A large fire in southern Oregon has made things hazy in Norther California. North winds have brought this smoke to our Northern counties which are seeing air quality issues. Unhealthy air quality for sensitive groups can be seen in parts of Siskiyou, Shasta, Trinity and Modoc counties. The good news is the winds have shifted and picked up. This is causing a lot of the smoke to disperse and move out of the valley this evening, however our Northern most regions could still be affected. The winds calm down tonight which will unfortunately lead to a retun to smoky conditions.
A heat advisory is also in effect for Valley locations until 11pm tonight. Triple digits have been seen across the valley but temperatures look to dramatically decrease into tomorrow. Tomorrow highs will be back to normal in the valley and remain that way through much of the week. This is because a trough of low pressure to our North will cause the high pressure in our area (that is keeping us hot) to back off to the East.
A return to triple digits is possible next weekend.
