Smoke and poor air quality are now the biggest short term issues for the weather of northern California. Not only are we being covered by smoke from the Bear Fire, but smoke from other fires in California and Oregon is moving over our area, too. Tonight will be fairly smoky for most areas, and a Dense Smoke Advisory is in effect for Lassen and Plumas counties through Friday afternoon. Lows will range from the 30s and 40s in the mountains to the 50s and 60s in the foothills and valley. Friday will more than likely be a smoky, hazy day for most areas, but there will be a lot of sunshine above and away from the smoke. Highs will be mainly in the 80s due to the smoke, with some lower 90s possible.
A ridge of high pressure is still in control of our weather at this time, but changes are coming to our weather pattern fairly soon. Saturday will be a little brighter and warmer day, but we will still struggle with smoke. Beginning on Sunday a trough of low pressure will move over the Pacific Northwest and northern California, ushering in breezy weather Sunday and Monday, followed by stronger wind next Tuesday and Wednesday. The wind could raise our fire danger, but on the positive side we can also expect cooler weather and even a chance for light rain showers through next Thursday. Highs will begin cooling from the 80s and 90s this weekend for most areas down to the 70s and 80s much of next week.
