good tuesday morning. live look outside this morning, look at that. in dublin, as we get started with today. cars on the road, people moving about and we've got your news ready to go. >> that's right. >> before we get to the news got to get to that forecast for today. meteorologist kari hall has been tracking that. >> not bad. we've enjoyed some pretty nice weather here across the bay area and as we're starting out a live look in emeryville. our air quality today, it's starting to get slightly unhealthy for people who may be sensitive to some of the smoke, especially in santa clara valley, the coast and bay. elsewhere it is looking pretty good, staying below the 50 number that we use to measure how much smoke is in the air. as we look at our near surface smoke model it does show that in

san francisco, as well as parts of the east bay, later on this evening, this is tonight, we can see a little bit more of that smoke drifting in and it makes for some colorful sunsets. here's what's going on, new fires going, especially farther to the north, up around redding. the panther fire has really exploded and so some of that smoke is going to move into parts of the north bay, get drawn into the marine layer for the next couple days. we'll monitor air quality and the south bay, our high temperatures reaching up to 81 degrees in cupertino, 89 for a high in morgan hill and as you check out the seven-day forecast, stuff at the bottom of the screen looking steady. mid 60s for daly city and half moon bay as well as san francisco, mostly in the mid 60s this afternoon and still hot in clearlake and ukiah, reaching into the upper 90s. much more comfortable in santa

rosa with a high of 81 degrees today. overall, once again, our weather pattern not changing, but we'll see more fog and also some light showers just off the coast. for of the much bay area we'll get more of an ocean breeze and that's going to keep our temperatures fluctuating over the next few days with low 90s this afternoon and some mid 80s for the end of the week. and then you can see on friday we see those temperatures spike up to 93 degrees. overall it's going to be just slightly warmer compared to what we've seen. the coastal areas staying cool, still 60s continuing there. mike you're seeing unusual slowing in the tri-valley. >> weird pattern, the green over here for most of 608 and the group along the peninsula, changed now, okay, 84 we had sort of polka dots, yellow, green and orange, and now it's a little bit of slowing. it's so early, traffic is so light, one or two vehicles going more slowly would cause that and what looked like a big traffic

jam, not cleared. there you go, altamont pass, there's westbound slowing for 580, typical there, the bridges just fine getting down towards the east shorege. all lanes of highway 4 in this is after a shooting. chp says this happened about 8:00 last night. the section between summersville road and hill crest avenue was closed for hours due to that investigation. there's no word on the number of people injured or extent of their injuries. last week two people were shot along highway 4 east of port of chicago highway in concord. one woman died there. so far no word on arrests in either of those incidents. southern california conservative leaders plan to gather virtually to support efforts to recall governor newsom. it comes as ballots for the gubernatorial recall election will go out in two weeks. >> the candidates hoping to replace governor newsom will dwooebts later this week.

that makes this very unpredictable. >> reporter: a recent berkeley institute of governmental poll of likely voters show 50% want newsom to stay at the capitol and 47% want him out. a tight race. people can begin voting on when ballots are mailed in a matter of weeks. >> you don't have to vote yes to pick a candidate. you can vote no and pick one because the idea is, in the event that governor gavin newsom is recalled, who is there to replace him. that's why it's important for people to vote both in terms of the recall and the replacement candidate. >> reporter: republicans are expected to turn out in droves on september 14th. if democrats don't, that replacement vote will shape the future of california. jean elle, nbc bay area news. 4:53 right now. coming up next on "today in the bay," mystery solved at the olympics. >> the mascots, the kangaroo,
