you wear? ahead, a new eye-opening study on masks that could have you rethinking the kind you use. also not much social distancing or mask-wearing. the crowded concert and the bay area band's comments making headlines. i'm chief meteorologist jeff ranieri. i'll show you how widespread the fog is for tomorrow morning and the big heat on the way in just a few minutes.

a san jose musician is catching a lot of grief on social media. last night at a crowded concert in south dakota, smash mouth lead singer steve harwell started the set by shouting "f that covid stuff." we cleaned up the language a bit. critics tweeted back a famous line from the hit all-star. it says, i ain't the sharpest tool in the shed. masks were only suggested. as s, not many people

seem to be wearing them, and social distancing wasn't quite there either. but smash mouth says safety precautions were taken. the band's manager telling billboard, quote, the promoter did a fantastic job with their covid protocol. they had a very strict social distancing and mask policy in place for all workers. the audience members were mostly bikers who converge annually on the town of sturgis for a massive motorcycle rally. it's expected to draw up to a quarter of a million riders, likely the nation's biggest gathering since the pandemic began. well, it's no longer to mask or not to mask. it's whether all masks are created equal. it turns out they're not. nbc bay area's cheryl hurd shows us a new study that looks at which masks work and which ones really don't offer you that much protection. >> reporter: they come in all shapes, sizes, and colors. and in california, everyone is required to wear one. >> i think we should all just wear it. what's -- whether you believe in it or not, just wear it.

bottom, so when you breathe, everything is collecting at the bottom of a bandanna. it passes down into your neck and onto your chest. that's not really a good idea. >> reporter: duke university researchers say they conducted this study to help people better understand the options they have to protect themselves during this pandemic. >> we want to bind together as a society to rid ourselves of this monster. >> reporter: cheryl hurd, nbc bay area news. not what we want to hear. as school is starting back up, more children are getting infected with covid-19. that's according to the american academy of pediatrics. siept scientists say there's been a 40% increase in pediatric cases. children now make up nearly 9% of all covid cases. san francisco streets got a new mural today. volunteers of all ages and races were in the tenderloin to help paint the words "housing black" on golden gate avenue. it was painted on the concrete with the hopes that it would spur some concrete solutions in

a city that has long been accused of pushing out its black residents. it's estimated blacks make up only about 5% of the population in the city and yet 40% of its homeless population. >> it's a very severe circumstance that we're dealing with, and this is probably the best way to get it in the concrete, in the street. >> supervisor matt haney, you see there, says he'll introduce a resolution tomorrow that supports today's message that more funding is needed for programs that help blacks get into housing. a setback for uber and lyft. a san francisco judge ruled that ride share drivers should issue an injunction that lasts ten days, which forces the companies to classify their drivers as employees and then grant them benefits. uber and lyft say they will appeal and uber adds it doesn't anticipate any immediate change to its business. lyft says drivers don't want to be employees, and it will continue to fight for their

independence. california's attorney general and three cities attorney including san francisco's contend under the new law, ab-5, uber and lyft don't have a choice. get ready to look up. meteors will be lighting up the bay area sky. the annual perseid meteor shower. the debris crashes into the earth's atmosphere creating bright streaks in the sky as they burn up. perseid lasts for week but the peak of the shower is tomorrow night and then wednesday night. we also know that a certain someone probably has his telescope -- >> that guy. >> -- ready to go. >> take it away, jeff. >> i just hope the fog -- the fog is going to be kind of 50/50 for me on if that's going to be getting in the way, the way things are positioned right now. that's going to be a big problem for a lot of us is the clouds and that fog. let's give you a look right now. if you're going to be up early, 2:00 a.m. to about 4:30 in the

morning is really some of the best time to get a view of that. you can see in this top-down view of the cloud cover, down here over the south bay, you'd have the best chance of potentially seeing something, again, tomorrow morning, also into wednesday morning. otherwise we have those low clouds in the east bay, the north bay, and also san francisco to start right there at 7:30 in the morning. now, 95% of that clears back as we head through 11:00 in the morning. that will set us up with a lot of sunshine away from the coast. so that means we're going to start off with some 50s again tomorrow. kind of a chilly start if you're up early. 59 for the south bay. tri-valley at 57. i have you down to 54 here in san francisco. some of that fog, also spotty drizzle, and 255 55 in the nort bay. tomorrow, we know it's back to school, albeit back to skoal at home. for the parents looking to send their kids outside for some recess, anytime between 11:00 a.m. to 3:00 p.m. is going to be
