An upper level high pressure ridge ( Shaded “arch” shape) is sitting over us and will dry us out pretty much through New Year’s Day. A frontal system will break through as the ridge weakens on Friday giving us the chance of some precipitation. The ridge will regain strength and continue the dry weather through the weekend.

• A Blue-Green Algae warning  remains in effect for Lost Creek Lake, and Willow Creek Reservoir (NE Oregon). Water monitoring has confirmed the presence of blue-green algae that can produce toxins, state public health officials said. The algae levels are likely associated with dangerous cyanotoxin concentrations in the water that can be harmful to humans and animals. Swallowing or inhaling water droplets, as well as skin contact with water, should be avoided according to the authorities.

No winner this week. Here is my new weekly weather quiz question for the last time. What is the first rule when driving in fog? The correct answer is use only lo beans while driving through fog. High beams show you more fog and can blind oncoming traffic. I’ll have a new weekly weather quiz question for you 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.
