You may have noticed the warning in today’s forecast saying:

“With strong NNW winds at the 975 mb. level at ≈ 1,000 ft. the prevailing surface winds may be diverted at times at some sites.
Note: NNW winds aloft may make the winds UP AND DOWN at times especially Pt. Isabel and maybe Coyote and 3rd. Ave.”

Those winds aloft impacted many sites and you can see in these wind graphs. Notice how the Bodega 449MHz vertical profiler picked up t those winds BEFORE they rippled over the coast range and impacted the surface winds.

And, yea as I warned they spoiled the building Ocean Beach winds.
