Discussion
Short term (tonight-Tuesday)... A deep trough low complex is
migrating across the SE states, with an associated cold front
moving into the northwest corner of the gulf. This front should
move rather quickly and approach the state late Monday.

Meanwhile, the remnants of a frontal boundary remain lingering
over the central portions of the florida peninsula, while a sfc
high pressure system to the NE of florida continues to migrate
eastward. This is resulting in an overall synoptic scenario
conducive to flow veering to the south, and gradual moisture
advection into south florida. 12z mfl sounding data depicts a
very moist air mass with pwats of 2 inches.

Therefore, expect current active pattern to continue through the
short term with mainly scattered to numerous showers at times and
a few to scattered thunderstorms each day. Highest chances of
rain and thunderstorms are still expected Monday and Tuesday
afternoon. And although model solutions place the bulls-eye for
strongest convection over palm beach county and around lake
okeechobee (especially Tuesday), the miami atlantic metro areas
can also experience increasing shower and thunderstorm activity as
the overall flow veers to the SW ahead of the aforementioned
approaching cold front.

Also, latest model solutions suggest enhanced dynamic and thermodynamic
parameters on Tuesday, including CAPE of over 3k, cooler temps
aloft, and increasing instability, which may favor stronger
storms and or potential for some cells to become severe. The
greatest threats associated with any of the strongest storms will
be cloud to ground lightning, brief gusty winds, and locally heavy
downpours. Right now expecting any flood issues to remain local
and mostly advisory-level.

Long term (Tuesday night-Saturday)... Models keep pushing the
aforementioned trough low complex out into the tennessee valley,
with the associated sfc front moving past south florida by early
Wednesday. A much drier air mass will then filter into the area
behind the fropa, bringing stable conditions and overall benign
weather.

Long range model solutions continue to show a couple of energy
impulses quickly evolving over the us and pushing cold fronts into
florida Thursday through Saturday. However, timing and potential
impacts of these systems remain uncertain as there is still plenty
of time for significant model adjustments. Therefore, the forecast
will remain conservative regarding pops wx for this time frame
and wait for upcoming guidance before making any significant
changes.

Marine
Moderate to fresh southeast winds continue over the coastal waters
tonight, but expected to remain below advisory levels. However,
small craft should exercise caution through Tuesday, mainly over
the open atlantic waters, due to periods of winds of 15 to 20
knots and seas near 6 feet. Scattered thunderstorms will also
pose a hazard to mariners in all the local waters, bringing
locally higher winds and waves through Tuesday night. As a front
approaches, winds will veer around to southeast later today,
southwest by Tuesday, and then around to northwest Tuesday night
following its passage.

Beach forecast
A high risk of rip currents will continue through Monday at the
palm beaches due to persistent moderate southeasterly winds, with
a moderate risk at the rest of the atlantic beaches.

Aviation
Scattered showers and thunderstorms across south florida this
afternoon will create brief times of subVFR conditions. Easterly
flow will start to veer more to the southeast today. At kapf, a
gulf sea breeze will develop this afternoon. Winds will be between
10 and 15 knots, however, they could gust higher in showers and
thunderstorms.

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.
