Smoke continues to pour over much of northern California due to numerous fires across the region, and that smoky air won't be clearing soon. Red Flag Warnings continue through Thursday morning for much of our area. Tonight will be fairly clear of clouds, but there will still be areas of smoke. Lows will range from the 50s in the mountains to the 60s and 70s in the foothills and valley. Thursday will be a mostly sunny day, but many of us will still have a lot of smoke to deal with, and that will make our highs vary greatly from place to place. Most highs will range from the 80s in the mountains to the 90s in the foothills and the valley, but some lower 100s will still be possible where there is less smoke in the air.
The ridge of high pressure over the western United States will retreat further to the east on Thursday and Friday, and that combined with the smoke in the air will allow our highs to cool to more seasonable levels. The ridge will briefly push back toward the west this weekend, and our highs will once again climb to above average levels. Another trough of low pressure will push southward from the Pacific Northwest during the first half of next week. That will bring a few more clouds, stronger breezes and a modest cooling of our highs. Temperatures will stay above average, however. Highs this weekend and next week will range from the 80s and lower 90s in the mountains to the 90s and lower 100s in the foothills and valley.
