There will be a total lunar eclipse Monday night into Tuesday AM, but it will probably be too cloudy for us to see it. I’ll keep you updated. The Winter Solstice takes place at 3:38 PM Pacific Time Tuesday to officially begin Winter.

________________

The upper air flow (yellow jet stream and dark colors for winds) shows a  trough of low pressure swinging down from the Gulf of Alaska (“U” shape offshore) which is pushing lots of moisture and, for the most part, mild air  our way. We are still getting plenty of rain, in the Southern reaches of Western Oregon, from the storm that slid into Northern California. More storms will be coming at us next week including this frontal system that will come in for Christmas Eve. Not much of a chance of a “White Christmas” in the valleys because it will be too warm. Our best chance of valley snows usually comes in January and February.
