The September weather was exciting to say the least! We had a record heat wave, remnants of tropical cyclones, and now we are in a normal fall weather pattern. But wait, could we see a winter storm system this weekend? Yes, yes we could. The rest of the week and the weekend will be characterized by partly cloudy, slightly cool and windy (even windy) conditions. A storm system from Alaska, fed by moisture from a western Pacific typhoon (did that catch your eye?) will come to the coast on Sunday, likely bringing rain to parts of State. There is some agreement that it will more directly target central California, bringing rain and some wind. Locally, at this point, I would expect rain from Sunday to Monday. The exact timing and extent are a little uncertain, but it’s possible we could see up to an inch in the Coast Mountains. Systems like this are not uncommon in the fall, but this one is about a month ahead. Stay tuned for forecast updates.
