Scientific Forecaster Discussion
Area forecast discussion
National Weather Service Sacramento California
216 PM PDT Thursday Oct 8 2015
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.
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, by a few
degrees. Saturday and Sunday, a disturbance of 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
extended discussion (tuesday through thursday)
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 discrepancies
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.
