Advisories:

• A FREEZING FOG ADVISORY IS IN EFFECT UNTIL NOON TODAY FOR EASTERN CURRY COUNTY, JOSEPHINE COUNTY, AND JACKSON COUNTY.
• AN AIR STAGNATION ADVISORY IS IN EFFECT UNTIL 4 PM WEDNESDAY FOR CENTRAL DOUGLAS COUNTY, EASTERN CURRY COUNTY, JOSEPHINE COUNTY, THE EASTERN DOUGLAS COUNTY FOOTHILLS, JACKSON COUNTY, THE KLAMATH BASIN, NORTHERN AND EASTERN KLAMATH COUNTY, WESTERN, CENTRAL AND EASTERN LAKE COUNTY.
• A Blue-Green Algae warning  has been cancelled for Tenmile Lakes in Coos County, but continues for Fern Ridge Reservoir, Lost Creek Lake, and Willow Creek Reservoir (NE Oregon). 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.

The upper airflow has become a ridge of high pressure that will keep us milder for a while.   The snow is just about gone on the valley floor except where it was piled up. In the hills it is melting away slowly.
