911 am PDT sun Aug 30 2015
dry with mostly below normal temperatures this week.
a broad trough will remain over the region today. Temperatures
are running a little cooler today down 5 to 10 degrees from
yesterday. A few clouds will move across the interior today
otherwise expect mostly sunny skies.
The current trough over the region will lift northeast this
evening but another trough will drop down along the coast from
Canada Tuesday and Wednesday to help keep temperatures cooler
than normal through at least mid week. This trough does not look
like it will bring any precipitation to the interior at this time.
The trough will likely generate breezy conditions Tuesday and
Wednesday as it deepens for the interior.
Extended discussion (thursday through sunday)
Norcal will remain under the influence of a large scale trough
pattern through the end of the week. This will likely keep temps
below average. The GFS and ec continues to hint at a deeper
trough trough Thursday bringing precipitation to far northern California
near the or border, but the model consensus leaves things dry
The trough is forecast to lift out to the northeast over the
weekend allowing short-wave ridging to rebuild across norcal. This
may allow temps to climb back above average with the warmest
valley readings returning to the mid 90s.
VFR conds cont. Generally light winds with gusts 15-25 mph
through the Carquinez Strait and West Delta.
