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.

SIGNS HAVE BEEN POSTED ALONG SEVERAL ACCESS AREAS ALONG THE  RIVER.

Here is my weekly weather quiz question for the last time. “What is a “Snow Advisory?” Here is the correct answer. A Snow Advisory: This product is issued by the National Weather Service when a low pressure system produces snow that may cause significant inconveniences, but do not meet warning criteria and if caution is not exercised could lead to life threatening situations. The advisory criteria varies from area to area. If the forecaster feels that it is warranted, he or she can issued it for amounts less than the minimum criteria. For example, it may be issued for the first snow of the season or when snow has not fallen in long while.

An Upper Level High Pressure Ridge takes over for clearing and some warming. The graphics for days 1-3  show a cold front sliding through Oregon between Tuesday and Wednesday. The graphics for days 3-7   Wednesday through Sunday show no frontal system pushing into the Pacific Northwest During the period.

An Upper Level Low Pressure Trough rotating offshore keeps the chance of rain around. The graphics for days 1-3  show a frontal system sliding into Oregon Saturday. The graphics for days 3-7   Monday through Friday show a frontal system to our northwest Tuesday and moving through Tuesday night and Wednesday.
