Update
Strong mid-evening convection which erupted along the lake wales
ridge from the sea breeze collision has sent sent a convectively
active outflow boundary back eastward across the kissimmee river
from south of lake kissimmee to west of lake okeechobee. Because
storms have redeveloped along the boundary, will need to leave in
shower storm chances across okeechobee and southern osceola cos.

With the last few bref scans showing cells becoming stationary,
will keep western sections of the treasure coast counties precip
free for now.

Aviation Vfr becoming clr blo 120 pretty much areawide by 04z.

Aforementioned convective redevelopment over the interior starting
around 01z has gotten to 40-50sm west of the vrb-sua corridor, but
is expected to slow weaken well west of those aerodromes.

Marine Local buoys show seas at around 1ft near the coast and 2ft
well offshore under light winds. Conditions across the local atlantic
will remain benign overnight and into late week.

Prev discussion issued 725 pm edt Wed jul 17 2019
thu-sat (previous)... Persistence based forecast will be continued
each day with the subtropical western atlc ridge remaining across
central fl. Inland areas will be favored for higher pcpn chcs due to
afternoon boundary collisions and weakly onshore component steering
level winds. A couple of weak upr disturbances moving across ga N fl
thu and into Fri wl partially erode influence of the local ridge to
the north of the local area, but not enough to significantly affect
pop from n-s attm. Expect highs in the l-m 90s and lows in the mid
70s. With 20-30 pop coastal co's and 35-45 pct inland.

Next week (previous)... Looking ahead for any changes to forecast
regime, which is typically dependent on surface ridge placement this
time of year, shows only subtle hints as weakening of the western
atlc ridge by the middle of next week. Positioning across central fl
early in the week will keep a coastal -vs- inland pop split with
deep moisture and the weak wind environment continuing to favor
inland areas for best chcs of daily measurable rains. A broader and
fuller latitude upper wave advertised to enter the SE states and n
gulf by Wed will help raise pop areawide toward the end of the
forecast period at midweek, and likely continuing toward the end of
the work week as well.

Aviation
A more active day is expected this afternoon into the late evening
with scattered showers and storms mainly focused across the interior
peninsula. Coastal sites will see brief vcsh through mid afternoon
then expect dry conditions once the sea breeze pushes inland. Latest
high resolution models and current visible satellite show increasing
instability over the fl peninsula, with showers and storms already
developing along the sea breeze. Impacts are likely this afternoon
at mco sfb ism lee as storms move slowly to the west-southwest
though storm motion along the sea breeze will be more variable. Have
refined the timing of the tempo groups and vcts for when storm
impacts are likely.

Marine
Tonight... Se winds to 10 knots this evening will become southerly
overnight. Seas 1-2 ft early will increase late to 2 ft near shore
to 2-3 ft well offshore.

Thu-sat... Favorable winds and seas with dominant surface ridge over
the marine area. Winds largely 8-13 kts or less with seas 1-3 ft.

Extended... Early next week shows continuation of favorable open
water conditions with s-se winds becoming onshore in the afternoon.

Seas 2-3 ft.

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.
