...Discussion from Los Angeles/Oxnard...

A weak upper level high pressure system combined with weakening
onshore flow shrunk the marine layer depth considerably this
morning. This brought a substantial warming and drying trend for
interior areas, along with weaker winds. The marine layer depth is
expected to continue to shrink tonight into Friday, with  a few more
degrees of warming anticipated across interior areas. Some mid level
moisture and instability will likely generate some afternoon cloud
buildups each afternoon from  Friday through Sunday across the local
mountains, especially Ventura and Santa Barbara counties. As a weak
upper level low pressure system develops off the coast this weekend
into early next week, looking for marine layer clouds to become more
widespread across coastal and valley areas while bringing a cooling
trend to much of the region.


...Discussion from Monterey...

Temperatures will continue to warm into the weekend as high pressure
builds over the Eastern Pacific. The marine layer may compress a bit
over the next few days but will remain  prominently along the coast
resulting in night and morning low  clouds and moderate temperatures
along the coast. Temperatures will cool slight next week as the high
weakens and cold front approaches the region.

Note : All winds are 20-foot Winds Unless otherwise specified.
Thunderstorms imply strong, gusty and erratic winds.
