Vfr continues until around 12z when the onset of vcsh is
possible. Vcts is expected this afternoon with pops near 70
percent. Prob30 tsra groups remain in the tafs also for the
afternoon along with gusty winds. Light SW wind, variable at
times, will continue through around 12z, then wsw 10-12 kt by
late this morning and into the afternoon.

update...

showers and thunderstorms across the region that developed along
outflow boundaries and interactions with storms associated in
central florida and the lake okeechobee have begun to diminish
this evening. Only a few lingering showers with most of the
stronger activity out over the offshore atlantic waters. The
boundary will continue to move slowly southward overnight.

Moisture will increase with more widespread showers and
thunderstorms across the region tomorrow. No major changes to the
current forecast except for minor adjustments to account for
current observations.

aside from an hour or two of brief light shower potential this
evening, dry conditions should prevail overnight. Guidance
suggests early start to convection, so have placed vcsh starting
sunrise, becoming vcts in afternoon. With pops near 70 percent,
felt prob30 tsra was warranted during the afternoon along with
gusty winds. Risk of several hour period of restrictions is low,
so have left out any sub-vfr in tafs, but significant ones are
certainly likely Sunday afternoon. Light SW wind overnight become
10 kt by late morning Sunday.

rest of today and tonight: another hot day across south
florida with temperatures in the low to mid 90s across the area with
heat indices above 100 and much of the east coast above 105
degrees. Latest satellite imagery shows a definitive boundary across
central florida. Mostly clear skies across southern portions of the
region with drier air in place. However, as you move northward into
the lake okeechobee region a boundary, that has been stalled across
central florida, is beginning to sag southward down the peninsula.

The activity this afternoon and evening will be focused along the
boundary near lake okeechobee and northern portions of the region.

With the southwesterly flow in place a few showers over the gulf
waters may also affect the collier county coast this afternoon and
evening.

Temperatures tonight will be in the mid to upper 70s across south
florida with some coastal regions around 80 degrees tonight.

Rest of the weekend into next week: as the upper level trough cuts
off into an upper level low as it moves southward, it will push the
surface boundary and low level trough that has been draped across
central florida over south florida. Abundant moisture will move into
the area with model soundings showing high rh throughout the
atmosphere and precipitable water levels well above 2 inches.

Therefore, with the increased moisture content the chance for
showers and thunderstorms will also increase with more widespread
coverage to end the weekend continuing into next week. Model
soundings also show the 500mb temps cooling and freezing levels
lowering, increasing the chance for stronger storms, with some
isolated severe storms as well. The main threat throughout the
event will be locally heavy rainfall, with showers and stronger
embedded thunderstorms capable of producing gusty winds. The
threat for severe weather looks highest around the lake okeechobee
and palm beach region Monday afternoon. However, there will be
potential for strong storms across all of south florida each
afternoon.

Marine...

boundary across central florida continues to gradually move
southward down the peninsula. Seas will be 2 feet or less in both
in the atlantic. Southwesterly flow and fetch will increase seas
in the gulf to 3 to 5 feet in the offshore gulf by Monday.

Coverage of showers and thunderstorms will continue to increase as
the boundary moves southward. Sunday through the week coverage
will be widespread across all local south florida waters.Locally
higher winds and seas are possible near any thunderstorms.

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.
