Update
Scattered to numerous showers (with embedded thunderstorms)
continue their northward push across the atlantic waters and
adjacent east coast metro areas. Expect a brief lull as these
showers pull away before surface heating aids in rapid redevelopment
during the late morning and early afternoon hours. Decently
strong low-level east southeast flow will keep movement fairly
progressive today, but we'll need to watch for potential training
of cells over the same areas. If this occurs minor flooding could
become a concern. Otherwise lightning and brief gusty winds are
the primary hazards anticipated from thunderstorms today. A few
waterspouts are also possible over the atlantic and gulf waters.

Updated the forecast to account for radar and satellite trends,
along with the latest solutions provided via the convection
allowing mesoscale models. Otherwise the forecast is in good
shape, and no major changes are anticipated through the morning
hours.

numerous light to moderate rain showers will impact the eastern
terminals through the morning hours, with an embedded thunderstorm
possible. Thereafter, showers and storms will become more
scattered by mid to late afternoon, while gradually pushing
inland towards the gulf coast. Temporary low ceilings and
visibilities are possible in thunderstorms, along with gusty and
erratic winds. Prevailing easterly surface winds will continue
through the TAF period.

today and tonight: latest tafb surface analysis has a trough
oriented over the southern florida peninsula. Overnight most of
the convection has stayed south of the region and out of the
atlantic waters in the florida straits. However, some activity is
beginning to develop over the atlantic and the southern tip of
the peninsula. As the trough continues to work through the region
precipitable water values derived by satellite are around 1.9
inches. Therefore there is plenty of moisture that will lead to an
increase in shower and thunderstorm activity today. Most of the
activity will still be diurnally driven with east southeasterly
flow. The east coast will see a better chance of showers and
thunderstorms in the morning and early afternoon before activity
will concentrate over the interior and gulf coast. Main hazards
with activity today will be gusty winds, occasional to frequent
lightning strikes and locally heavy rainfall.

We have had some time to recover the past few days from recent heavy
rainfall last week and that is noticeable in the latest flash flood
guidance as those values have increased. However, any storms that
has high rainfall rates or a line of storms moving onshore or over
the same area may cause minor street flooding and flooding in low-
lying poor drainage areas.

Most of the convection will begin to diminish across the region and
push offshore around sunset. Activity overnight will focus over
the waters. Overnight lows will be in the mid to upper 70s to
near 80 along the coast.

Wednesday and Thursday: as the surface trough exits the region a
return to a typical south florida summertime pattern for the
middle part of the week with southeasterly flow persisting. A
little bit of drier air works into the region on Thursday for the
lowest rain chances of the week only around 30 percent. This will
be short lived as there will be an increase in moisture and
precip chances as we move into the weekend.

Friday into the weekend: Friday into the weekend will see another
moisture surge into the region. As the northern portion of a
tropical wave will break off into a surface trough and move
towards south florida. This will lead to an increase in rain
chances beginning Friday through the weekend. While it does not
look like a complete washout, as convection will still be
diurnally driven, showers and thunderstorms chances increase
during the day. The moisture will remain across the area as a high
pressure develops in the gulf with winds becoming more southerly
continuing the moisture increase as we end the weekend and move
into next week.

Marine...

east southeasterly winds will prevail throughout the end of the
week. Seas will be generally 2-3 feet in the atlantic, and 2 feet
or less in the gulf. Showers and thunderstorms will be possible
each day and night over the local south florida waters. Gusty and
erratic winds with locally higher seas are possible in and around
any convection.

Beach forecast...

east southeasterly wind flow will allow for a moderate risk of
rip currents at the atlantic beaches. The elevated risk of rip
currents may persist the next few days.
