High pressure ridge over the Northern/Central FL peninsula will
shift slowly SE overnight with NW flow aloft pushing in periods of
mainly thin high clouds to warrant Mostly Clear skies overnight.
Winds becoming near calm and will allow for temps to fall into the
lower/middle 40s inland and upper 40s/near 50 along the coast.
High pressure ridge slides further offshore into the Atlc on
Saturday with an increasing low level S-SW flow at the surface
which will lead to an increase in winds to 10-15G20-25 mph and
local SE sea breezes along the Atlc coast. The NW flow aloft will
continue to stream in periods of high clouds at times but will
still be mainly thin enough to warrant "Mostly Sunny" skies and
highs reaching into the upper 70s/near 80 inland, while SEly flow
along the coast during the afternoon will hold Atlc Coast
locations more in the lower 70s.
VFR with passing high clouds. S-SW winds increase to 10-13 knots
with gusts of 16-20 knots during the afternoon hours on Saturday.
Light/Variable winds becoming westerly 10-15 knots overnight as
high pressure ridge slides just south of the waters. Then shifting
to the S-SW on Saturday close to 15-20 knots as high pressure
pushes further offshore and next weather system approaches from
the NW and tightens the pressure gradient during the afternoon.
Rip Currents: Low Risk.
Despite a shift to S-SW flow on Saturday, still expect Critically
Low RH values falling into the 25-30% range just inland from the
coast and with sustained winds 10-15 mph with gusts to 20-25 mph
at times will need to monitor for possible Fire Weather Headlines.
