Update
Transition to southwest flow underway across the region... With
morning 12z ktbw sounding reflecting west to southwest flow up to
around 500 mb. Flow is still relatively light over the lowest
3 kilometers... Generally 5 to 10 knots... Which favors coastal
showers and storms during the morning hours then spreading inland
throughout the afternoon. This lines up pretty well with the
existing forecast therefore no significant changes required at
this time.

Aviation
Vfr early across terminals... With the exception of klal which has
had shallow br fg intermittently throughout the morning but
should burn off with daytime heating ensuing following sunrise.

Early lgt vrb conditions will increase to southwest 6 to 10 kts
by 14-15z across terminals before decreasing back to lgt vrb
again overnight at southern terminals. Reductions to MVFR ifr due
to passing shra tsra expected at coastal terminals as early as
14z... With predominantlyVFR conditions returning after 01z or so
as lingering evening convection wanes.

discussion...

a mid level trough centered over eastern canada extending into the
southeastern us will slowly rotate through the eastern seaboard
today and Wednesday. At the surface, the subtropical ridge axis
stretching from the atlantic across northern florida will be
shunted southeast through Wednesday as a surface trough digs into
northern florida and the northeastern gulf of mexico, setting up
southwesterly flow over the forecast area, holding through
Thursday. This pattern will favor deep moisture advecting across
the area, with showers and storms developing over the gulf waters
during the early morning hours each day and shifting onshore
through the morning and afternoon and into the interior through
the early evening. Upper level support from the trough moving into
the area will cause the highest storm chances of the week on
Wednesday and Thursday, with heavy rainfall and isolated flooding
possible, especially over the nature coast.

The mid level trough will break down Friday through the weekend
with weak ridging building in across florida from the atlantic.

A broad surface ridge will build into the mid atlantic region
during the weekend and into early next week, allowing surface flow
across florida to return to easterly. Deep moisture will continue
to produce scattered to numerous thunderstorms each afternoon,
with the highest chances shifting just inland of the west coast
with the afternoon sea breeze collision.

Aviation...

generallyVFR conditions will hold through mid morning, although
some patchy fog is possible around sunrise. Scattered showers and
thunderstorms will move east through the area from mid morning
through the early evening, with periods of reduced flight
categories possible as storms approach individual terminals.

Marine...

high pressure east of florida will shift southeast today and
tonight as a surface trough pushes south into the northeastern
gulf, with winds becoming southwesterly to westerly. Winds will
generally remain less than 15 knots with seas of no more than 3
feet, although locally higher winds and seas are expected in the
vicinity of daily thunderstorms. Storms will typically form over
the gulf waters and move onshore through the morning and afternoon
hours.

Fire weather...

humidity will remain well above critical levels through the next
several days.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
