Dry and mild weather will continue to dominate Northern California
through early next week. Some occasional high clouds from time to
time but no precipitation. Middle to end of next week could change
that as a weather system looks to move in from the south.


High clouds continue to stream over the NorCal with light winds.
Overnight lows will be about 5 degrees above normal generally
upper 50`s/low 60`s for valleys. Current forecast is on track and
no update needed.


.PREVIOUS DISCUSSION (Tonight through Monday)
High clouds from a weather system over the Gulf of Alaska is
doing little to cool our temperatures. Drier air is expected to
move in tomorrow for more sunshine and temperatures once again
above normal, but only by a few degrees. Saturday and Sunday, a
disturbance off the main Gulf of Alaska weather system will move
through the Pacific Northwest. This system will bring more clouds,
slightly cooler temperatures (back down to normal) and some
breezy winds...mainly over the higher terrain in the Shasta and
Lassen areas. Weak ridging will bring sunshine back and bump
temperatures back above normal Monday.



Broad upper ridging continues over Interior NorCal through early
next week with dry weather and above normal temperatures. Closed
upper low off the Baja coast will slowly drift north toward
central California middle of the week. Some model discrepancie
with how far north the system and associated moisture will get.
That being said, they do agree on some weather disturbance moving
toward the region. Therefore increased clouds and lowered
temperatures and introduced some isolated showers to the Central
Sacramento valley and locations south.



Just high clouds over airfields through early Friday. Variable
light winds will prevail with the exception of the delta breeze
early Friday morning. Speeds are expected to be less than 15 mph
through the delta.
