Today poor air quality continues as light winds keep the smoke settled in the area. The heat has also been evident today in the north valley whereas as the central valley has remained cooler thanks to more smoke cover.
Smoke will continue to blanket the region over the next few days. This is because the forcast is calling for more light winds. Only stronger winds will be able to mixing the smoke out of our air at the surface.
We will remain in the 90s through Tuesday as a slowing weakening ridge of high presure remains over us. This will also keep us sunny and dry.
The ridge of high pressure leaves on Wednesday allowing most to keep highs only in the upper-80s on Wednesday.
By Thursday a trough of low-pressure will be closer to our region, just off the Pacific Coast. This will bring valley highs on Friday into the 70s.
Rain chances are now in the forecast for Friday & Saturday. The GFS & Euro models (two reliable long-term weather models) show different rain amounts. Many ensemble models and other long-term models also indicate a chance of rain. Exact amounts and times will become more clear as the event draws near. A trough of low pressure will swing down from the Gulf of Alaska while Hurricane Marie in the Pacific weakens and travels west, then north. Post-tropical Marie will then feed extra moisture into the low-pressure system making landfall on the west coast. This increases the chances of rain. Even snow could be possible at the highest elevations along with highs in the low-70s and maybe even upper-60s in the valley.
