June 10, 2018 – NorCal is now on the backside of the sharp trough presently lifting northeast through the PacNW with a few high clouds moving across the region from the west.
Winds are much lighter early this morning. Current temperatures are considerably cooler compared to 24 hours ago (10-20 degrees in many spots) and range from the 30s in the mountain valleys to the upper 40s and 50sacross the Central Valley.
The trough will shift further east today replaced by flat ridging from the eastern Pacific. This will lead to a warming and drying trend this week.
Breezy north winds are expected today and Monday through the Central Valley. By Tuesday, highs will be well above average with warmest readings around the century mark in the Central Valley.
Extended discussion (Thursday through Sunday)
Several upper lows moves through PacNW towards the end of the week into the weekend with associated upper troughing over NorCal. This will result in minor cooling but temperatures remaining above normal Thursday through Sunday with dry weather.
