Only my way home from work I noticed some striking clouds in the sky. These are called altocumulus lenticular clouds.
According to pilotsfriend.com (http://www.pilotfriend.com/av_weather/meteo/clouds.htm), “This occurs due to a wave effect in the air flow. This wave effect normally develops as a result of a mountain range on windy days. The wave effect forces air to rise above the condensation level and hence allows cloud to form. Due to the rise and fall effect (peaks and troughs), the cloud may only exist in areas of peaks and therefore appear patchy. ”
While these normally happen on the lee side of a large mountain range, the coast range is the only range to the west. The coast range is not large at all. So, what could cause such a phenomenon? Perhaps with the air in front of an approaching system off the coast, moving at a relatively fast speed, is being “folded” as it slows down by friction over the not so smooth land mass. That faster air will eventually mix down to the ground later on to provide a bit of breezy conditions. We’ll see what happens.
In the meantime enjoy the sun. The rain returns again for the weekend.
