Southwest airflow from the Jet Stream (Shaded “Arch” shape with blue arrows aimed Southwest to Northeast) will keep warm air headed our way. The graphics for days 1-3 show a surface low moving inland  through Washington only keeping us a bit cooler. The graphics for days 3-7 show a frontal system trying to make an impact on us Monday through Wednesday, but not succeeding.

Advisories:

•  The Oregon Health Authority has updated the health advisory issued June 30 for Lake Billy Chinook, located about 12 miles west of Madras in Jefferson County. The update lifts the advisory on those areas of the Deschutes and Crooked River of Lake Billy Chinook arms affected by the advisory, and confines the advisory on the Metolius Arm to Perry South Cove. Water monitoring has confirmed that the level of blue-green algae toxins are below guideline values for human exposure. However, OHA recommends that people remain cautious when using the lake, particularly with pets because toxins are still well above the very low exposure levels established for dogs.
• A Permanent Health Advisory remains in effect for the South Umpqua River and Lawson Bar. Pools in the bedrock along the rivers edge are known to develop Blue-green Algae (cyanobacterial) blooms that can be harmful to pets and people if accidental ingestion occurs. Signs have been posted along several access areas along the river.

Here is my weekly weather quiz question for the last time. What is a “Barber Pole?” (In Meteorology) Here is the correct answer. A Barber Pole [Slang], is a thunderstorm updraft with a visual appearance including cloud striations that are curved in a manner similar to the stripes of a barber pole. The structure typically is most pronounced on the leading edge of the updraft, while drier air from the rear flank downdraft often erodes the clouds on the trailing side of the updraft. I will have  new weekly weather quiz question for you starting Monday. The first person to post the correct answer as a comment on this page will win a week of free personalized weather forecasts tailored to your needs.  Good luck.

An Upper Level High Pressure Ridge (Shaded “Arch” shape with blue arrows) is moving to the east and n Upper Level Low Pressure Trough (Shaded “U” shape with blue arrows) to our north are going to keep us in relatively normal temperatures for the season with minor fluctuation up and down.  The graphics for days 3-7 show the frontal systems that attempt to move into the Pacific Northwest Thursday through Monday of next week bringing a slight chance of light rain or drizzle Wednesday and Thursday.

Advisories:

•  A Health Advisory continues for Lake Billy Chinook, located 12 miles west of Madras in Jefferson County. Water monitoring has has confirmed the presence of Blue-green Algae and the toxins they produce. These toxin concentrations ca be harmful to humans and animals. 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. Drinking water directly from these areas of Lake Billy Chinook at this time is especially dangerous. Oregon public health officials advise campers and other recreational visitors that toxins cannot be removed by boiling, filtering or treating water with camping-style filters.
• A Permanent Health Advisory remains in effect for the South Umpqua River and Lawson Bar. Pools in the bedrock along the rivers edge are known to develop Blue-green Algae (cyanobacterial) blooms that can be harmful to pets and people if accidental ingestion occurs. Signs have been posted along several access areas along the river.
