...Discussion from Monterey...

ERC values continue to be around or below the 50th  percentile
across our area. Nighttime RH recovery will be good  from locations
generally impacted by the marine layer through the  end of the week,
along with daytime highs at or slightly below  normal. A gradual
warming trend looks to set in for the weekend  into the beginning of
next week.

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



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

This afternoon and tomorrow afternoon there are lingering chances of
 mountains showers and thunderstorms. There is a 5-20% chance of
precipitation across the highest elevation mountains of LA and
Ventura  Counties, with the greatest chances over the eastern San
Gabriel  Mountains this afternoon. There remains a small chance of
dry lighting  and gusty winds if a storm were to develop, which may
result in a fire  start and erratic fire behavior.

The `June Gloom` deep marine layer will continue through Thursday,
becoming shallowing Friday into the weekend with a gradual warming
trend away from the immediate coast. Onshore flow will prevail,
yielding  gusty winds across the interior, especially the Antelope
Valley and  foothill during the afternoon and evening. Expect peak
gusts of around  25 to 45 mph to be common.

Lower humidities between 12 and 25 percent will affect the higher
elevations, interior valleys and the Antelope Valley through the
weekend, thus there will continue to be a persistent risk of grass
fires.
