.DISCUSSION...
Issued at 306 AM EDT Mon Jun 24 2024
A strong U/L ridge over the southern plains will extend over the
Florida peninsula through Tuesday, but will slowly retrograde
toward the desert southwest. By Wednesday, a weakness in the
subtropical ridge will allow a weak U/L trough to sink south over
the Florida peninsula Wednesday and Thursday. On Friday and
Friday night, a digging S/W disturbance will push across the
northern plains inducing ridging downstream across the southern
Mississippi river valley and southeast U.S., including Florida.
This will cause the trough to fill, with the building U/L ridge
holding over the forecast area through the weekend.

At the surface, bit of a transition day today as a weakening
frontal boundary stalls across north Florida. This will suppress
the surface ridge axis south of the forecast area with westerly
flow developing. This pattern promotes scattered late
night/morning showers and thunderstorms over the near shore
waters advecting locally onshore the coastal counties, spreading
inland and increasing in areal coverage during the afternoon
hours. This pattern is expected to hold through the upcoming week.

Highly uncertain long range outlook as pattern change possible
next weekend as broad easterly flow may develop. This would shift
highest pops to the coastal counties along the west coast sea
breeze boundary during the late afternoon/early evening hours.
However, building U/L ridge over the region may advect drier air
aloft across the forecast area which combined with increasing
large scale subsidence would suppress pops.

.AVIATION...
(06Z TAFS)
Issued at 306 AM EDT Mon Jun 24 2024
Predominately VFR conditions expected today. Scattered showers and
thunderstorms will develop by this afternoon across west central
and southwest Florida and may potential impact terminals for a few
hours with LCL MVFR CIGs and IFR VSBYs.

.MARINE...
Issued at 306 AM EDT Mon Jun 24 2024
Winds and seas expected to remain below SCEC levels through the
week as relatively weak westerly flow will prevail. Main hazard
would be locally gusty winds and rough seas due to thunderstorms,
primarily during the overnight and early morning hours.

&&

.FIRE WEATHER...
Issued at 306 AM EDT Mon Jun 24 2024
No fire weather hazards are expected through the week as
sufficient moisture will keep minimum afternoon relative humidity
values above critical levels each day.
