Discussion
03z wpc surface analysis paints the stationary frontal boundary that
has been pestering the region yesterday well to the south of our cwa
as a cold front, across the fl keys and southern bahamas. A
secondary frontal boundary located a pinch to the south of lake
okeechobee will continue to creep down across the region today
into tonight, bringing widespread stratiform rain and embedded
showers across the area. Convective activity is not expected as
lapse rates look relatively stable at around 5.5 c km or less
across south florida. The 20 00z mfl sounding remained fairly
moist with a pw of 1.63 inches, which is well above the 90th
percentile for this date. Essentially, it will be another soggy
day (not to the degree as yesterday), though it is expected to
clear from west to east throughout the course of the day. By
tonight, 15-30% pops will exist across the east coast, 25-40% pops
in the atlantic waters, and less than 10% pops elsewhere.

Temperature wise, highs for today will reach the mid to upper 70s
across the cwa, with the SW area hovering around 80. Tonight into
Thursday morning low temps are forecast to drop into the mid 50s
across the lake region, upper 50s across the west coast and central
interior, with low to mid 60s across the east coast.

For Thursday, a much drier pattern is in a store as zonal flow aloft
takes precedence and high pressure swiftly moves in across the
peninsula once an additional cold front clears the area (which looks
to be around Thursday morning to afternoon timeframe). A slight
chance of rain will prevail across the east coast metro and atlantic
waters before pushing completely offshore by the afternoon hours.

Friday into the end of the weekend, expect mostly clear, dry, and
seasonable weather due to high pressure. Highs this weekend will be
in the 70s to lower 80s, with lows in the 50s to lower 60s, except
40s west of lake okeechobee especially Thursday night and Friday
night.

By the beginning of next week, scattered showers may return to
the area as E SE flow returns and model guidance is hinting at
another longwave trough pattern closing in across the state. We
will continue to monitor this as the week progresses.

Marine
Winds will periodically shift between the northeasterly and
northerly directions at 10-15 kt throughout the day today. Winds
will then be back to more of a northerly direction late this week
with speeds increasing to breezy conditions.

Atlantic seas of 5 to 7 feet, with occasional 8 to 9 feet in the
gulf stream, will keep hazardous boating conditions around through
late tomorrow morning to afternoon. Seas will then remain at 4 to
6 feet through Friday before fading to 4 feet or less by
Saturday. The gulf seas will remain below 4 feet through the
remainder of the week. Therefore, an SCA will remain in effect for
all atlantic waters through this evening with an SCA in effect
for the northern atlantic waters until noon Thursday.

Aviation
Sub-vfr conditions linger with some brief bouts of ifr lifr
possible if a shower directly impacts a terminal overnight.

Conditions should continue to improve through the period as the
rain and cloud cover diminish. Some patches of br possible into
the morning with gradual improvement toVFR expected by midday.

Variable gustiness can be expected with convection and the east
coast terminals may see some directional variability overnight.

Beach forecast
The high risk of rip currents will remain in place for the atlantic
beaches through this evening due to the northeast wind flow. The
threat of rip currents will then slowly diminsh through late this
week as the wind flow backs to more of a northerly direction.

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.
