As predicted upper level high pressure (“Arch” shape in blue arrows) took over warming us up. We’re on our roller coaster again with heating yet today followed by cooling over the weekend as a cold front slides through on Sunday. We could see more record highs today. Thursday Eugene tied the record of 97 set in 2010. For today the record is 96 and we should surpass that. North Bend set a record high yesterday of 91 which heartily beat the old record of 79 set in 1944. They should be cooler at the coast.

• A health advisory remains in effect for the Ross Island Lagoon and the mouth of the lagoon as it connects to the Holgate Channel. Ross Island Lagoon is located about one river mile south of downtown Portland in Multnomah County. The advisory is being issued due to visual confirmation of a blue-green algae bloom in the lagoon. Oregon Public Health officials advise people to avoid swallowing or inhaling water droplets as a result of swimming or high-speed water activities, such as water skiing and power boating in areas where blooms are identified.

We’re on our roller coaster again with cooling now followed by heating then followed by cooling over the weekend. A cold front will slide through the Pacific Northwest to bring us some cooler air.

Advisories:

• A HEAT ADVISORY IS IN EFFECT FROM 2 PM THURSDAY UNTIL 8 PM FRIDAY FOR THE COAST RANGE OF NORTHWEST OREGON, THE CENTRAL COAST RANGE OF WESTERN OREGON, THE GREATER PORTLAND METRO AREA, THE CENTRAL WILLAMETTE VALLEY, THE SOUTH WILLAMETTE VALLEY, THE WESTERN COLUMBIA RIVER GORGE, THE CENTRAL WILLAMETTE GORGE THE CASCADE FOOTHILLS IN LANE COUNTY AND THE UPPER HOOD RIVER VALLEY.
• A health advisory remains in effect for the Ross Island Lagoon and the mouth of the lagoon as it connects to the Holgate Channel. Ross Island Lagoon is located about one river mile south of downtown Portland in Multnomah County. The advisory is being issued due to visual confirmation of a blue-green algae bloom in the lagoon. Oregon Public Health officials advise people to avoid swallowing or inhaling water droplets as a result of swimming or high-speed water activities, such as water skiing and power boating in areas where blooms are identified.
• A health advisory remains in effect for Agency Lake. Agency Lake is located just north of Upper Klamath Lake near Klamath Falls along Highway 97 in Klamath County. Water monitoring on the lake has confirmed the presence of high levels of blue-green algae and associated toxins that can be harmful to people and animals. Swallowing water while swimming or inhaling water droplets as a result of high-speed water activities, such as water skiing and power boating, should be avoided in areas where blooms are identified. Although toxins are not absorbed through the skin, contact with cells from a bloom can cause skin irritation and a red, puffy rash in individuals with skin sensitivities, or those who develop rashes easily.
• 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. Although toxins are not absorbed through the skin, people who have skin sensitivities may experience a puffy, red rash at the affected area.

Here is my weekly weather quiz question for the last time. What is a “Theodolite?” Here is the correct answer. A Theodolite is an instrument used in surveying to measure horizontal and vertical angles with a small telescope that can move in the horizontal and vertical planes. It used to track the movements of either a ceiling balloon or a radiosonde. 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.
