Update
Satellite and radar data this morning show a few showers lingering
over the atlantic offshore waters, while low level CU are starting
to develop over land across the metro areas.

Latest observations depict a generally southeasterly flow
prevailing across the area, which will be enhanced this afternoon
as sea breezes develop. Only exception will be over the gulf
coast where southwesterly flow will develop as the sea breezes
push inland. This overall flow pattern will again favor showers
over interior and western areas, but a brief shower is still
possible over the atlantic coast metro areas.

No significant changes are required for the morning forecast
update, with afternoon highs today expected in the upper 80s to
lower 90s.

aviation...

vfr conditions prevail through most of the period ending at
12z Tuesday. Expect scattered showers developing along the
interior and west mainly affecting apf terminal while the
east remains dry with no restrictions. Light and variable
winds will become southeast around 8-13 knots by the late
morning hours at the east coast sites, and southwesterly
with the gulf sea breeze at kapf.

Prev discussion... /issued 343 am edt Mon may 22 2017/

Strong to even severe storms are possible Wednesday into Thursday
Discussion...

today through Tuesday...

high pressure over the western atlantic waters will move east through
Tuesday allowing for a cold front over the tennessee valley to move
southeast into the southeastern united states. This will allow for
the steering flow over south florida to be southeast today before
swinging to more of a southerly direction on Tuesday. The east and
west coast sea breezes will also develop each day and push inland.

Therefore... The best chance of showers and thunderstorms this
afternoon and again on Tuesday afternoon will be over the interior
areas of south florida.

Wednesday through Thursday...

a trough of low pressure over the northwestern united states will
move southeast and strengthen as it moves into the tennessee
valley by middle of this week. This in turn will allow for the
front over the southeastern united states to move southward into
northern florida, and allow for the steering flow over south
florida to be south/southwest bringing in deep tropical moisture
to the area. Therefore, numerous showers and thunderstorms should
develop over south florida Wednesday into Thursday.

A mid to upper level jet 100 to 130 knots will be moving around
the base of the trough through northern/central florida middle of
this week, as a low level jet of 50 knots will be moving through
central florida during. This will allow for some of the
thunderstorms to become strong to even severe over south florida
Wednesday into Thursday. SPC has also put the northern areas of
south florida in a slight risk of severe storms with rest of south
florida in a marginal risk of severe storms for Wednesday.

The primary impacts at this time will be likely gusty to damaging
winds, but a tornado or two can not be rule out over south
florida.

Extended forecast...

the trough of low pressure will continue to move east into the
western atlantic waters late this week into this weekend, as the
front moves into south florida and stall out. This will allow for
the tropical moisture to remain in place over south florida, and
allow for the sea breezes to develop and push inland each day.

Therefore, isolated to scattered showers and thunderstorms should
develop each afternoon with the best coverage over the interior
areas.

Marine...

the winds will be southeasterly today around 10 knots before
swinging to more of a southerly direction on Tuesday and
increasing to around 15 knots. The winds will then continue to
swing to a southwesterly direction on Wednesday and increase to
breezy conditions. The seas will remain below 6 feet in both the
atlantic and gulf waters of south florida through middle of this
week. The southeasterly winds along with low tide today will lead
to an moderate risk of rip currents along the east coast beaches
of south florida today.

Fire weather...

the relative humidity over south florida should remain above the
critical values through middle of this week, except over glades
county for this afternoon. The relative humidities could fall down
into the mid to upper 30s this afternoon over glades county for
couple of hours, but the 20 foot winds will remain below 10 mph.

Therefore, no fire weather headlines is expected over glades
county or rest of south florida through middle of this week.

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.
