A Swing in the Forecast; A Bit of Warming on the Way

A change of pace from the last set of forecast. The advertised storms for today, tomorrow and the weekend is a bust. Or, sort of. There is a storm sitting just off our coast on Thursday morning. And a fairly cold one to boot. But, it has temporarily removed itself from the jet stream and almost closed off. The result is that it is drifting south, instead of moving over land. Plenty of rain today and Friday, just north of the Bay Area, where the storm is sagging onshore.

As the storm slowly drifts southward, we will begin to see rain on Saturday. Eventually, this storm is to be picked back up by the jet and move eastward. Bad news for us snow hounds. If this system had moved over the area as previously forecast, it would have been a bulls eye for the Tahoe Basin. Instead, it will drop a lot of its moisture on the coastal ranges, and get a bit too far south, before moving over the Sierra. We can expect a few inches up in Tahoe on Saturday, but not much more. the good news is that freezing levels are expected to lower down to the lake, so we will get a bit more snow up on the peaks.

And that Big Halloween storm? This one looks like it will be mostly to our north in good La Nina style. Again, the areas north of the bay can expect plenty of rain, and some of that lingering into next week. We have a chance of rain down here, and snow in the hills, but expect a limited amount of precipitation. Alll in all, another wet and cool weekend is on tap. October has really delivered the weekend warrior with blah weather. OTOH, we have had a record breaking October for rain fall - which need I remind you is a very good thing. Has anyone noticed all the new growth out there. The hills will be green nice and early this year.

Now, for the good news. The cold air in Canada is headed east. A large trough is to form Monday on the east coast, pulling cold air south. The result for us is a large amplification (think sin wave, for you mathematically inclined folk) and very warm weather. Highs in the 80s in the Bay Area the first half of next week. Get out and enjoy it while you can. The long term models are suggesting another system may come into the region sometime between Thursday and the first weekend of November. To early to tell if this one will slide by to our north or hit us squarely. But, it does look like the Pacific storm door will open after a few nice days of living under a blocking high pressure.

Surfers, rejoice - or hunker down. A very big swell is expected coming soon. First, for the next few days, we have S/SE winds preceding the rain. Swell should jump up again on Friday into Saturday. Things should settle down, until Tuesday. On Sunday/Monday a large storm is projected east of British Columbia. This baby could send us 20 foot long period swells beginning sometime on Tuesday. Be careful if you venture out. And for the non-surfers; stay well clear of the water. this is the type of event that has the potential to sweep on lookers off cliffs and rocks, and to a very non fun experience. California experience several deaths of this type annually.

Our Fava Beans are breaking ground and looking happy. As is the chard and choy. Many of our summer plants are done, but a few squash plants are holding on. Get your garlic cloves in the ground over the next four weeks. Now is still a good time to put in some winter seedlings, especially with a few warm days expected next week. That ground is still wet, but with the chill of the past few mornings, I don't expect much of that warmth to still be there. Persimmons and Pineapple Guavas are showing up in the markets. Apples and Tomatoes are still around. As are a few stone fruit. This has got to be the best time of year n these parts. Color abounds.
