This blog will be issued every Monday, Wednesday, and Saturday morning and updated if the weather is changing or critical or interesting weather events are occurring.
Two different low pressure areas will move through Northern California during the next several days. The first system is to our west and the second is currently in the Gulf of Alaska (see satellite picture below). The first system will spread rain over the area today through Thursday afternoon. This is a warm system and snow levels will be 6000 feet or higher. There will be a short break Thursday afternoon through early Friday.
Friday the colder system will be along the coast and will remain there through Saturday (see map below). The first shot of precipitation from this system will move through Friday. This will be a colder storm and snow levels will be 3000 feet north and slightly higher south. Gusty south winds will precede this storm.
Another brief break late Friday and early Saturday and then the next band of rain moves through. Snow levels will be 2000 feet north and 3000 feet south. The precipitation will end early Sunday with decreasing clouds Sunday afternoon.
High pressure will be along the coast by Monday should hold there for at least 5 to 7 days. This means a return to spring weather next week.
