update...

a few showers have developed over the southern atlantic waters
early this evening. The showers should continue to develop tonight
and work into the east coast metro areas. Therefore, isolated
showers have been added for this evening and will continue through
the overnight hours for the east coast metro areas and the
atlantic waters. Rest of the forecast looks good at this time and
no other changes are planned.

Update... 54/bnb

discussion...

high pressure will remain over the western atlantic waters tonight
into Sunday night, as a low pressure system moves slowly
northeast through the central united states. This will keep a
tight pressure gradient over south florida with breezy to windy
easterly winds. There could also be a few showers over the east
coast and the atlantic waters through Sunday night. Therefore, a
slight chance of showers have been added to the east coast metro
areas and the atlantic waters through Sunday night.

The aforementioned high will then weaken early next week over the
western atlantic waters, as the low over the central united
states moves northeast into the great lakes. This will allow for a
cold front over the central states to move southward into the
southeastern united states. The winds will be more southerly
allowing for some deeper moisture to work into the area from the
south. Therefore, the threat of thunderstorms is still possible
over the interior areas along with scattered showers, and only a
slight chance of showers along the metro areas.

The strong easterly wind flow will also allow for near record
highs over the west coast metro areas of south florida on Sunday.

More on this in the climate section below.

Extended forecast...

the high will continue to weaken over the western atlantic waters
late this week, as the cold front over the southeastern united
states moves southward and washes out over south florida by early
next weekend. The moisture associated with the front will be
mostly gone by that time, as the front gets into south florida.

Therefore, there will only be a low-end chance of showers over
south florida late this week.

Marine...

the winds will be easterly around 20 knots over most of south
florida waters tonight into Sunday, except for the the near-shore
gulf waters and lake okeechobee waters where the speeds will be 15
to 20 knots. This will allow for the seas in the atlantic waters
to be up to 6 feet, while the gulf waters remain below 6 feet
through Sunday. Therefore, an SCA is in place for the atlantic,
offshore gulf, and biscayne bay waters through at least Sunday.

There is also a scec in place for the near-shore gulf and lake
okeechobee water through Sunday.

Beach forecast...

the breezy to windy easterly wind flow will also allow for the
continuation of the high risk of rip currents through Sunday
night.

Fire weather...

the relative humidity over the west coast metro areas and inland
areas of collier county should fall into the mid to upper 30s
Sunday afternoon, as the 20 foot winds should be around 10 to 15
mph. Therefore, a fire weather watch has been issued for the
interior and metro areas of collier county for Sunday afternoon.

Climate...

the high temperature at naples today got up to 95 degrees which
broke the old record of 92 degrees set in 1996 and tied the all-
time high for the month of april which was set back in april 14,
1965. The high temperature for Sunday at naples is 93 degrees and
the record for Sunday is 93 degrees set in 1991.

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.
