Discussion (today - Tuesday)
Strong mid to upper-level ridge over florida will build northward
over the next several days and extend across much of the eastern
2 3rds of the country by the weekend. This will bring hot and
humid conditions to most of the eastern u.S.

Models are in fairly good agreement depicting a deepening mid to
upper-level trough over the eastern half of the nation on Monday
and Tuesday, displacing the ridge to the south and east.

Closer to home, our weather will be dependent on the position of
the sub-tropical ridge. Our afternoon storms are more numerous
near the coast south of the ridge axis, and farther inland north
of the ridge axis. Since the low-level ridge axis is forecast to
meander over central florida through the weekend, expect the best
coverage of afternoon storms to be near the coast south of tampa
bay, and farther inland to the north.

As the upper-level ridge moves out in response to the deepening
trough on Monday and Tuesday, the surface ridge is likely to
retreat into the atlantic as well, allowing sea breezes to push
more quickly inland both days. This should keep highest rain
chances east of i-75 for the start of next week.

Aviation
Similar to yesterday, scattered to numerous showers and storms
will develop along afternoon sea breeze boundaries again. Expect
predominantlyVFR conditions with a good chance of some
intermittent MVFR ifr lifr conditions after 18z. No tempo groups
included at this time due to timing and location uncertainties.

Marine
Light winds and slight seas will continue through the weekend.

There will be some enhancement to the winds along the coast each
afternoon with the sea breeze. The only hazard will be the
possibility of evening thunderstorms moving off the coast each
day.

Fire weather
No fire weather concerns through the weekend.

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.
