An upper air trough of low pressure (“U” shape) moved across Oregon. A cold front moved through the Pacific Northwest Saturday giving us more rain than expected. The airflow has straighten out quite a bit has decreased the cloud cover. That means a pretty good look , chilly though it may be in the dark of the early AM, at the moon that was the Full Pink Moon Sunday. Another day of sunshine looking a lot more like Spring. There will be more clouds with slight chances of getting wet Wednesday and Thursday, drying out Friday, but then back to wet as another strong frontal system for the weekend.
