Area forecast discussion 
National Weather Service Sacramento California
354 PM PDT Thursday Aug 25 2016

dry weather pattern with near normal temperatures for the rest of
the week.


Short term discussion (today through sunday)...
a short wave currently over norcal, which is evident in water
vapor imagery, has limited moisture and dynamics, and we didn't
even have much cumulus, let alone any thunderstorm activity.

Currently, the marine layer is around 1800 ft deep which is
up a couple hundred feet from 24 hours ago. This, combined with
the moderate/strong onshore gradient will continue to bring
slightly below normal temperatures Friday for the Delta and
adjacent areas.

A weak longwave ridge will build in Saturday and Sunday but will
have relatively little influence on our temperatures.

extended discussion (monday through thursday)
a short wave trough should approach interior northern California
early next week. Model differences still exist regarding the
progression of the approaching trough, with the GFS being the
fastest solution. A deeper wave will move along the West Coast by
midweek, resulting in synoptic cooling during the extended period.
Temperatures will be near to below normal temperatures next week.
Precipitation chances are low at this point, given that the air
mass looks to be dry for convection.


VFR conditions across taf sites next 24 hours. Generally light
winds except for gusts up to 30 knots near the Delta Region.
