Advisories: There is a Blue Green Algae warning that continues for Dexter Reservoir. 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) still covers the Pacific Northwest. It’s called a “Rex” block because of the way it blocks storms from coming through it. That means more sunshine but temperatures will start to cool off a bit. An upper level low (shaded “U” shape with blue arrows) will slide down from the Gulf of Alaska and a cold front will slowly move down from the northwest between Thursday and Friday and that will mean temperatures cooling to the more comfortable mid to low 80s as the front slowly moves across Oregon.
