Quiet weather to end the weekend and start the work week with quasi-
zonal flow aloft over the E Gulf of Mexico and Florida. Slightly
cooler weak surface high pressure to build into and move through the
region. Temps to run slightly below seasonal averages tonight
through Monday night then warming and moderating conditions Tuesday.

Models in good agreement with next southern stream storm system mid
to late week. Upper low currently over the Baja already spreading
upper cloud shield into the W Gulf. The low moves eastward and comes
in phase with northern stream trough to deepen forming longwave
trough thru the Plains states Wednesday. The associated surface low
pressure forms and moves along the Gulf Coast with increasing
southerly low level flow and moisture moving from the N Carib over S
FL to start rain chances into the local area Wed afternoon through
Thursday ahead of and along cold front. Upper energy to wrap over
the area for rounds of showers and thunderstorms with this system.
Lingering residual energy and moisture to keep light rain showers
for Friday as well.

Drier and cooler high pressure to build into the region next weekend.

Wave action along area beaches is subsiding this afternoon and will
allow high surf advisory to expire but rip current risk will linger
into early Monday.


Generally VFR conditions with mix of SCT locally BKN stratus and low
level cu clouds through this afternoon lifting tonight. May again
see some localized field fog at usual fog prone terminals towards


Large long period swells subsiding this afternoon to allow SCA to
expire. Weak pressure gradient to keep generally light winds
and slight seas later Monday into mid week. Next complex
storm system to move through the region Thursday into Saturday
with breezy winds to elevate choppy seas creating hazardous
marine conditions.


Recent rainfall, RHs above critical levels and fairly light winds to
prevent any fire weather concerns. Some patchy shallow fog will be
possible overnights especially in typical fog prone areas.
Also light winds will produce poor disperion values for
some areas Monday and Tuesday.
