...Discussion from SFOFWFMTR...

 A pattern change is on the way, with a general cooling, moistening
trend and the possibility of wetting rains arriving this week. Winds
will begin to shift and become more onshore tonight, helping to
bring the cooler temps, moister air mass, and improved air quality
for many areas. Temperatures will  decrease a few to several degrees
each of the next 3 days,  returning to near normal temperatures by
mid week. Humidities will also increase given the cooler
temperatures and onshore flow. Some uncertainty regarding the
upcoming rains. There is a very minor (<5% chance) of elevated
convection tomorrow afternoon. Model data now indicates light
non-wetting warm sector precip arriving late morning Thursday, while
the main band of cold frontal precipitation arriving Thursday
evening through Friday morning. This system will bring wetting rains
to some areas but not others, with the best chance of wetting rains
over the North Bay mountains and hills, where fires are most active.
Much less precipitation is expected farther southward and/or at
lower elevations.
