Cold front moving through extreme SE florida at the beginning of
this forecast period will be well offshore by 06z. Layer of
bkn ovc clouds around 3,000 ft will linger through much of the
forecast period at the east coast sites, although there will be
periods of ceilings lifting to around 5,000 ft. Kapf naples will
see clearing skies after 08z. Any precipitation will remain over
the atlantic waters. Winds NW 10-15 knots with a few gusts to near
20 knots, becoming N after 14z.

Drier, cooler air to end the week behind a cold front...

discussion...

the convection ahead of a cold front moving across south florida
has pushed into the atlantic. Some isolated convection does remain
around the coast, which some high resolution guidance keeps
suggesting that we may see additional activity flourish as the
cold front approaches from the west and the convection shifts over
the warmer gulf stream waters.

Overnight, drier and cooler air will overspread the southern
peninsula of florida. Aloft, a low to mid level deck of cloud
cover could persist which may linger into the day on Friday. This
will help temperatures cool into the upper 40s lower 50s west of
lake okeechobee and see temperatures over the east coast metro
dive into the lower to mid 60s tonight. On Friday, temperatures
will struggle to reach into the 70s over much of the area.

As surface high pressure builds back in over the gulf of mexico
Friday, it will help shift the winds out of the north which will
lead to another chilly overnight Friday night into Saturday
morning. As the weekend progresses, the surface high pressure will
build in over the eastern third of the nation which will allow an
eventual return to northeasterly and then easterly flow by the
conclusion of the weekend. With this shift in the flow, available
moisture will increase along with the chance of rain.

A mid-level trough will swing across the southeast on Wednesday
into Thursday, which could allow for a return of showers and
thunderstorms to south florida. All eyes will be on the
approaching thanksgiving holiday, which remains beyond this
forecast period, as the GFS features a potential cut off low that
begins to emerge from the pacific on its eastward journey towards
the gulf of mexico and possibly florida. This is still very far
out in time, well into the extended portions of the global
guidance, but does remind us we are entering the time of year
where severe weather potential could emerge for our region with
synoptic-scale systems.

Marine...

deteriorating marine conditions will overspread the waters as the
front clears through requiring a small craft advisory for the
atlantic and gulf waters into Friday. Biscayne bay and lake
okeechobee will experience cautionary conditions as well. Winds
and waves should begin to improve Friday into the weekend.

Beach forecast...

the gulf beaches will see an elevated rip current risk on the
backside of the cold front with the focus eventually shifting
towards the atlantic beaches for the weekend and the wind shifts
out of the north to northeast and the risk of rip currents builds.

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.
