Discussion
Turning much colder into tonight with lows in the 40s and 50s...

tonight-Friday... With cold front now offshore, colder and much
drier air will continue to filter down into the region in the low
level N NW flow. It will turn much colder into tonight, with
temperatures falling into the 40s over much of the region, except
remaining in the 50s toward the coast, south of the cape. Drier
air will continue to erode the low cloud deck moving through the
area, with skies becoming clear overnight. Cooler and dry
conditions then expected for Friday, with highs in the mid to
upper 60s, except low 70s along the treasure coast. Skies will be
sunny with northerly winds around 5 to 10 mph.

Weekend... High pressure over the central gulf coast will slide
eastward late Friday into Saturday. Initial north flow will veer
northeast through this transition, becoming onshore by Sunday. Dry
airmass remains in place, with pwats hovering near half an inch
through the weekend. This limited moisture will keep pops near zero,
with only a slight chance of showers for coastal volusia late Sunday
afternoon. Cooler air behind the frontal passage dips temperatures
sat morn into the low 40s for the northern interior, mid 40s west of
the st johns river and low 50s along the coast and urban areas.

Afternoon highs return to near to slightly below normal in the low
to mid 70s on sat, with the warming trend persisting into Sunday,
with lows ranging from low to upper 50s, highs Sunday sneaking to
near 80 degrees.

Monday-Tuesday... A longwave trough across the eastern states and
surface high pressure near the tn valley will keep n-ne low level
flow across east central fl for early next week. The airmass will
be relatively dry with a low shower chance mainly across south
coastal sections. Highs are expected in the mid 70s across volusia
county and NRN lake counties to the upper 70s around 80 across
the remainder of the area. Lows in the 50s interior to lower 60s
coast.

Wed-thanksgiving day... Low level flow will veer to onshore into mid
week with the GFS and ECMWF indicating a significant mid level wave
shortwave poised across the WRN gulf with low pressure development
ahead of it by thanksgiving day. Model forecasts indicate increased
shower convective chances as this system approaches fl just beyond
the day 7 fcst period. At this point will keep onshore moving shower
chances for the treasure coast Wednesday and 20 30 percent shower
chances across eastern portions of the forecast area on thanksgiving
day. Temps will remain near normal for late november. Lows in the
mid-upr 50s interior to lower 60s near the east coast. High temps in
the mid 70s north to upper 70s near 80 across the central south.

Aviation Low cloud deck producing MVFR conditions will continue
to shift southeast, with much of the area likely experiencing bkn-
ovc MVFR CIGS through early this evening. Models then have drier
air filtering in behind the front and quickly eroding these low
level clouds, with skies becoming clear andVFR conditions
returning from north to south this evening into the overnight.VFR
conditions will persist through Friday as skies remain sunny, with
northerly winds around 5-10 knots.

Marine
Tonight-Friday... Poor to hazardous boating conditions will persist
behind the cold front tonight through Friday. Northerly winds up
to 15-20 knots will build seas up to 7 feet over the gulf stream.

A small craft advisory will continue offshore and nearshore, south
of sebastian inlet for these hazardous conditions. Small craft
should exercise caution across the nearshore waters of volusia and
brevard counties for seas up to 6 feet.

Weekend... SCA conditions offshore will diminish as high pressure
builds across the south. Initially, seas of 4-5 feet nearshore
building to 6 feet offshore early Saturday will subside to 3-4 feet
near and 4-5 feet offshore by Sunday afternoon. North winds of 10-15
knots gradually veer onshore as the sfc high moves closer to the
atlantic coast. Low moisture will keep rain chances near zero
through the period.

Mon-tue... N NE winds are expected up to 10-15 knots at times with
seas 3-4 ft near shore and 4-5 ft offshore. Seas may be higher in
the gulf stream if the pressure gradient tightens further on the
back side of a low pushing offshore from the southeast atlantic
coast by early next week.

Fire weather
Fri... Colder and drier air will build into the region tonight
through tomorrow. Min rh values in the mid to upper 30s are
expected across the interior, mainly from the orlando area
westward. Winds will be out of the north around 10 mph.

Sat-sun... Flow veers onshore and gradually modifies the cooler and
drier airmass in place. Min rh values may still fall into the low
40s across the far interior Saturday, otherwise rh values remain
above critical levels.

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.
