Slightly warmer temperatures and all around mild conditions are expected for your Tuesday across Northern California. The system that brought the nice cooling trend yesterday has now tracked off to the East and high pressure will be building back up in it's wake. Temperatures will be 3 to 5 degrees warmer for this afternoon, but will still be around or below average for this time of year. Valley areas have dipped into the 50's to low 60's overnight, and mountain areas are starting out in the low to mid 40's this morning. Winds are starting out of the Northeast to around 10mph this morning, but will shift to become out of the South to 10mph this afternoon. High temperatures are projected to top out in the 88 to 94 degree range in the valley this afternoon, while most mountain areas end up in the mid to high 80's later today. Smoke from the current fires will continue to impact air quality, but the majority of our region is showing air quality in the moderate range again to start our Tuesday.
Another cooler system will be passing through to our North for the middle of this week, and that will result in cooler temperatures ahead for Wednesday and Thursday. Most valley areas are expected to top out in the mid to high 80's for the middle of the week, before a warming trend returns on Friday. High temperatures will end up back in the high 80's to low 90's in the valley on Friday and will then be in the low to mid 90's this weekend. There may be another subtle cooling trend on the way for your labor day, but that is not expected to bring us much of a change compared to Sunday. Dry weather will persist through your extended forecast and temperatures will be staying on the mild side for the next week.
