800 pm edt Wed mar 20 2019

Aviation Weak front sliding down state this eve. East coast
likely to vary between NE and N next few hours, becoming more
nnw as front gets closer. Kapf will be exception, remaining nne-
ne overnight. -shra will continue until wind shift, though
activity may brush kfll through overnight. Can't rule out brief
MVFR CIGS vsbys with shra, though overall things remainVFR with
lowest CIGS bkn040-050. Nnw winds prevail into Thursday, becoming
gusty after 15z with potential for east coast sites to become nne
or even NE late afternoon. Drier conditions are expected.

Update
The trough of low pressure over the lake okeechobee region early this
evening will continue to move southward through south florida late
this evening and should be south of the area after midnight.

This will allow for the northeast winds over the area to become
more northerly after midnight and allow for the showers affecting
the region this evening to mostly end after midnight. The only
exception to this is for the east coastal areas where there could
still be a few showers after midnight.

The seas have continue to fall below 7 feet in the atlantic waters
of broward and miami-dade counties early this evening. Therefore,
the SCA will be replace with a scec condition this evening.

The high risk of rip currents will also be allowed to expire at 8
pm edt this evening for the east coast beaches of south florida.

Rest of the forecast looks good at this time and no other changes
are planned at this time.

Prev discussion issued 405 pm edt Wed mar 20 2019

Cooler and drier weather late this week followed by a warming
trend this weekend...

Above normal predicted astronomical high tides late this week
east coast beaches...

discussion...

tonight...

low pressure over the western atlantic waters will
continue to move east further into the atlantic waters tonight
allowing for a trough extending southwest into central florida to
move southward through south florida this evening. This will allow
for the northeast winds to swing more northerly late tonight over
south florida and take the low level moisture southward over the
mainland, but the low level moisture will still remain in place
over the atlantic waters tonight. Therefore, isolated to scattered
showers are still possible over the east coast metro areas this
evening ahead of the front before drying out late tonight. The
atlantic waters will still see isolated to scattered showers for
most of tonight.

Thursday and Friday... A cold front over the tennessee valley
will be moving southward tonight into northern florida before
moving down the florida peninsula on Thursday morning and through
south florida Thursday afternoon. High pressure will then build
into the area for Friday. This will allow for much drier and
cooler weather to work into south florida Thursday night through
Friday night.

Lows on Thursday night will be in the lower to mid 50s over most
of south florida except for the southeastern areas where it will
be in the mid to upper 50s and west of lake okeechobee where it
will be in the mid to upper 40s. Winds will also be from 5 to 10
mph over the metro areas Thursday night allowing for the wind
chills to be from upper 40s to lower 50s over metro palm beach to
around 50 over metro broward to lower to mid 50s over metro
miami-dade, except around 50 over the redlands area and over
metro collier county. The interior areas will see light and
variable winds Thursday night allowing for the apparent low
temperatures to be the same as the forecast low temperatures.

Lows on Friday night will range from the upper 40s to lower 50s
over the interior and west coast metro areas to lower to mid 50s
over the east coast metro areas, except mid to upper 40s west of
lake okeechobee. Highs on Thursday and Friday will be upper 70s to
lower 80s, except mid 70s west of lake okeechobee.

Extended forecast...

the high will move slowly east into the western atlantic waters
this weekend allowing for more of an easterly wind flow to set up
over south florida allowing for a warming trend to set up. The dry
weather will also remain in place over south florida this weekend.

Early next week, low pressure should develop over the central
united states and move northeast towards the great lakes. This
will allow for a cold front associated with the low to move
southeast into the northern florida. This in turn will allow for
more of a southwest wind flow over south florida bringing back
some low level moisture leading to a slight chance of showers
mainly to the east coast metro areas.

Marine...

the northeast winds of 10 to 15 knots will slowly back to a
northerly direction late tonight into Thursday. The winds will
continue to back to a northwest direction Thursday night behind
the passage of the cold front and increase to breezy conditions.

The winds will then swing to an easterly direction this weekend
while decreasing to less than 10 knots.

The atlantic seas will continue to slowly decrease from 5 to 7
feet in palm beach waters tonight to 4 to 6 feet Thursday into
Friday. Rest of the atlantic waters will remain in the 4 to 6 feet
through Friday. The atlantic waters will then decrease to 3 feet
or less this weekend. The gulf waters of south florida will remain
at 4 feet or less late this week into this weekend. Therefore, the
sca will be allowed to expire this evening for most of the
atlantic waters except for palm beach where the SCA will remain in
effect until Thursday morning.

The tide levels along the atlantic beaches are running about a
foot over the predict astronomical tides due to the super full
moon. These tide levels will lead to some minor ponding along the
typical vulnerable areas along the east coastlines of south
florida during high tides through Thursday night.

beach forecast...

the threat of rip currents will be decreasing tonight into
Thursday for the east coast beaches, due to the winds backing to a
northerly direction. At the same time, the threat of rip currents
will be increasing along the west coast beaches of south florida
for the same reason. Therefore, the high risk of rip currents will
be allowed to expire along the east coast beaches this evening.

This weekend the threat of rip currents will be increasing along
the east coast beaches and decreasing along the west coast
beaches as the winds become easterly again.

Fire weather...

the dry air over south florida late this week will allow for the
relative humidity to fall into the 40s on Thursday, but on Friday
the relative humidity will fall into the upper 20s to lower 30s.

However, the 20 foot winds will remain below 15 mph over south
florida on Friday. Therefore, no fire weather watches are
expected at this time over south florida for Friday.

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.
