The area of low pressure that brought thunderstorms to Burney and Big Bar on Monday has continued its course down the coast and is now just off the coast of the Bay Area. Even though we are still being caught up in the flow of this area of low pressure all we’re seeing are a few clouds. This low will continue to move down the coast and should be to the east of Southern California by Friday.
Another trough of low pressure will approach from the Gulf of Alaska by Friday and into the weekend but it looks like the bulk of the energy will be to our north. The main impact will be slightly cooler temperatures on Friday and Saturday with partly to mostly cloudy skies. At this point I’m leaving any mention of rain out of the forecast, even in the mountains.
It looks like a zonal flow pattern (fast flow of the jet stream from west to east) will set itself up on Sunday and last into next week. There may be a series of weak disturbances that will move through this flow and bring us some clouds but it’s not looking all that promising for rain just yet.
