.DISCUSSION...
Dry and quiet weather persists across interior NorCal today under
dry northwest flow. Locally breezy northerly wind gusts up to
15-25 mph are being observed across portions of the west side of
the Valley this afternoon. Winds will subside this evening.
Otherwise, cold morning lows with areas of frost are expected
Tuesday and Wednesday mornings, with Valley lows in the 30s.
Widespread freezing temperatures are not expected at this time.
The NBM has a 10 to 35% chance of temperatures in the Valley
reaching 32 degrees or lower on Tuesday morning, mainly along the
east side of the Valley. The NBM depicts a 20-40% probability of
visibilities less than a quarter mile Tuesday morning across
portions of the southern Sacramento and northern San Joaquin
valleys Tuesday morning. Thursday morning lows will be a little
warmer, with Valley lows in the 40s.

Ensembles show a weak shortwave passing through the Pacific
Northwest on Wednesday. This could bring some light showers across
portions of the Coastal Range, southern Cascades, and Shasta
County. The NBM projects a 20 to 45% chance of rainfall amounts
exceeding 0.10" across the northern Sacramento Valley and
surrounding higher terrain. Otherwise, dry weather is expected on
Thursday, with Valley high temperatures in the mid to upper 50s.
Precipitation chances return Thursday night as ensembles suggest
