Of course that did not stop us in our compulsive pursuits of all things wind the last couple days which led us to one of our favorite applets ever. The San Francisco Bay Wind Pattern Streaklines on the SF Ports at the Us Geological Society shows animated wind patterns from the day you are looking at it. Of course it's more striking to watch the winder it is, but it's April so you should get a good show anytime.

Check out how the pacific winds stream into the mouth of the bay and actually accelerate to accommodate the pushing wind from behind. Then watch it curve north and south after it enter the bay. There a dang near 90 degree right turn that blows straight down to the South Bay and beyond. Or watch the coastal ranges and see how it is diverted and then shimmy over the ridges. Watch it get tangled in the 4,000 ft Grizzly peak east of silicon Valley. Look how Hillsdale and Burlingame are almost wind free.

While on this brisk note, local meteorologist, AA spotted frost just last Monday morning in the Woodside area. Where the heck is the windshield scraper?
