Wednesday brought similar weather to northern California that both Monday and Tuesday did... hazy sunshine and below-average temperatures. A trough of low pressure will bring a change to our weather the rest of the week. The trough which has been parked over the Pacific Northwest much of the week is finally beginning to move onshore. It will cause a wind shift which will bring more smoke from the Monument Fire and McFarland Fire into the valley and foothills. Tonight will get smokier for many areas, which will be more noticeable by morning. Lows will range from the 30s and 40s in the mountains to the 50s and 60s in the valley and foothills. Thursday will be smokier but warmer, with highs in the 80s and 90s for all areas.
As the trough passes northern California Friday, we can expect increasingly strong wind from the north Friday morning through Saturday morning. A Fire Weather Watch has been issued for the valley and foothills for that time period with gusty wind and much warmer and drier air. Friday will also be quite smoky for the valley and foothills. The wind will begin to weakend Saturday and the air will keep warming through Sunday. We shouldn't have as much smoke, but everyone will still be hazy to smoky for the foreseeable future. Another trough will begin to cool us during the first half of next week, and the breezes will get stronger. Valley lows will be mainly in the 60s through next week, while valley highs will be in the 90s and lower 100s.
