Here is my new weekly weather quiz question. What is the “Solar Wind?”
____________
An Upper Level High Pressure Ridge takes over for clearing and some warming, but a cold front brings one day of cooling. The graphics for days 1-3 show a cold front sliding through Oregon between today and Tuesday , but it will only lower temperatures a bit. The graphics for days 3-7 Thursday through Monday show no frontal systems pushing into the Pacific Northwest during the period except for a cold front to our northwest next Monday.
