Update
Generally dry conditions continue to reign over south florida,
though some pockets of moisture have allowed atlantic showers to
develop and push ashore. Raised pops to include mention of showers
through the morning hours. This afternoon will be generally dry
for the east coast metro with the convective focus over inland
south florida and metro southwest florida later in the day.

Showers should be the predominant convection though some could
grow enough to produce some lightning strikes. Updated zones have
been sent to show this change. Have a wonderful day!

morning showers that have developed over the atlantic could affect
the east coast terminals over the coming hours. They should
diminish and transition westward with a focus over inland south
florida and southwest florida later today. Currently, apf has
showers mentioned but thunderstorms cannot be ruled out and could
be added in the coming issuances. Southeasterly to easterly flow
should prevail with variable gustiness around convection.

discussion...

high pressure looks to continue to dominate the weather pattern
through the weekend. A
a bermuda high is forecast to remain in place through Sunday
night. Along with this surface high, there is a high centered
over the region at 500mb. Models are indicating that both the
surface and 500mb highs will begin to weaken on Sunday.

However, even with the highs in place, enough moisture, with
pwats forecast to rise to just below 2 inches over the western
interior today, and diurnal heating will occur to allow for a
chance of mainly afternoon convection for the next several
afternoons. With the east to southeast flow, the areas with the
best chances will be the gulf coast, western interior and western
lake regions.

Taking a look at 500mb temperatures, the GFS has -5c to -4c and
the ECMWF is very similar, possibly even slightly warmer at times.

Given this, will keep most of the activity for today as a slight
chance to a chance of showers, with a slight chance
thunderstorms for much of the area west of the southeast metro
area. Beyond today, went ahead and kept scattered showers and
thunderstorms in the interior, but that may also end up being
limited to a slight chance of thunderstorms, if the models
continue to show warm temperatures at 500mb.

For the beginning of the week, both the ECMWF and the GFS have a
500mb trough digging across the eastern us. They also have the
bermuda high retreating to the east, ahead of a cold front that
will move into the north florida Sunday night. This front is not
progged to make it too much further then north central florida.

It will mainly effect additional moisture and convective activity
south of it. This has caused pops to begin to rise Monday and
Tuesday, as the front stalls. Models are showing the front will
dissipate during the middle of the week, as high pressure builds
in from the north, slides east, and takes residence as a
replacement bermuda high by the end of the week. As it does this,
it will keep showers and thunderstorms in the forecast for mainly
the afternoon and early evening hours through the end of next
week.

Marine...

a bermuda high will keep seas smooth to slight through the
weekend. The wind is forecast to continue to be east to southeast
around 10 to 15 kts through the weekend. While the chances of
showers and thunderstorms are lower this weekend, they are still
possible across the coastal waters. The chance of convective
activity will pick up again next week.

With the forecast wind, there is a moderate to high risk of rip
currents for the atlantic beaches. Given yesterdays observations
of strong rip currents at the east coast beaches, have kept the
high risk of rip statement out through the day today. The wind is
forecast to weaken after today, which should allow for the risk
to drop down to moderate after today.

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.
