Discussion
Short term (tonight through Wednesday night)
light flow is expected through the short term, thus convection
will be dominated by sea-breeze activity. Moisture levels are not
all that high, so expect below climatological coverage of showers
and thunderstorms. Temperatures will remain near seasonal normals,
reaching upper 80s to around 90 degrees during the days, and 70s
for overnight minima.

Long term (Thursday through Sunday)
mid and upper level trough will deepen across the eastern conus
for the latter parts of the week, this will send a cold front into
northern florida, which may stall near or just north of the region
over the weekend. These features will allow deeper moisture to
spread northward from the caribbean and into south florida. Thus,
showers and thunderstorms are likely Thursday and Friday. For the
weekend, GFS now dries the area out a big, with moisture shunted
to the south, whereas ECMWF depicts south florida remaining in a
highly moist and unstable environment. Models also hint a weak low
pressure development between south florida and the bahamas along
the decaying frontal boundary, so will keep rain chances
relatively high over the weekend. Maxima may be somewhat limited
by rainfall during the period, but assuming some periods of solar
radiation, temperatures will remain around average for the end of
september.

Marine
Northeasterly swell from hurricane maria has been making its way
into south floridas atlantic waters. This is creating seas of up
to 8 feet in the gulf stream off palm beach county, where a small
craft advisory remains in effect.

Winds will not be a factor for the rest of the week. Shower and
thunderstorm coverage will increase late this week.

Aviation
Convective coverage is limited compared to previous days, mainly
along the sea breeze boundaries this afternoon. Convective
coverage will increase inland as the sea breezes advance and
boundary collisions occur. Activity should diminish this evening
with light winds expected.

Beach forecast
High surf advisory in effect for palm beach county coastline,
where some breakers, in association with swell from hurricane
maria, may reach 10 feet. This swell is also leading to a high
risk of rip currents on all atlantic beaches.

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.
