846 pm edt Sat apr 29 2017

A few spotty coastal showers this evening...

Update
Main update tonight is for modest upward nudging of pops for
isolated showers (15-20 percent) from melbourne to fort pierce as
a consequence of onshore moving convection. Looks to be wake
convergence wnw of grand bahama and great abaco. Hrrr hinted at
this but also suggests a bit more of a traditional rash breaking
into the overnight hours and retreating back primarily to the
adjacent coastal waters of the space and treasure coasts. Yet, an
isolated shower moving ashore cannot be ruled out so will oblige.

Winds should begin to decrease post-sunset to e-se at 5 to 10 mph
inland and 10 mph along the coast except 10-15 mph for treasure
coast. These less than fully relaxed maritime winds will keep min
temperatures in the l/m70s along the immediate coast while
limiting fog development and overnight pooling of smoke from
wildfires. Inland min tempeatures will generally be in the
u60s/l70s.

Sun... (from previous) surface high pressure remains stationed
over the western atlc with associated east-west oriented ridge
axis north of central fl. In fact, fairly deep high pressure
ridging across the region will keep a deep serly flow across ecfl.

Expect another breezy/gusty day with ese-se surface flow. Pwat
values are forecast to increase during the day to nearly 1.40-1.50
inches areawide. Have opted to keep a schc for light rain over
the treasure coast/interior early in the day with perhaps an
isolated rumble of thunder late in the day across lake county.

This due to the increase in moisture, slight cooling aloft, and
late day boundary collisions, though it remains entirely possible
that this scenario may occur west of lake county. Just want fellow
bike- fester's here to stay observant. QPF amounts are very low
and suspect most of the area will remain dry, but we will see an
uptick in cloud cover areawide.

The deep/strong serly flow with the added moisture/clouds may keep
our afternoon temperatures a few degrees below what we have
witnessed the past few days, though the additional moisture will
still make it feel sultry and people outside will need to stay
hydrated. Generally m80s along the coast and near 90 degrees/l90s
into the interior.

Aviation MostlyVFR thru remainder of this evening except for
tempo bkn025 kmlb-kvrb-kfpr due to vcsh thru at least 03z. Then,
spotty MVFR ceilings overnight bkn015-025 especially toward
09-12z.

Marine
Tonight-sun... East-west surface high pressure ridging remains
north of the local coastal waters thru the period. Necessary to
hoist SCA for offshore waters south of the volusia-brevard county
line and near shore from sebastian inlet thru at least early sun
evening. The pgrad sufficient to support near 20kt ese-se winds
here. Seas will also build to 6 ft across the proposed advisory
area. Cautionary statements necessary elsewhere except for
nearshore waters north of volusia-brevard county line, yet may
still include near shore volusia by Sunday morning or early
afternoon. Dominant wave periods will be generally choppy between
5-7 seconds.
