Update
Forecast looks on track for right now with most of the activity
along i-75. Showers and storms should start to weaken after sunset
with almost all the activity ending before midnight.

We are looking at a typical summertime seabreeze day tomorrow with
storms starting inland in the afternoon before slowly drifting
towards the coast by the late afternoon and evening hours.

Aviation
Vcts will stay in pie, tpa, lal, and srq through 03z tonight as
storms continue to flare up in the area. Tempo MVFR and ifr
conditions for the next couple of hours for tpa and pie where
storms are more likely. After that we can expectVFR conditions
overnight and in the morning before storms and vcts come back into
the tafs at 18z.

discussion (tonight - next Tuesday)...

little overall change to the forecast through the period as
mid upper level ridging will hold over florida through the work
week then shifts north over the eastern u.S. Over the weekend
before being suppressed south as a trough moves into the eastern
states early next week. Meanwhile at the surface the ridge axis
meanders over north central and central parts of the florida
peninsula through the period and gradually weakens some which will
allow the west coast sea breeze to move further inland.

For the rest of this afternoon scattered showers and thunderstorms
will continue to develop and move toward the west lingering around
the tampa bay area northward during the evening. Later this
evening and overnight we'll see mostly clear to partly cloudy
skies with any leftover convection moving well out into the gulf.

Through the weekend we'll see a pretty typical summertime pattern
with scattered mainly afternoon and evening convection each day
moving out into the gulf during the night. The location of the
subtropical ridge will be the main driving force in our day-to-day
thunderstorm coverage and location. Other than minor fluctuations
north to south, the ridge axis should generally set up over
central florida, which will allow afternoon sea breezes to push
steadily inland from the tampa bay area north. Sea breezes south
of tampa bay will have a tougher time moving inland against the
predominant east t southeast flow south of the axis.

Early next week the exact location of the subtropical ridge varies
between the models depending on how deep the trough gets over the
eastern states. For now it looks the axis will shift south some
into south central florida with a more southwest flow across the
nature coast with light southeast to south elsewhere. Plenty of
moisture will remain in place leading to more scattered showers
and thunderstorms.

Temperatures will be near to a couple of degrees above normal
through the period.

Marine...

a ridge of high pressure will provide light winds and slight seas
through the week with a shift to onshore each afternoon as the sea
breeze develops. Isolated to scattered convection will be
possible, especially during the nighttime and early morning hours.

Fire weather...

sufficient low level moisture will keep relative humidity values
above critical levels through the week with no red flag
conditions expected. No significant fog is expected through the
period.
