Update
Early evening radar data was showing vigorous thunderstorm
activity focused over interior portions of south florida, slowly
drifting south-southwestward. This is captured well by current
grids, which should continue through the rest of this evening.

Therefore, no significant changes are required for the evening
update.

Winds will become more northerly tonight and into Wednesday as a
cold front over northern florida reaches the area, along with a
very active weather pattern expected for Wednesday afternoon.

discussion...

short term (tonight-Thursday)... Model solutions depict an
amplifying mid upper lvl trough over the SE states, gradually
migrating eastward. An associated sfc cold front boundary is
pushing through the northern half of the florida peninsula,
bringing increasing chances of showers and a few thunderstorms
across south florida through Wednesday night, with better chances
over the eastern half of the area. 12z mfl sounding shows pwats
around 1.5 inches, while model soundings still show 1.5-2.0 inches
during the next day or so. Thus, shower activity will continue to
increase through Wednesday night, then a drying trend begins
Thursday morning.

The FROPA remains weak, which will not bring a significant change
in temperatures, with most places remaining near or at normals.

However, southern-most interior areas could reach upper 80s on thu
afternoon.

Long term (Thursday night-Monday)... Global models show the
aforementioned trough moving into the western atlantic during the
second half of the work week as the dissipating front clears the
peninsula on its way to the florida keys. High pressure quickly
builds in the wake of the FROPA with northerly winds gradually
shifting to a more ene flow by Thursday night into Friday.

Pressure gradients become tighter during the weekend with
possible periods of breezy winds across much of south florida.

Remnant moisture lingering over the area will be enough to fuel
some scattered showers and a few storms, mainly each afternoon
with daytime heating. Temps will remain around normal through
the extended forecast period.

Marine...

winds are shifting to more northerly flow ahead of an approaching cold
front moving across northern florida. The northerly northeasterly
flow will increase to around 20 knots by end of the work week.

Seas will be 2 to 5 feet before increasing later this week
especially in the atlantic waters.

Aviation...

a weak cold front is slowly approaching the area, helping to enhance
the chances for rain, and maybe a few thunderstorms. Chances increase
through the night, into tomorrow. Storm chances are on the low end,
so only vcsh in the tafs for now.VFR is the predominate condition
through the TAF period, with brief ifr under heavy showers possible.

There is a chance for lower CIGS to move into the area tonight, but
it is unclear how low they will be. For now, forecast sct020-025
with bkn030, but could be bkn015-025 at times.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

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.
