Area Forecast Discussion
National Weather Service Melbourne FL
339 AM EST Tue Dec 20 2016

.DISCUSSION...

Today-Tonight...Low level northerly wind surge has been wedging down
the coast.  This surge represents the leading edge of a slow moving
cool front.  Canaveral profilers show the cooler air is shallow,
hence extensive low cloudiness has set in north of the boundary.  At
3 am, the low ceilings had reached down to south Brevard. The GFS
shows the boundary shifting into south Florida tonight.

Interestingly, the front combined with the late Monday boundary
generated convection over the interior, which kept it going well
into the early morning hours. This activity was just starting to
diminish near Lake Kissimmee. The atmosphere will be stable to the
north of the boundary today, but southern sections should heat up
to around 80, so some convection may regenerate with daytime
heating. Think that the greatest instability will be out over the
water, so do not anticipate isolated storms over land again. Any
precip north of the boundary will be light and close to the coast.
The models show the main amounts over the water and the HRRR model
even shows some thunderstorms over the Gulf Stream.

Early morning fog was dense around Okeechobee earlier, but
visibility seems to have improved, so not anticipating a dense fog
advisory there. Will have to watch for sea fog along the Volusia
county coast too, but so far visibility has been greater than 1
mile there.

The extensive cloud cover will hold max temps in the 70s except
lower 80s around Okeechobee.

Low temps tonight will be about 5-10 degrees cooler in the north but
just 2-3 degrees cooler in the south.  Slightly drier air filtering
in should preclude significant fog, though low ceilings are again
shown by MOS.

Wednesday...Diffuse low-level trough and associated moisture ribbon
over central Florida gets shunted south of Lake Okeechobee, allowing
slightly cooler and drier air to filter down across the region. Will
maintain a small PoP over the Treasure Coast in vicinity of higher
moisture and onshore flow, otherwise dry conditions expected.
Wednesday will be the "coolest" day of the week with max
temperatures ranging from near 70 across the far north to upper 70s
along SE coast, which is still near to slightly above normal for
late December.

Late Week...Surface high pressure building across the nations
midsection will push another front toward the region late Thursday
and early Friday morning. Nearly all mid/upper level support will be
separate from the surface feature, and yet another uneventful fropa
is expected. Low level flow is expected to rapidly veer to the
northeast and then east behind the front on Friday, so any chance
for precipitation will likely be confined to the coastal zone where
a few Atlantic showers push onshore. Post-frontal cooling remains
limited with onshore flow moderating temperatures on Friday.

Christmas Weekend...Surface high pressure will push out into the
western Atlantic, veering our winds further and allowing
temperatures to moderate over the holiday weekend. A weak coastal
trough will portend higher cloud cover over the Atlantic with a
small chance for light showers over the coastal zone. Post-frontal
cooling from the late week front will be short lived thanks to the
veering flow, and above normal temps are advertised.

&&

.AVIATION...Extensive stratus covering the terminals from KMLB-KISM
northward.  Ceilings have been oscillating a bit between IFR and
LIFR.  The low level flow looks strong enough to inhibit significant
fog, though visibility may also drop to LIFR along the coast mainly
at KDAB.  The ceilings will likely continue all day and again
tonight.  A brief period of MVFR should occur in the afternoon, but
after sunset the IFR-LIFR ceilings will gradually set back in.

&&

.MARINE...
Today-Tonight...A northerly wind surge working down the coast looks
moderate-fresh. The models sometimes underestimate these surges,
so have gone with the stronger looking GFS winds, which are still
just 20-21 knots. Seas are forecast to build to 5-7 feet in the
north, so will go with an advisory there, then will initiate one
down to Sebastian Inlet at 4 pm. These advisories should continue
into early Wed. morning. The northerly winds won't reach the
southern waters until tonight and they look to be 10-15 knots
at that time.

Wednesday/Thursday...Continued poor to hazardous boating conditions
as north wind surge gradually relaxes through the day. Seas will
remain elevated and up to 7 feet north offshore and north of
Sebastian Inlet. Gradient will relax further late Wednesday,
becoming 5-10 knots by early Thursday. Seas subside to 3-4 feet
nearshore, but remain 4-6 feet offshore.

Friday-Sunday...Secondary front will move across the waters early
Friday. A period of moderate to fresh onshore winds are expected
into the weekend as high pressure builds off the eastern seaboard
and veers the flow to out of the northeast on Friday and easterly by
Sat. Deteriorating conditions are expected and poor to hazardous
boating conditions will result.

&&

.CLIMATE...
Slow moving showers and storms that formed as a result of a late
day sea breeze collision over the interior produced locally heavy
rainfall late Monday night and early Tuesday morning. 1.49" of
rain fell at the Orlando International Airport in a 90-minute
period, with 1.13" falling before midnight, enough to set a new
record rainfall for the date (12/19). The old record of 1.11" was
last set in 1965.
