.DISCUSSION...
Rather straightforward typical summertime regime at the surface
despite upper level large amplitude troughing over the eastern
U.S. and high amplitude ridging in the west. Dry column moisture
on WNW flow limiting convection to just isolated coverage mainly
along the SW LA coast this afternoon. Still some daylight for
isolated one or two storms this afternoon near the coast, but
window closes at sunset. Persistence is the rule through the
weekend into early next week with a slow but steady increase in
low level and column moisture as surface flow eventually become
more onshore oriented early next week to bring daily rain chances
closer to climatological norms by Saturday, perhaps slightly
higher rain chances by next Tuesday. Temperatures should warm a
couple of degrees more Thursday and Friday, then trending to near
normal as moisture increases over the weekend, in line with
typical summer land/sea breeze regime.

&&

.AVIATION...
VFR prevailing at all locations next 30 hours. Convection should
remain minimal in coverage...although KHUM may show brief showers
around 19Z to 21Z due to sea breeze boundary.

&&

.MARINE...
Weak high pressure regime over the gulf to maintain relatively
light winds and low seas through Saturday. There is some
indications of a easterly swell train emanating from the Florida
Straits Saturday that may produce a 7-8 second period for a short
duration to impart a ground swell to augment an otherwise flat
wind wave in the open waters before dampening later Saturday
evening.
