Finally it is hot is California. I have even heard folks in Santa Cruz complaining about the heat. Don't worry folks, the marine layer will be making a return as early as this Thursday evening.
A low pressure system is arching over a high into Alaska and then slipping down the coast via Vancouver and into the Northwest. The bottom of the low pressure system could get as far south as San Francisco. There it will sit for a few days, pumping fog on top of us, until it gets kicked west around next Tuesday evening.
During this period there is a slight chance of snow showers above 9000'. Better get those skis waxed. Also, there is a slight chance of actual showery weather (not just the heavy fog drizzle we have had all summer).
Heat has a good chance of returning mid next week. Our pattern is kind of an all or nothing situation. If a low pressure settles over the Pacific Northwest, we get a southwest breeze which pulls moisture from cool ocean waters on top of us. Read: cold foggy drizzle. When, and if, the low pressure gets bounced east, a ridge sets upon us and significantly raises heights. Read: hot, sunny and dry.
As we move into autumn, we see an increased chance of the second scenario. We have a chance at a beautiful autumn this year. Yay! And most of the long term forecast are showing a switch to a fall pattern with an increasingly active northern jet stream, some minor Gulf of Alaska storms and a big fat high pressure sitting on top of us.
Don't forget to water your plants, except for those you don't water. We have a fall tomato harvest in my backyard this year, but it is going off this week. I have also noticed some new growth on my Delicata and my summer squash, beans and cucumbers are looking so happy this week. OTOH, chard and bok choy look a little angry. Not sure yet how the peas feel about things.
