Generally quiet weather is forecast into next week. Periods of breezy winds and passing clouds with mild temperatures continue. Light mountain showers are possible Saturday and again early Monday. Dry, breezy, and warm conditions possible mid-week next week.
Short wave ridging will build in over NorCal today. This is going to bring quiet conditions with warmer temperatures. We will see some increased northerly flow today but overall it will not be very strong, a few gusts to 20 mph will be possible from the central Sacramento Valley south into the northern San Joaquin Valley. Passing high clouds associated with a trough digging into the PacNW can also be expected throughout the day. The trough pushing into the PacNW today will continue to dig south and will brush the far northern part of the state on Saturday. Not expecting much in the way of precip with this system and the latest NBM PoPs have come down quite a bit but a few light showers will be possible over the Shasta County Mountains.
Short wave ridging returns for Sunday with another trough tracking just to our north on Monday. Once again mainly dry conditions can be expected with this system with only a slight chance for a few light showers over the Shasta County Mountains. Increased onshore winds can be expected on Monday ahead of the trough with winds through the Delta and over the Sierra gusting 20-35 mph. Northerly flow then develops Monday night as the trough pushes to the south and east. Gradual warming continues over the weekend with slight cooling Monday.
Extended Discussion (Tuesday through Friday)
Significant warming with gusty north to east wind and lowering humidity expected Tuesday into Wednesday as EPAC high builds inland. By Wednesday, high temperatures in the Central Valley forecast in the upper 80s to around 90, about 10 to 15 degrees above normal.
Next short wave trough progged into the West Coast Thursday, however differences exist with depth of wave. Main impact will be some synoptic cooling with NBM advertising a threat of showers mainly over the Shasta mountains Thursday. Dry weather expected Friday under influence of upper ridge.
