Discussion
Thru tonight... Outflow boundary from previous early morning
convection continues to slowly push southward across metro orlando
and north brevard, sparking scattered lightning storms. The east
coast sea breeze formed earlier but has been pinned at the coast
by stout SW flow. And drier air south of the CAPE has kept the sea
breeze free of convection. Nonetheless, the outflow boundary and
assocd storms should zipper down the sea breeze over brevard
county and spark additional storms into early evening. It looks
like storms will not end as early as previous days as late
boundary collisions across the south interior may keep isolated
showers storms going past sunset.

Tue-wed (modified)... Mid-level (500 mb) ridge builds northward
across south fl as troughiness shifts NE while surface atlc ridge
holds directly underneath. As a result, deep layer moisture
temporarily lessens Tue from very moist profiles of late,
averaging 1.6-1.8 inches precipitable water Tue (lowest across the
north half of cwa), followed by surge of deeper moisture
northward wed, especially across the south half of the area, where
pw values should return to 2.0 inches. Since we should see
noticeably lower overall storm coverage orlando north, have
lowered pops and raised MAX temps showing widespread mid 90s both
days over the interior. Lingering evening convection both days,
with few onshore- moving late night showers storms along lower
treasure coast early wed, south of ridge axis.

Thu-sun (previous)... Ridge surface and aloft persists across
southern half of fl through late week then is surpressed a bit
farther south as mid level trough and surface reflection extend
southward to panhandle over the weekend. Band of high pw lifts
slowly north from southern to central cwa, locally enhancing storm
coverage. However, main feature will be extended period of W sw
steering flow which will move diurnal convection from western
peninsula to interior portions mid day early afternoon, then to
eastern side of the peninsula mid late afternoon. Surface flow
should remain light enough through the week to allow east coast
sea breeze to form and enhance coverage intensity of storms as
they approach the coast. Offshore gradient flow may become strong
enough, at least over the northern half of area, to limit restrict
sea breeze formation over the weekend, but proximity of trough
should overcome lack of sea breeze convergence to lead to above
normal weekend pops. MAX temps near climo inland and a few degrees
above normal along east coast, with mins generally remaining
several degrees above normal.

Aviation
Slow moving outflow boundary pushing south from tix-ism will
produce scattered tsra at or near tix mco ism through 22z and
eventually mlb and possibly vrb closer to 00z. ThenVFR overnight
and early Tue with scattered tsra developing south of mlb aft 16z.

Marine
With weak ridge over southern waters, winds generally s-sw 10 kt,
turning onshore in a sea breeze near the coast each afternoon.

Seas 1-2 ft nearshore and up to 3 ft offshore. Focus for afternoon
storms will be from the CAPE southward through mid week.
