Advisories: A RED FLAG WARNING IS IN EFFECT UNTIL UNTIL 11 PM TONIGHT ALONG THE CASCADES AND THE FOOTHILLS OF NORTHWEST OREGON INCLUDING THE GIFFORD-PINCHOT NATIONAL FOREST, MT HOOD, AND THE WILLAMETTE NATIONAL FORESTS CONTINUING. A RED FLAG WARNING IS IN EFFECT UNTIL UNTIL 11 PM THURSDAY FOR THE BLUE MOUNTAINS OF NORTHEAST OREGON AND THE UMPQUA NATIONAL FOREST DUE TO LOW RELATIVE HUMIDITIES AND THE THREAT OF DRY THUNDERSTORMS PRODUCING LIGHTNING CAPABLE OF STARTING MORE WILDFIRES.

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 low (shaded “U” shape with blue arrows) is sliding  through northern California and Oregon bringing a chance of showers and isolated, mainly dry, thunderstorms today and Thursday over the mountains. The big problem with that is the development of dry thunderstorms, particularly over the mountains and foothills, that can produce more wildfires through lightning strikes.

Sorry, but no winner this week. Here is my weekly weather quiz question just one more time. How does the National Weather Service define “Yellow Snow?” And no, this is not a joke. Here is the correct answer. Yellow Snow is snow that is given a golden or yellow appearance by the presence in it of pine, cypress pollen, or anthropogenic material or animal-produced material (there’s what you thought was the only answer, right?).  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.

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 low (“U” shape with blue arrows) is sliding over the top of the high pressure ridge that has been over us. Next the low will roll to the east and northeast allowing the high pressure ridge will take over again for a while then a trough will move in through northern California. The cooler weather will make it more comfortable for fair goers at the Lane County Fair that ends today.

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. Today 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 over the rest of this weekend 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  continues through this evening at Willamette High School.
