The weekend is wrapping up on a hot, smoky and fiery note around northern California, and 4 fires are currently burning around our region. A Dense Smoke Advisory has been issued for Lassen and Plumas counties through Monday morning due to smoke from the Hog Fire near Susanville. We can expect a mild night with a clear sky. Lows will range from the 40s and 50s in the mountains to the 60s and lower 70s in the foothills and valley. Monday will be a mostly sunny to sunny day with slightly cooler highs and isolated Sierra thunderstorms. Highs will range from the upper 80s to mid 100s.

A trough of low pressure will begin moving toward California on Tuesday, but won't pass overhead until Wednesday and Thursday. As it arrives, we'll have a gradual cooling of our hot summer weather and stronger breezes by midweek. The cooling won't be huge, however, and highs will remain near average for late July, even at their coolest. Our weather will remain seasonably hot through the late week and weekend with a few more breezes by next Sunday. Overnight lows will remain seasonably mild with 40s and 50s in the mountains and mainly 60s in the valleys. Highs will range from the 80s to near 100.
