Area Forecast Discussion
National Weather Service Melbourne FL
915 PM EST Wed Dec 28 2016

.DISCUSSION...

Quiet WX pattern overhead as a weak H100-H70 anticyclone centered
over the central peninsula maintains a weak pgrad acrs the region.
Evng RAOBs map the anticyclone quite well with wrly flow over the
panhandle...erly flow over the south peninsula/Keys, and vrbl winds
blo 10KTS over the central peninsula. Airmass is not overly moist
with PWats in the 1.00"-1.25" range, though sfc obs measuring
unseasonably high dewpoints in the M/U60s.

The weak pgrad will allow winds to become light and variable
overnight. Combined with minimal sky cover, anticipate strong
radiational cooling conditions. This will set the stage for fog
formation in the predawn hrs. Sat imagery does show sea fog pushing
onshore the Nature Coast, but the sea fog that plagued coastal
Volusia has shown no sign of rdvlpg as of mid evng.

Patchy radiational fog anticipated aft midnight. Light wrly flow
expected to dlvp in the predawn as a short wave over the MS Valley
works its way east and drags a stalled front from the Deep South
into the FL Panhandle. This will enhance the potential for advection
fog from the Nature Coast. Indeed, numerical guidance does indicate
potential for dense fog over the climatologically favored areas
along and north of the I-4 Corridor.

The aftn fcst package handles the current WX situation well...no
updates necessary this evng.

.MARINE...
Tranquil boating conds overnight as high pres draped over the FL
Peninsula maintains a weak pgrad acrs the lcl Atlc. Light E/NE
breeze bcmg light to gentle W/SW overnight as a frontal boundary
stalled over the Deep South begins to work its way into the FL
Panhandle region. Nearshore buoys measuring 2-3FT seas...mainly in a
9-10sec swell. No sig changes anticipated as the anticipated
windshift will be gradual with speeds remaining AOB 12KTS.

Conditions near shore will favorable Thu mrng, but small craft
operators venturing out to the Gulf Stream should know that the
return trip in the afternoon will be a choppier one as the sfc/bndry
lyr winds freshen out of the west to around 15 knots.
