Park rangers say be very careful. Thats the latest from daly city, juliette goodrich, kpix5. The other big story heading into a night of subfreezing temperatures, right now we have hail falling in the east bay in addition to the wind you saw. This is a mix of rain and hail in berkeley. Look at this. So cold this morning we saw some snow flurries in the santa cruz mountains. The cold weather is a major concern, of course, in wine country. Kpix5s Katie Nielsen explains growers are racing to protect their vineyards. Reporter they are. Were here in downtown napa off main street. People are walking by bundled up a lot warmer than normal for this time of year because the lows tonight could dip down about 27 degrees. Thats definitely cold enough to freeze plants and also those grapevines. Frost blankets are hard to come by these days in napa, none left at ace hardware. Sold out of that over the weekend. Well have that back on the shelf today. Reporter people are getting creative hoping plastic sheeting or an old bath towel will protect their plants. It was 28 last night at my place. Live out in the country. Reporter another creative way to combat the cold . Flaming hot cheetos, well, kind of. Theyre just hot and makes my mouth feel warm instead of cold. Reporter maybe not the best idea, but its got to be better than this. Once it got warm enough to put shorts on, i dont like going backwards. Reporter worried about frostbite . No the not even close. Vines on the other hand, a little, but not for me. Reporter thats the concern here tonight, the vines. Thanks to the warm weather some of the chardonnay grapes already have vines and leaves. The buds think its springtime, time to wake up. Reporter but those buds make the vines more susceptible to damage during tonights cold snap. Once it gets so cold were really at the whims of mother nature. Reporter the low only hit around 30 degrees last night, but the air kept moving meaning no frost and no freezing vines. Tonight could be a different story. So here theyll turn on the fans around 1 a. M. Keeping the air moving, it keeps that cold air and potentially ice from forming on this little bud. Reporter now aside from turning on the fans, there really isnt a lot that the wineries can do to protect those grapes. Coming up tonight at 6 00 well tell you about the animals that will be most impacted by tonights below freezing temperatures. Live in napa, Katie Nielsen, kpix5. Take a look at this.

San Francisco Police dont have tasers, but mayoral candidate london breed said that they should. Kpix5s phil matier said its now an election issue and breeds decision sets her apart from some of her rivals. Phil . Reporter thats right. Its almost been an eightyear tug of war in San Francisco over the debate. Should police use these shock guns instead of their own weapons . In cases it might save lives. In other cases it might save harm. So we asked breed, president of the board of supervisors and now mayoral candidate, what made her go public with support for the stun guns . I hate guns. Guns have destroyed the lives of so many in my community. Reporter supporting tasers, however, immediately put breed at odds with her progressive rivals in june race like former state senator mark leno. Tasers yes or no and why . No until we implement all of the reforms the department of justice put before the san Francisco Police department. Reporter candidate and supervisor jane kim also said no to tasers for now saying that instead we need to deescalate situations safely. This keeps everyone safer. On the other hand, theres former supervisor Angela Alioto who has long supported giving cops tasers. Theres a total lack of common sense in this city when it comes to certain things. Again, why not have a taser when it wont kill somebody . Why not . Reporter at the same time alioto noted breed did not publicly come out for tasers. Tasers until she was running for mayor. She has been against it for years. Wonders never cease. Reporter you havent always been an advocate for tasers. Ive been an advocate for Police Reform and pushing to change whats happening in the department. Reporter recent polls show seven of 10 voters back police using tasers in San Francisco, especially on the citys more moderate west side. The loudest at city hall seem to be the progressive activists, but at the end of the day its those absentee voters, homeowners and ethnic communities in vote. I think its communities that vote. I think its a distraction because the thing im hearing about from everyone right now is about car breakins. Reporter a measure will be on the june ballot right when those candidates run for mayor and at 6 00 well look at the politics that may be at play here as well. In San Francisco, phil matier, kpix5.

The first superhero movie with an all black cast opened at the box office this weekend. Cbs this mornings gayle king asked the films director and bay area native ryan coogler his thoughts about seeing the superheroes in black panther. What i noticed was none of their world looked like my world, my world growing up in the east bay area in oakland. You know, my friends, my family, everybody was black. The movie brought in roughly 192 million. Thats the highest debut ever for a film opening in february and the fifth highest debut of all time. 1 nther is the l cbs reporter Jericka Duncan has more on this cultural phenomenon. Reporter black panther is the latest in a long line of marvel comic book superheroes turned movie stars. Fantastic. Easily the best marvel movie. I was just so looking forward to this movie since the day the trailer came out. Reporter typically movie superheroes are white. So black panther has appealed to comic book fans as well as a more general black audience. The film holds special meaning for many long time fans and particularly for arielle johnson. I think i might have to be carried out. Reporter johnson is one of the first black women to open a comic bookstore on the east coast. She opened amalgum comics and coffeehouse in philadelphia a little over two years ago. Shes waited for a film like black panther since she fell in love with comic books as a girl. I was about 11 or so that i actually was introduced to the xmen and the thing that really grabbed me was storm. Up until that point i hadnt ever seen a black woman superhero. Theres something clicks when you start to see yourself, you know, reflected back at you. Reporter this isnt the first time a black comic book hero was the lead role in a film. The threepart blade series beginning in the late 90s starred Wesley Snipes as a vampire hunter. But when you think about the people who were around blade in that movie, it wasnt like an all black cast. I think the thing about black panther, it is essentially a black movie, you know, and like in hollywood terms, but usually when the movie is a black movie, white audiences dont see it. Reporter but thats not the case with black panther. The box office tells the tale of the films success. This weekend it brought in nearly 200 million and it set the record for a live action superhero movie on rotten tomato with a score of 97 . For cbs, Jericka Duncan, philadelphia.

So its been a year of extremes and that will continue now with temperatures having changed dramatically in the past couple of days. Right now were looking to buildups over the east bay range and temperatures are within a couple of degrees of 50. So what a difference a few days make. Were in the low 70s on saturday. Tonight it will be cold, into the mid20s inland, around the bay in the mid30s. Heres how it looks off the west coast. Theres high pressure, but its directing all the cold air from the gulf. It will be unsettled and chilly through tomorrow and then the high nudges back in. By the weekend well get back to the near 60degree range.

The coldest night tonight, the lows in the 20degree range, only slight warming and a little less windy tomorrow. It will be back into the 60 degree range by friday. Overnight tonight well be about 10 degrees below average. For the bay area, San Francisco down to 38 and san jose 31 and oakland 36 degrees. Again these are lows for tonight. Its freezing in sunnyvale, 30 for santa clara, 32 for Mountain View and 31 in san jose. Over in the east bay the skys clearing is not good news for the temperatures. Theyll plummet into the low 30s in the east bay after sunset, 27 for santa rosa tonight, 27 in petaluma, 30 for napa, 29 degrees in sonoma. So its late february par for the course. Well usually get a cold snap this time of year and they certainly will up in ukiah, lake port and clearlake. Extended forecast shows high clouds tomorrow and temperatures in the low to mid 50s, a notch warmer than today. In the extended forecast well look for 50s all the way through the weekend. By the time we get to saturday and sunday it will absolutely skyrocket back to 60 degrees, back where we belong to quote one of the famous meteorologists, cant quite remember who.
