Synopsis After a relatively cooler day today, offshore winds
will develop late tonight and during the day on Friday, bringing a
gradual warming trend to the region that will last through the
weekend. Gusty north to northeast winds are possible across the
north bay hills tonight and again tomorrow night. Cooler
conditions will return for the work week.

Discussion As of 2:00 pm pdt Thursday... Water vapor imagery
continues to show a trough of low pressure digging south across
the intermountain west and great basin this afternoon. Northern
california really remains on the dry side of the system, but
cooler conditions are prevailing across the region today. At this
time, more places are running 3 to 8 degrees cooler, with areas
trapped beneath the stratus are seeing the greatest cooling, such
as monterey and watsonville. This will make for a very pleasant
evening and a cool overnight conditions. Believe the immediate
coastal areas could see some drizzle again tonight, especially in
the vicinity of the monterey bay. Otherwise, the main story for
the night will be the developing offshore gradient across the
north bay hills. Models are showing that the 925 and 850 mb winds
ranging between 20 and 30 knots. At this time, think the ridge
tops could see some gusty conditions, but these gusty conditions
will remain below advisory criteria and be limited to the higher
elevations of napa, sonoma, and marin counties.

As high pressure will slowly begin to build back over the region
on Friday and for the weekend. As a result, a gradual warming
trend will develop across the region. Although the northerly winds
will weaken a bit for Friday, gusty winds will redevelop for
Friday night. Another trough will then dig along the pacific
northwest for the first part of next week, and remain in place
through at least the middle of next week. This will bring the
return of a deeper marine layer and cooler temperatures once
again. Palmer
