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.

Advisories: There is a Blue-Green Algae warning that continues for Dexter Reservoir and Dorena Reservoir has just been added to the list. 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.

An upper level high pressure ridge  (“Arch” shape with blue arrows) has covered the Pacific Northwest for a while giving us offshore airflow which has kept us heated up. An upper level low (“U” shape with blue arrows) is sliding down from the Gulf of Alaska. By Saturday it will push over the ridge, then move to the northeast. A weak cold front (position shown is Monday well past us) will slowly move down from the northwest Saturday and that will mean temperatures will be cooling to the more comfortable mid to low 80s as the front slowly moves across Oregon. The slow cooling will make it more comfortable for fair goers at the Lane County Fair that continues through Sunday and the Relay For Life that began this evening and continues through Saturday evening at Willamette High School.
