Another upper level low is moving through the Pacific Northwest. A powerful frontal system slammed into Oregon today bringing rain and high winds. There was significant tree and power line damage in scattered areas. The next storm is on the way (you can see it connected to today’s storm) so don’t get too comfortable. Local skiers are celebrating. The mountains have a lot of new snow and Willamette Pass, Hoodoo and Mt. Ashland are all open, with night skiing starting today at Hoodoo. Check their websites for updates.

Here is my weekly weather quiz question for the last time. What is an “ Easterly Wave?” Here is the correct answer. An Easterly Wave is a low level disturbance of tropical origins. Easterly waves can develop into tropical cyclones. However, tropical cyclone development is not required in order for these systems to produce significant amounts of rainfall. The easterly waves are primarily a summer phenomenon. I’ll have a new weekly weather quiz question for you starting Monday. Please remember to post your answer as a comment by clicking on “no comments /comments” in the upper right hand portion of this page under the caption, then add your comment. The first person to post the correct answer will win a week of free personalized weather forecasts tailored to your needs. The answer has to be a comment to win. An email answer will not count. Good luck.

Another upper level low is moving through the Pacific Northwest. One frontal system pushed in bringing cooler air in behind its cold front and now another warm front followed by a cold front is next in line.

Ashland are all open, with night skiing starting Monday December 21st at Hoodoo. Check their websites for updates.

Here is my weekly weather quiz question for the last time. What is an “ Easterly Wave?” Here is the correct answer. An Easterly Wave is a low level disturbance of tropical origins. Easterly waves can develop into tropical cyclones. However, tropical cyclone development is not required in order for these systems to produce significant amounts of rainfall. The easterly waves are primarily a summer phenomenon. I’ll have a new weekly weather quiz question for you starting Monday. Please remember to post your answer as a comment by clicking on “no comments /comments” in the upper right hand portion of this page under the caption, then add your comment. The first person to post the correct answer will win a week of free personalized weather forecasts tailored to your needs. The answer has to be a comment to win. An email answer will not count. Good luck.

Another upper level low is moving through the Pacific Northwest. One frontal system pushed in bringing cooler air in behind its cold front and now another warm front followed by a cold front is next in line. Local skiers are celebrating. The mountains have a lot of new snow and Willamette Pass, Hoodoo and Mt. Ashland are all open, with night skiing starting Monday December 21st at Hoodoo. Check their websites for updates.

Here is my weekly weather quiz question for the last time. What is an “ Easterly Wave?” Here is the correct answer. An Easterly Wave is a low level disturbance of tropical origins. Easterly waves can develop into tropical cyclones. However, tropical cyclone development is not required in order for these systems to produce significant amounts of rainfall. The easterly waves are primarily a summer phenomenon. I’ll have a new weekly weather quiz question for you starting Monday. Please remember to post your answer as a comment by clicking on “no comments /comments” in the upper right hand portion of this page under the caption, then add your comment. The first person to post the correct answer will win a week of free personalized weather forecasts tailored to your needs. The answer has to be a comment to win. An email answer will not count. Good luck.

Another upper level low is moving through the Pacific Northwest. A frontal system pushed in bringing cooler air in behind its cold front. Local skiers should be celebrating. The mountains have a lot of new snow and Mt. Ashland has already started their season. Willamette Pass and Hoodoo opened officially today with night skiing starting Monday December 21st at Hoodoo. Check their websites for updates.
