Discussion
Cold again tonight with patchy frost expected interior south...

tonight... High pressure ridge axis extending into central florida
from the gomex will sag south across south florida late tonight.

As mentioned in the am update, this is expected to produce cooler
temperatures and patchy frost across the southern CWA with light
westerly return flow north of the ridge slowing the nocturnal temp
fall there. MOS guidance actually came in cooler with some l30s ne
of the lake. Nudged these up by a couple degrees, however, am still
showing m30s across a large swath south and inland from the greater
melbourne palm bay area.

Tuesday... After another chilly start to the day, temperatures will
moderate more quickly than today as wsw-w boundary later flow kicks
in ahead of an approaching cold front, and becomes breezy by around
noon. The front will begin pushing across the northern CWA by late
afternoon, and likely bisect the central peninsula by early in the
evening (00z 7pm). Some increase in mid high clouds is expected
however, it shouldn't inhibit temps from warming into the l-m70s.

Tuesday night-Thursday... After dry frontal passage late on Tuesday,
winds veer NW as high pressure advances across the gulf coast. Each
night, temperatures dip into the low 40s, with some areas in
northwest volusia and north of lake okeechobee seeing mid to upper
30s. Highs Wednesday only reach the low to mid 60s, but climb to the
upper 60s Thursday across east central florida. Low moisture will
keep conditions dry and skies clear.

Friday-Monday... Forecast challenge for the extended range will be
exact timing of next trough that will bring a chance of showers for
late week. The ECMWF continues its trend of a deeper and slightly
slower shortwave trough with the bulk of the shower activity moving
through Friday night while the GFS has the timing about 12 hours
faster. For now will keep shower chances in both the Friday Friday
night periods before the short wave moves east of the state into
Saturday afternoon. High pressure should be near the peninsula in
the wake of the aforementioned trough by late Saturday into Sunday.

Generally mild temps are expected behind the next system with rising
500 mb heights across central florida. This will allow for high
temps in the 70s for Sunday and Monday and lows mainly in the 50s.

Aviation Vfr. Skc overnight with sct-bkn250 developing 12z-15z.

Winds from 250-260 will average around 16g25kt over most of the
aerodromes in the afternoon.

Marine Tonight-Tuesday... Moderate to gentle nw-n winds back to
w wsw starting just before sunrise north of the cape, then increase
and spread south ahead of the next cold front. Speeds forecast to
reach 20-25kt across most of the maor, however westerly wind
component should keep seas mainly in the 4-5ft range well offshore,
and 2-3ft near the coast. Think we can hold off on any SCA issuance
with this package for now, as 7ft seas would very likely start off
in period 3 (Tuesday night).

Tuesday night-Wednesday... Strong offshore flow will shift NW behind
passing front at 20 to 25 kts. Seas build to 7-9 ft offshore with
sca issuance likely. Seas remain elevated at 6-7 ft in the gulf
stream on Wednesday with winds gradually decreasing to 10-15 kts.

Thursday... Conditions continue to improve on Thursday, as winds
diminish to 10 kts, with seas subsiding to 2-4 ft.

Friday-Saturday... An increase in SW winds to 15-20 kt is expected
again on Friday ahead of the next front, which is likely to move
through either late in the day or overnight into early Saturday
morning. Post-frontal NW flow expected to commence this weekend.

Offshore component would keep highest seas well away from the coast.

Fire weather
Tuesday... Westerly low level winds will increase into the afternoon
and become breezy in some locations. High temps will warm into the
lower 70s in the afternoon allowing afternoon min rhs to drop to
between 35 to 40 percent.

Wednesday... Drier and cooler weather is expected with min rhs
dropping to around 30 percent across the NRN interior behind the
next dry front. NW winds expected up to 10-15 mph.

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.
