Summary A weak low pressure system off the California/Oregon coast has moved close enough to the coastline to deepen the marine layer. The latest sounding indicates the marine layer has deepened to 2,800 feet. That’s plenty deep enough to allow modified ocean air to move down the valley. The last observation at Travis AFB indicated winds out of the southwest at 19mph gusting to 25. Readings will likely head south and end up in the low 90s today and Saturday then begin warming Sunday through Wednesday as high pressure over north Texas expands westward towards southern California with readings nearing the century mark Monday through Wednesday before the off shore low once again moves inland through Oregon around Thursday of next week for the beginning of our next warming trend. Models show a dry, southwesterly flow continuing which will mean most clear skies for the next week or so.
Forecast Mostly clear skies through Tuesday. Mostly clear Tuesday night through Friday.

Two Week Outlook: September 1 through September 7 This model shows a rather active monsoonal flow into the Desert Southwest and possibly California. This model shows above average precipitation over the Sierra Nevada but I’ll play the odds for now and leave the forecast dry for the valley floor. temperatures should be seasonal.
August: This model indicates temperatures over the next 30 days will be near to slightly above seasonal averages. Dry weather will continue, although we will have to keep a watchful eye to the south for possible tropical activity.
August, September, October: This model shows above average temperatures for much of the west, particularly the Desert Southwest. It also points to below average precipitation over the Desert Southwest, possibly meaning a less active monsoon season. The chance of precipitation for central California appears to be near average.
Wind Discussion: Winds today through Friday will be mainly out of the northwest at 8 to 15 mph. Gusts to near 25 mph will be possible this afternoon through Saturday evening. Winds will be strongest along the Interstate 5 corridor. Winds Sunday and Monday will be generally less than 15 mph with periods of light winds during the night and morning hours.
Rain Discussion: Expect dry conditions.
