An upper level high pressure ridge (“Arch” shape in blue arrows) is setting itself up off the Pacific Coast to bring us sunshine and much warmer temperatures. A frontal system will be pushing through Oregon by next Sunday. It looks like another frontal system will be heading our way next Tuesday. You may just want to check out this year’s Perseid Meteor Shower which peaks from tomorrow Thursday August 10th through Sunday August 13th. It is predicted that you could see up to 200 “shooting stars” per hour from debris from the comet Swift-Tuttle. Best viewing is late at night to before sunrise. Make sure you are out far enough away from the city lights so the sky looks darker a and the meteorites will be more easily seen.

Advisories:

• A Blue-Green Algae health advisory is in effect for Odell Lake in Lane County. Water testing has confirmed the presence of blue-green algae and the toxins they produce. People should avoid swallowing water while swimming or inhaling water droplets as a result of high-speed water activities, such as water skiing or power boating, in areas where blooms are identified. Although toxins are not absorbed through the skin, people who have skin sensitivities may experience a puffy, red rash at the affected area.
• A Blue-Green Algae health advisory remains in effect for Howard Bay (sometimes called Howards Bay or Howard’s Bay) in Upper Klamath Lake ONLY. People should avoid swallowing water while swimming or inhaling water droplets as a result of high-speed water activities, such as water skiing or power boating, in areas where blooms are identified.

Here is my weekly weather quiz question for the last time. What is a “Symmetric Double Eye?”  Here is the correct answer. A Symmetric Double Eye is a concentrated ring of convection that develops outside the eye wall in symmetric, mature hurricanes. The ring then propagates inward and leads to a double-eye. Eventually, the inner eye wall dissipates while the outer intensifies and moves inward. 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. Good luck.

Advisories:

• A Blue-Green Algae health advisory is in effect for Odell Lake in Lane County. Water testing has confirmed the presence of blue-green algae and the toxins they produce. People should avoid swallowing water while swimming or inhaling water droplets as a result of high-speed water activities, such as water skiing or power boating, in areas where blooms are identified. Although toxins are not absorbed through the skin, people who have skin sensitivities may experience a puffy, red rash at the affected area.
• A Blue-Green Algae health advisory remains in effect for Howard Bay (sometimes called Howards Bay or Howard’s Bay) in Upper Klamath Lake ONLY. People should avoid swallowing water while swimming or inhaling water droplets as a result of high-speed water activities, such as water skiing or power boating, in areas where blooms are identified.
