Discussion
Today... Latest analysis indicates central florida remains
underneath stacked high pressure extending from the western
atlantic. Ample moisture pooled along its western edge will
continue to feed northward and support another afternoon of near-
to above-climo coverage of storms. As is typical in light steering
flow patterns, the best chance for storms will exist across the
interior in the presence of greater diurnal heating and more
rigorous boundary interactions. With that said, light southerly
steering flow suggests initial convection will start close to the
coast, particularly south of CAPE canaveral. Guidance supports
this evolution with precip accumulating initially along the space
and treasure coasts early this afternoon, spreading inland and
then north thereafter. Have drawn pops of ~50% for most areas
save the volusia and northern brevard coasts where 30-40% should
suffice. Storm coverage will focus across the interior late in the
day since convection will be driven mainly by the sea-breezes.

Weak south to north steering flow will again lead to slow storm
motion with the potential for very heavy rainfall of 2 to 3
inches in a short period of time.

Tuesday-Thursday... Local pattern wl become more favorable for
rainfall coverage Tue as the subtropical ridge axis becomes nudged
south of the local area by a wave moving across the tn oh
valleys. Sufficient moisture and wly steering component wl lead to
development of sct to numerous aftn storms with the east coast
favored for some heavier rains. MOS indicates lower coverage as
some drying is shown Wed Thu but wl keep forecast somewhat higher
than what is indicated by guid mainly due to favorable steering
and suitable moisture for at least diurnal conv activity.

Extended... A general weakness in the sfc pressure field lingers off
the fl east coast and mid atlc seaboard through late week. There is
no sign of the subtropical bermuda ridge trying to re-establish
during the same period and with sufficient available moisture and
sfc heating, expect scattered storms to remain in the daily forecast
into the weekend. Steering level winds westerly at midweek wl
acquire more sly component toward weeks-end. This wl keep the local
area in suitable environment for measured rain potential daily with
a patchwork of measured rain distributed about the area and storms
shouldn't be particularly strong.

Aviation
Adequate moisture will support another active afternoon of shower
and storms. Initial development (between 15-18z) is indicated
close to our space and treasure coast terminals (kmlb- ksua) as
the atlantic sea breeze develops and pushes inland. Thereafter,
storm coverage will focus across the interior sites from mid to
late afternoon. Storms will pose similar threats as Sunday's, with
ifr vsbys and wind gusts of 30-45 knots near the strongest cores.

Marine
Today tonight... High pressure extending west from the atlantic and
across the central peninsula will result in prevailing light to
gentle south winds (outside of the sea breeze circulation). Seas 1
foot near the immediate coast, otherwise at or below 2 feet.

Scattered lightning storms are expected to develop along the
space and treasure coasts early this afternoon before shifting
inland with the atlantic sea breeze.

Tuesday-weekend... Ridge axis settling southward and weakening will
continue generally favorable open water boating conditions for the
upcoming week. South to southwest winds through midweek will remain
with a general southerly component into the weekend with winds
averaging around 10 kt and seas 3 ft or less offshore and around 2
ft near the coast. Winds and seas briefly higher near local
storms.
