Update
Increasing rain chances through Tuesday...

current... E-w oriented surface front has stalled and become rather
diffuse across the central peninsula this morning. Temperature and
dewpoint discontinuities have broadened in brisk onshore easterly
flow, which has now overspread the entire cwa, bridging the boundary
in the process. Both ccafs drwp and kxmr RAOB data indicate a stout
20kt of easterly flow up through around 800mb 6kft, with 1.4" of
pwat below a weak cap just above 700mb. Vis IR satellite imagery
show multi-layered clouds over the cwa, with a widespread high cloud
canopy over the southern CWA thinning as it pushes ese. This is
associated with a weak, e-w short wave trough vortlobe sliding east
across the peninsula. Local 88d radar shows a persistent e-w band of
showers extending from the atlantic onshore CAPE canaveral, with
isolated activity over the remainder of the CWA and local atlantic.

Remainder of today... Breezy to windy conditions on tap for this
afternoon with an ample amount of low level moisture in place to
help generate diurnally enhanced showers. While the local thermal
profile is generally supportive of ts, given the forecast available
cape, the low level wind profile is decidedly not. The magnitude of
onshore will portend both a strong marine influence (coupled with
coverage of clouds showers) which will modify low level heating
somewhat, and prevent any semblance of an ecsb from developing. This
leaves the only available source of low level convergence as the
increasingly diffuse frontal boundary. Based on RUC analys fields,
the mid upper contributions to forcing (h50 PVA h25 divergence) are
about as strong as they well get right now, and will only wane and
shift south offshore with time. So while there is a "slgt chc" for
thunder in the current forecast, it appears to be quite small.

Given the local radar trends, which aren't showing any more of a
southward push to the precip band, plan to shift the higher pops
a little farther northward than previously advertised, with likely
(60) indicated for north brevard volusia seminole and east orange.

Scattered pops elsewhere. Other tweaks to the winds skies temps
will be minimal.

Aviation Most areas showingVFR to MVFR CIGS bkn025-035. Expect
this trend to continue, mainly in the bkn030-050, with increasing
coverage of MVFR showers, and some ifr vsbys in more intense precip
cores this afternoon.

Marine No changes. Solid 20-22kt+ of easterly flow has overspread
the remainder of the maor, with seas having built to 5-7ft near
shore and 8-9ft well offshore. SCA continues areawide, as does the
bhs issued this morning for rough, choppy surf and a moderate rip
current risk.
