Blowy and Snowy

It was such a sweet ridge of High pressure. Ellen and I had a nice evening ski on Wednesday under the waxing moon and no wind. But Low pressure along the California coast is in control this Friday morning. Light snow showers are possible today and Saturday, but the real story is the winds and wind chill. National Weather Service Doppler radar indicates wind gusts of 45 mph this Friday morning. By Saturday morning winds will be less SW 5-10 with gusts to 20-25 mph in the open areas. These winds will shift to South and increase towards sunset increasing to 10-15 with gusts 25-30mph in open areas. Mostly cloudy skies will block most, if not all, moonlight Saturday evening.
This morning's models remain in good agreement with previous runs. Snowfall starts early Sunday and becomes heavy at times during the day. Two models yield very different amounts: 2-4inches by noon in the GFS model vs 8-11inches in the WRF model. I am leaning towards the lower GFS while the current NWS forecast is holding on to the possibility of the higher WRF amounts.
So the bottom line is: Saturday and Saturday evening blowy and cold. Sunday blowy, cold and snowy. Temperatures will rise into the mid 20s both afternoons, but wind chills will make it feel colder.
More snow will fall into next week especially Monday.
