Numerous showers and scattered thunderstorms today...

Update
Forecast continues on track with elevated rain chances today given
a very moist airmass with 12z jax sounding showing pwat of 2.2
inches and mesoanalysis indicating a bit lower values in southeast
ga. Capping inversion has eroded a bit from yesterday suggesting
earlier start to showers and storms as well. A couple of shortwave
troughs are moving through fl, one that is over north central fl
that will be exiting off the coast by about noon and another one
over the fl panhandle that will be pushing into the forecast area
close to MAX heating time. There is a fairly large blanket of mid
level clouds over northeast fl and coastal ga that will hinder
daytime heating but these clouds will slowly disperse during the
day.

Latest model blends continue to support likely to categorical rain
chances today in the 60 to 80 percent range. For this update, have
just adjusted timing a bit based on hrrr guidance. A small area of
showers that are presently moving through the fl big bend may
intensify a bit and push toward the east coast by noon. Another more
significant area of showers and developing storms are moving through
the WRN fl panhandle and estimated to arrive in our WRN zones by
about noon to 1 pm. Based on sounding and radar vwps, storm motion
will be relatively fast today about 20-25 mph and sfc winds expected
out of the southwest at 10-15 mph with gusts to 20 mph and should
keep atlc coast sea breeze pinned at the coast. Modified sounding
yields SBCAPE of 3200 j kg. This environment will be favorable for
strong gusty winds of 40 to 50 mph and heavy rainfall in the
stronger storms. Thus, may see more reports of stronger wind gusts
in the storms today given the stronger movement of cells and
resulting outflow boundaries. MAX temps a bit warmer in ga near 90
deg given initially lesser cloud cover than northeast fl.

Aviation
Multilayered clouds in the area with areas of MVFR and patches of
rain sprinkles. Main shower and storm threats for all tafs
will be in a few hours when combination of daytime heating and
forcing aloft moves into the area. Have tempo groups for MVFR
cigs vsbys with gusty winds to 25 knots from 15-19z at gnv, about
16-20z for rest of the tafs. Activity should be ending by the 22z-
00z time frame and expectVFR conds for most of tonight. A few
showers could move in or near gnv toward 09-12z Thursday from the
gulf of mexico. Prevailing winds today from about 210 to 260 degrees
increasing to about 8 to 12 knots.

Marine
An offshore wind near 10 to 15 knots at this time will increase to
15 to 20 knots later today. Scec headline is in place for all waters
today. Winds will increase further to near 20 kt offshore tonight
and SCA already in effect. Current forecast looks on track with
little change. Expecting a round of showers and storms pushing off
the coast midday that may produce winds of 25-35 kt that should
be high concern for any smaller boater in the coastal waters today.

Rip currents: low risk in the offshore SW flow with surf breakers
in the 1-2 ft range.
