in our 21st straight week of unemployment highs, there is some good news tonight. a look at the dangerous heat coming next week. the heat wave isn't waiting for the weekend. already parts of the bay area have triple digit temperatures and it is only going to get worse and more widespread. good evening. thanks for joining us. >> this is an unusual heat wave we're facing and it will reach dangerous levels as soon as tomorrow. a spare the air alert has been issued for tomorrow, warning of poor air quality levels from the combination of heat and car pollution. now this is the third spare the air alert issued for smog so far this year. that's fewer than usual because so many people are staying home during the pandemic.
