Posted: Aug 22, 2018 6:35 AM

There is good news on the way in your Wednesday and extended forecast. A decent cooling trend is settling into Northern California today and the threat of mountain thunderstorms we had yesterday has now moved off to our East. Fire danger will not be as high given the lack of activity and the cooler temperatures should give a much needed reprieve to fire fighters across our region. Smoke will continue to have a big impact on air quality across Northern California, with most locations reporting moderate to unhealthy air quality this morning. Smoke impacts are expected to be similar to yesterday. Temperatures have dipped into the 50's to low 60's in the valley overnight, and into the 40's to 50's in the mountains this morning. Winds are starting out out of the East to around 5mph again this morning, but South winds to 10mph are expected from the late morning hours through this afternoon. Humidity is expected to stay slightly higher than yesterday, but could still fall into the 15 to 30 percent range this afternoon. High temperatures will end up in the low to mid 90's in the valley, and in the mid 80's to low 90's in the foothills and mountains.

Dry weather is expected through your upcoming weekend, but the cooling trend will also continue. Valley areas are projected to end up in the high 80's to low 90's on Thursday and will stay in that same range on Friday. More cooling is then in the forecast for your weekend. A cooler system will be dropping down from the North late this week, and is expected to continue to have cooling impacts through the start of next week. The current projections have the valley topping out in the low to mid 80's by Monday and staying in that range through the middle of next week.
