Update
Showers have persisted, even enhanced slightly, over interior
south florida this evening, so have adjusted rain chances up some
for the next few hours. Thereafter, activity should mainly be
confined to the southern and eastern portions of the region. Aside
from pops, no changes to forecast warranted.

Prev discussion issued 730 pm edt Mon sep 25 2017

most of the convection this afternoon has remained in the interior
and south.VFR conditions will prevail through the period with vrb
to calm winds through Tuesday. Convection inland will be possible
tue afternoon as sea breezes advance and boundary collisions
occur. It is difficult to mention which sites will be affected at
this time, therefore no mention of vcsh on current tafs.

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.

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.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
