An
upper level trough will approach the North Ops coast on Sunday and gradually
weaken as continues inland Sun night through Mon. Gusty W-SW winds will
continue through Greater Bay Area coastal gaps tonight through Sun morning
and strengthen further Sun afternoon and evening. Breezy S-SE winds push
north up the Sac Vly with SW winds from the Cascade/Sierra crest westward
strengthening in the afternoon and remaining locally strong through the
evening. Breezy though not as strong winds SW to NW winds will continue on
Mon favoring the Greater Bay Area as well as western, northern and eastern
portions of the area with lighter winds in central areas. Due to the
troughing influences afternoon mixing heights will remain good to excellent
in the N & E with moderate to locally lower mixing heights in marine
influenced western areas. |

to gradual decreasing trend in smoke dispersion conditions. Light northerly
flow will develop in the Sac Vly Mon night and continue into Tue with
generally lighter winds elsewhere. Shallow onshore flow will return to the
coast on Wed with locally breezy SW to NW winds favoring coastal gaps and
eastern areas Wed afternoon & evening and NW winds potentially beginning
