Update
Frost advisory for interior east central florida late tonight...

large cold surface high centered over the NE gomex eastern gulf
coast will continue to drift eastward overnight, cresting over
southern al ga and northern fl right around sunrise Tuesday.

Light n-nw drainage flow will slacken to light calm winds. Given
the forecast position of surface high and dearth of high level
cloudiness, conditions appear to be ideal for frost formation,
especially in wind-sheltered rural interior areas away from the
relative warmth of larger inland lakes.

Other than a couple tweaks to frost verbiage, no changes are needed
to the inherited forecast.

Aviation Vfr skc.

Marine Evening buoy data indicates slackening winds compared to
earlier today, 15-20kt and 5-6ft near shore. It's reasonable to
assume 20kt winds 7ft seas are occurring farther offshore with seas
even a bit higher in the gulf stream. Since winds are in the process
of diminishing with seas taking several hours longer to subside, we
should be able to allow the SCA to change over to "sca for seas" per
the current forecast.

Prev discussion issued 356 pm est Tue dec 11 2018
Wednesday... Dry airmass in place and high pressure building into the
region from the west will produce light winds and clear skies into
tonight. This will lead to another cold night with temperatures in
the 50s late this afternoon dropping rapidly into the 40s after
sunset and through the evening hours. For lows, leaned toward the
cooler met guidance, and even shaved a degree or two off these
values as MOS can be a tad high for nights like tonight when
favorable radiational cooling conditions are in place. This keeps
min temps ranging from the mid to upper 30s over much of the area
late tonight, with frost formation expected. Areas of frost should
develop away from the coast, especially over more rural low lying
interior locations west of i-95. While for urbanized inland spots,
and places along the coast, frost will be more patchy. Have
therefore issued a frost advisory for the interior counties and
inland volusia county where greater coverage of frost is expected.

After a chilly start to Wednesday, temperatures should warm up
into the mid to upper 60s across much of the area, expect around
70 degrees along the treasure coast. These values will still be
lower than normal for this time of year, but it will be warmer
than the past couple days. A relatively light onshore flow will
begin to modify the dry airmass in place, but rain chances will
remain out of the forecast with just a slight increase in cloud
cover across areas southeast of orlando into the afternoon.

Wednesday night Thursday (prev)... A weak coastal trough is forecast
to develop overnight Wed night along the fl straits with feature
responsible for some lower cloudiness and increasing coastal marine
shower chances into thu. Moisture is showing a marked increase
areawide during Thu as an upstream disturbance begins to approach
the region, coupled with return flow around departing high pressure.

Will keep a sct chance of showers areawide to account for this
activity and lower range measured amounts possible.

Extended (previous)... Next significant system approaches the region
late week as a strong shortwave moving across the great plains is
shown closing off as developing low pressure over the lower ms
valley fri, and transits toward the SE states at presently varying
speeds into Fri night. Given model spread in onset of impact ranging
from Fri to Fri night, storms will be carried for the local area
during at least two periods Fri fri night with an appreciable warm
sector and strong wind fields accompanying approach of this rather
potent feature. It is anticipated consensus in guidance later this
week will allow for better refinements on expected timing and
impacts from expected storms. Cooler and dryer conditions will
follow passage of the system this weekend and into early next
week.

Aviation Scattered stratocu deck clearing out north of kmlb
this afternoon leading toVFR conditions this evening and
overnight. Breezy NW winds decreasing after sunset, becoming
light and variable.

Marine
Tonight-wed... Poor to hazardous boating conditions will continue
through at least Wednesday morning. North-northwest winds up to
15-20 knots will decrease to 10-15 knots into tonight, but seas
will remain elevated over the gulf stream waters. Have therefore
kept SCA continuing for offshore waters and nearshore, south of
sebastian inlet through this evening, transitioning to a SCA for
hazardous seas late in the evening and continuing through early
Wednesday. Nearshore north of sebastian inlet, small craft should
continue to exercise caution for seas up to 6 feet.

Thu... Se winds will increase to 15-20 knots offshore by afternoon
with scec conditions developing across all the waters into thu
evening.

Fri-fri night... Se S winds Friday will increase to near 20 knots
with advisory conditions developing across the waters as a cold
front approaches from the west. Expect a high coverage of showers
and scattered storms to precede the frontal passage with strong
storms possible.

Sat-sun... The front will push offshore into Saturday afternoon with
surface winds veering the west behind the front to 15-20 knots
offshore. Seas to 6-7 ft offshore Saturday will decrease to 4 to 6
ft offshore by Sunday afternoon.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
