Discussion
Today-tonight: a somewhat drier airmass has moved into south
florida today, and this has limited showers and thunderstorms. I
limited pops to 30 percent for the remainder of the afternoon for
the highest values anywhere in south florida, which is confined
mainly to interior and western areas. Pops generally range from 5
to 20 across east coast metro areas for the remainder of the
afternoon.

Wednesday-Thursday night: high pressure will gradually shift
eastward tomorrow and Thursday. As the high shifts eastward, a
strong upper-trough moves into the eastern u.S. This will lead to
light southeast to south wind flow. Deeper tropical moisture will
return to south fl. The light winds will allow for sea breeze
development on both coasts. Expect showers and storms to develop
along the sea breezes during the midday hours, becoming more
numerous over interior to interior-west areas during the
afternoons.

Friday-Monday: western atlantic high will build back into the
region returning easterly flow across S florida by late Friday or
Saturday, lasting through the weekend and into early next week.

Lingering moisture in the region will allow for showers and
thunderstorms streaming across the area through the end of the
extended period.

Marine
An upper trough will push the high pressure east veering winds s
to southeast mid week. The increase in moisture content will
enhance showers thunderstorms through the end of the week. This
weekend, high pressure builds back across the peninsula shifting
winds back to easterly flow. This will allow a few gusty winds
between 15 to 20 knots in the afternoon hrs. Seas will be up to 3
feet at times this weekend into early next week over portions of
the atlantic waters. Showers and thunderstorms are also possible
and capable of producing strong wind gusts, locally higher seas,
heavy rain, and lightning.

Beach forecast
A beach hazards statement is in effect for collier county beaches
through Thursday evening due to florida red tide, which may lead
to respiratory irritation.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. 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.
