Discussion
Short term (today through Friday): the local weather pattern
continues to be dominated by subtropical high pressure at all
levels, most notably at the mid-levels where a 5950 meter center at
500 mb currently over north florida remains in place through today
and a low level ridge axis across central florida keeping an E se
wind flow in place. Relatively minor, but notable, day-to-day
differences in precipitation coverage location will depend largely
on embedded small-scale features in the prevailing E SE flow which
are discussed below.

Today: slightly drier air seen in last evening's 00z sounding from
nassau, as well as in GOES total precipitable water (tpw) data, will
move over south florida and lead to only isolated, small showers
early this morning. Some increase in showers (and possibly a
thunderstorm) is expected shortly after sunrise especially in the
palm beaches where deeper moisture resides. As has been the case the
past few days, showers and thunderstorms will then develop during
the late morning midday hours and increase in coverage from inland
palm beach county and the lake okeechobee area westward to collier
county and the gulf coast as the afternoon progresses and the gulf
seabreeze pushes inland and further focuses convective development.

Strong wind gusts, frequent lightning, and torrential rainfall can
be expected with the most vigorous convection over the western half
of south florida this afternoon into the early evening hours.

Higher 1000-850 mb thicknesses over the interior and western areas
today will translate to another day with highs in the mid 90s over
the interior and even close to the gulf coast, possibly reaching the
upper 90s in a few spots in eastern collier county. East coast metro
areas should hit the lower 90s except near 90 at the beaches. Heat
index values will have to be watched closely over the interior,
especially eastern collier county, where they could flirt with
advisory levels (108f for at least 2 hours).

Tonight and Thursday: a small mid-level trough currently north of
the western bahamas will move over south florida late tonight and
early Thursday, enhancing coverage of showers and thunderstorms over
the east coast metro areas and possibly cause this afternoon's
interior gulf coast convection to linger well into the night. As the
trough moves west across the peninsula on Thursday, convection
should be further enhanced over the interior and gulf coast Thursday
afternoon and evening. Once again, strong wind gusts, frequent
lightning, and torrential rainfall can be expected with the most
vigorous convection over the western half of south florida. Little
change in temperatures, with lows ranging from the mid 70s interior
to lower 80s east coast, and highs up in the 90s all areas. Heat
index values will once again approach advisory levels over the
everglades and big cypress preserve.

Thursday night and Friday: the center of the 500 mb high shifts to
the eastern u.S. And western atlantic. Drier air is depicted by the
gfs to move over the region late Thursday night and Friday, however
this could be countered by the influence of the northern end of a
weak tropical wave currently near puerto rico which may come close
enough to south florida on Friday. The end result is expected to be
a slight decrease in the coverage of showers thunderstorms favoring
the east coast in the night, morning and midday time frames and
interior gulf coast in the afternoon, but not appreciably so. Little
change in temperatures from today and Thursday.

Long term (this weekend into early next week): the deep SE wind flow
continues around the south side of the large mid-level high over the
eastern u.S. On Saturday and Sunday, with not much change in the
precipitation timing and coverage from the previous days. Models
have been consistent in showing a change in the large scale weather
pattern by Monday as the western atlantic subtropical ridge breaks
down in response to a large mid-level trough is depicted to sweep
into the eastern u.S., and a strong high pressure builds over the
intermountain west. At the same time, a tropical wave currently over
the central tropical atlantic near 50w may get close enough to south
florida to influence our weather. The GFS is faster is showing the
possible effects of the wave on Monday, while the ECMWF is slower
and farther east. For now will not increase pops as much as some
of the model guidance is indicating as we're still 5-6 days out,
but if trends continue then rain chances could increase further early
next week.

Marine
The main threat continues to be periods of showers and thunderstorms,
more numerous over the gulf of mexico waters each afternoon and
evening, but also increasing over the atlantic waters tonight and
early Thursday. This same general pattern of timing of showers and
thunderstorms will persist through the weekend. Otherwise, winds
generally E SE 10 knots, with periods of near 15 knots during the
night and early morning over the atlantic. Seas generally 3 feet
or less, except higher in and near showers and storms.

Beach forecast
A slight risk of rip currents will continue into the upcoming
weekend at the atlantic beaches with the continued light E se
wind.

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.
