Discussion
Temperatures will gradually warm up through this weekend... .

Current... Cold surface high covers the deep south early this morning
with the ridge axis extending along the gulf coast from texas to
south ga north fl. Temps have fallen below freezing across sheltered
areas NW of i-4, with some u20s noted over north lake and NW volusia
counties. Temps transition to u30s-l40s farther south and east. Skc
save for some thin high clouds stream overhead. The unusually cold
shelf water temps really eroded late afternoon early evening attempt
at onshore advection of marine clouds, and the western edge remains
well offshore at this time. The timing and placement of the freeze
warning north and frost advisory south through 8 am look fine.

Today-tonight... Surface ridge center will drift ese from the eastern
gulf coast across north florida and into the atlantic over the next
h24. As this occurs an amplified positive tilt short wave trough
will drift eastward from texas to la ms-nw gomex. As surface winds
continue to veer to ne-ene and slacken, the flow aloft will back to
sw with increasing h50-h20 in high level rh values. This should
cause some increase in high clouds, while modest onshore advection
of marine sc occurs, mainly over the treasure coast counties. Maxes
will rise into the 60s areawide save for parts of immediate coastal
volusia county (u50s) as light onshore flow combines with shelf water
temps in the l50s to hold readings down some there.

While onshore flow in the afternoon modifies dew points to where
mins won't be as cold tonight, expect widespread 40s for mins, with
some u30s over rural north lake NW volusia as under light to calm
winds.

Saturday-Sunday... Surface high pressure is forecast to shift over
the peninsula and into the western atlantic, allowing winds, though
light, to gradually veer to the E SE with time. Considerable mid and
upper level clouds are expected on Saturday out ahead of short wave
energy transiting the deep south. Guidance tries to produce some
light precip as the short wave passes overhead, but a glance at
forecast soundings indicates considerable dry air lingering just
above the surface. Will continue to undercut MOS guidance and keep
most areas precip-free this weekend. Steady modification of the
local airmass during the period will lead to a slow climb in
temperatures, but it should be noted that the abnormally cool
atlantic shelf waters will keep highs down along the coast,
especially north of sebastian inlet.

Monday-Thursday... A longwave trough over the central CONUS is
forecast to lift toward new england early next week, largely
abandoning its surface front over the deep south. Warm southerly
flow out ahead of the front will bring above normal temperatures
areawide, with 80 possible Monday afternoon across the interior. The
front will sag down the peninsula Tuesday with little more than an
increase in cloud cover and a shower or two. Temps will trend closer
to normal by mid week as winds shift out of the N NE behind the
boundary. By late in the week, uncertainty builds with the gfs
indicating weak low pressure transiting the gulf and the ecmwf
maintaining drier E NE flow. Sided with the ECMWF and its ensemble
members, significantly undercutting MOS guidance on Thursday.

Aviation Vfr. Could see some brief CIGS bkn030-035 from kvrb-ksua
today, however expect these to scatter out to a large extent given
how cold the ocean temps remain.

Marine
Today-tonight... Nwps seems to be underdoing the rate of decay in
seas once again as 3-4ft seas near shore and 5-6ft offshore prior to
sunrise will subside to 3-5ft today and 2-4ft tonight as the surface
high pressure ridge drifts across north fl. Winds will slacken to
less than 10kt out of the ne-e.

Sat-sun... High pressure shifts over the peninsula and into the
western atlantic this weekend. Winds shift from the NE on Saturday
to the E SE Sunday while remaining 10-15 knots. Seas 2-3 feet over
the shelf waters, 3-4 feet offshore and in the gulf stream.

Mon-tue... Winds veer to the south on Monday ahead of a weakening
cold front which will sag down the waters on Tuesday. Winds expected
to remain at or below 15 knots. Seas 2 to 4 feet.

Fire weather
This afternoon... Expect min rh values to drop below 20-30 percent
from the i-4 corridor to the ocala forest and 30-35 percent a bit
farther S E from around the saint johns river to lake kissimmee.

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. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
