
Thunderstorms will still be possible for another hour or so at
KLAL, otherwise just a few lingering showers possible through the
overnight hours across the northern terminals. Across the southern
terminals, rain is moving into KPGD now and will continue for the
next few hours spreading southward. Some MVFR conditions through
the overnight hours and then clearing out behind the front as
winds turn NW.
&&
.MARINE...
Winds and seas briefly increasing behind the front with SCA
conditions through the overnight hours across the northern and
central offshore waters. As high pressure builds in Monday, the
gradient relaxes and winds and seas will subside below advisory
levels. High pressure will then remain in place across the area
through Wednesday, with the next front later Thursday.
