...Discussion from Monterey...

The marine layer remains compressed to around 1000  feet with poor
overnight recoveries (20-30%) and poor daytime  humidity retention
(10-30%) continuing above it. Conditions improve slightly Friday
into the weekend as the marine layer deepens to between 1000 to
1500 feet. This is caused by an approaching upper level trough that
will bring a cooling trend, improving daytime and overnight RH
values, cloudy mornings, and diurnally breezy afternoon and evening
winds across favored locations. The one exception will be the
interior Central Coast where hot, dry daytime conditions prevail
through the forecast period.

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