Update
No changes needed to be made to the previous forecast as
everything looks on track. The main concern for tonight will be
the potential for patchy fog development across the interior and
west coast sections overnight into early Monday morning. The fog
could become dense in some spots during this time frame. On
Monday, the wind flow will start to shift more towards the south
southeast and there will be an increase in low level moisture as
well. At the same time, a weakening cold front will stall out over
central florida and then dissipate on Monday night and into
Tuesday. With the increase in the low level moisture, there could
be a few showers during the day on Monday. The best chances of
showers will remain in northern areas around the lake okeechobee
region.

primary concern overnight is low cloud and fog development over
the interior and gulf coast. This may bring a period of low
cigs vsbys to apf (and possibly tmb) late tonight. This should
remain west of mia fll pbi so will continue aVFR forecast at
these locations. It's not impossible that a brief lower cloud deck
sneaks in for a time towards sunrise, but not enough confidence to
carry anything in the tafs. A few showers are also possible
towards morning as well, but these should remain primarily
offshore over the atlantic waters.

an area of high pressure will continue to dominate the weather
pattern across south florida tonight. The main weather concern for
tonight will be the potential for patchy fog development over the
interior and west coast areas mainly during the overnight hours
into early Monday morning. The fog may become dense in some spots
reducing the visibility to one mile or less. Low temperatures
tonight will range from the mid 60s across the northwestern
interior sections to the mid 70s across the east coast. Any fog
that does develop will begin to dissipate after sunrise. During
the day on Monday, the flow will begin to shift to a more south
southeasterly direction. This will help to increase the amount of
low level moisture across south florida as well due to a weakening
cold front moving into central florida. This cold front will not
make it into south florida and it will stall out and dissipate to
the north. Spotty showers cannot be ruled out due to the
increase in low level moisture. The best chances of precipitation
will be across northern areas as well as the atlantic waters due
to the south to southeasterly flow.

Even though there will be a brief increase in low level moisture
on Monday, the mid to upper level ridge of high pressure will
continue to dominate the weather pattern throughout most of the
work week as it continues to strengthen as well. This will
continue to keep any impending systems off to the north. By the
middle of the week, winds will increase out of the southeast,
however, the flow will remain light enough to allow for a gulf
breeze to develop each afternoon.

High temperatures throughout the week will remain above normal
across the region. They are expected to get into the lower 80s
across the east coast areas to the upper 80s across interior
sections. Overnight low temperatures each night will remain on the
mild side as well as they will range from the mid 60s across the
northwestern interior to the lower 70s across the east coast metro
areas.

Marine...

an area of high pressure will continue to dominate the weather
pattern across the atlantic and gulf coastal waters early this
week. Winds will begin to shift around to the southeast early this
week and this flow will remain in place through the middle of the
week. Wind speeds across the local waters will increase by the
middle of the week due to a tightening pressure gradient. A
slight chance of showers cannot be ruled out across the atlantic
waters through the early portion of the week.

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.
