Discussion
Wind chill advisories issued for all of east central florida
for tonight...

Freezing temperatures look increasingly likely for lake and
volusia counties...

Freeze watch for tonight expanded southward...

current... Arctic cold front has pushed across the eastern florida
panhandle and is encroaching upon peninsular north florida early
this morning. To the south of the front, the high pressure ridge has
all but collapsed, with a light n-nw drainage flow in place across
ecfl. 3am temps were in the u40s-l50s north central and m50s south.

Today-tonight... Well-advertised arctic front will plow southward
across the peninsula this afternoon, moving south of lake okeechobee
early in the evening. Early afternoon highs will only reach l-m60s
across north lake volusia, and u60s-l70s from early to mid afternoon
to the south. Strong post-frontal CAA with increasing breezy NW nnw
winds through tonight, which will allow temps to plummet into the
30s for most areas, with widespread wcis in the 20s over all but the
immediate treasure coast (near the icw over the barrier islands) by
sunrise Thursday.

Latest temperature guidance indicates freezing temps remain most
likely across lake volusia counties, while near-freeing (33-34f)
temps reach well down into the interior. The freeze watch has
been expanded to include northern brevard osceola okeechobee
counties. Min temps in the 33-35f range also possible over rural
interior brevard indian river counties.

Thu-thu night... High pressure will center over the ARKLATEX region
as ridge axis noses east toward the carolina coast overnight
Thursday. Even with plentiful sunshine thu, temps will struggle to
peak around 50 across the far north cwa, to mid 50s central and
upper 50s near 60 far south. Synoptic pattern will favor a weak
drainage (nw) flow during the second half of Thu night, with
radiational cooling allowing min temps to drop into the 30s across
inland locales as well as to the coast north of the cape. Do not
anticipate the need for a freeze watch warning, however isolated,
wind-protected areas across lake and interior volusia counties may
briefly approach reach freezing around sunrise. With boundary
layer flow veering to an along-shore component across the
north central coastal plain and slight onshore component farther
south, min temps from the CAPE southward likely to remain in the
40s (perhaps even lower 50s along the martin coast).

Fri-sat... Shortwave ridge develops aloft Fri in advance of mid-
level disturbance which weakens as it approaches the central gulf
coast sat. Meanwhile, surface high builds slowly eastward across
lower gulf states and the fl panhandle. Light NE gradient flow
fri veers more easterly Sat and begins to tap region of higher
moisture upstream across the bahamas. Warming trend will commence
with maxs Fri jumping 8-10 degrees compared with thu, yet still
remaining below normal, especially along the coast from the cape
northward where trajectory over very cold shelf waters will limit
temps to the upper 50s. Elsewhere 60s. Not as cold Fri night, but
with a large temp gradient from NW interior (upper 30s) to se
coast (mid to upper 50s). MAX temps Sat returning closer to
normal, albeit still a few degrees below. Coolest along the coast
from the CAPE northward where temps will peak in the mid 60s.

Sun-tue... Weak disturbance aloft weakens further as it reaches se
coast. Next mid-latitude trough broadens as it extends from great
lakes region to SE us. This system likely to drag a weakening cold
front into the peninsula sometime between late Mon and late tue.

Front expected to slow as it approaches reaches CWA as trough axis
deamplifies. Small shower chance introduced to forecast Sun (se
cwa), continuing Mon (areawide), with period of considerable
cloudiness and scattered showers Tue when frontal boundary
most likely reaches slows across cwa. Temps continue to moderate
as winds acquire a more southerly component. Climo temps forecast
sun, then a few degrees above normal Mon before returning to a
little below normal Tue due to clouds showers and slight cold air
advection with N NE wind shift.

Aviation Vfr. Gusty NW winds from around 310 13g19kt veering to
330-340 8-12kt tonight.

Marine
Today-tonight... Nw-n winds 10-12kt increase and back slightly to nw
at near 20kt with initial post frontal surge. Winds veer again to
nnw as they increase further to 20-25kt tonight. Seas build to 6-8ft
near shore and 8-10ft offshore. A SCA will go into effect this
afternoon for the entire maor, with a cautionary statement in place
up until then.

Thu-thu night... Strong post-frontal northerly flow veers ne
overnight and lessens markedly as surface high noses east toward
the coast north of the area. Seas 5-7 ft nearshore and 8-10 ft
offshore Thu morning subside steadily through the
afternoon overnight as winds relax significantly. Seas 3-4 ft
nearshore and 4-6 ft offshore by daybreak fri.

Fri-sun... Surface high builds eastward, becoming centered over the
fl panhandle fri, then departing into the western atlantic over
the weekend, with ridge axis becoming established near 30 degrees
latitude. Extended period of favorable boating as winds become
light NE E fri, E 5-10 kt Sat and E 10 kt sun. Seas 3-4 ft fri,
except up to 5 ft over the gulf stream during the day, subsiding
further to 2 ft or less nearshore and up to 3 ft offshore over the
weekend.

Fire weather
Thu... Dewpoints have trended a litle lower than previous guidance,
which should result in min rh reaching 30-35 percent far inland,
mainly lake county, even with high temps only reaching near 50
degrees. N NE winds will be less than 10 mph.

Fri... While dewpoints begin to recover some, so do MAX temps.

Result should be one more afternoon of min rh near 35 percent over
far interior, mainly lake county. Light N NE winds 5 mph or less.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
