one of the busiest stretches of freeway in the united states is shut down and so far so good. traffic around the 405 has been light today. drivers are using surface streets or most of them, i think, are just staying home. it shut down so road crews can demolish what's left of the bridge. the bridge and pillars will be replace sod that the freeway can be widened a bit. the freeway will be closed until monday morning and traffic seems to be getting an it just fine. obviously you can see the construction work right there. caltrans is warning drivers

for its plans to shut down the san mateo bridge for to two weekends next month. the shutdown will allow crews to repair a cracked support beam discovered in 2010. the bridge will be closed if all goes as planned from 10:00 p.m. to 5:00 p.m. october 19th through the 22nd and again those same times the following weekend, october 26th-29th. the dumbarton bridge will be the best alternative for most drivers looking to get across the bay to the peninsula. when we come back we will check in with john miller and mike from san diego or a preview of tonight's giants game, a game you will see here on nbc bay area in just a couple of minutes. around the bay area right now we have temperatures getting close to 90 in a few spots. we'll see plenty more of that, though, by this time tomorrow as we're watching a bit of a heat wave setting up for the bay area. the sea breeze right now is about to go away. you're going to be surprised by how hot the temperature is going to get in the seven-day forecast, coming up.

this was one of the classic bay area days, foggy, near the coast and very, very warm inland. let's check in with meteorologist and what's going on. hi, rob. >> hi. we did have the nice spread of temperatures. we did see the low clouds inland, mid morning clearing for a valleys. but the change we're going to see tomorrow is really the boundary going from cool near the ocean to just down right hot for most of our inland valleys. right now still pretty comfortable out there. 70s and 80s away from the water. we have a seabreeze pushing through san francisco and reaching into the north bay. you can see that with the wind direction. south wind at six into napa and santa rosa.

a west wind in livermore, but as that ocean air conditioning, as we like to say, really starts to back off during the day tomorrow. that will lead to at least five to ten degrees of warming for tomorrow. so for the valleys, we're talking the excessive heat watch. probably transition into a warning as we get into sunday and monday. valley temperatures mostly 90s, i think, for tomorrow. then as you get into monday, we'll probably see a range near the tri valley getting close to 100 or 105 by livermore by monday after. the coast and bay will warm up. unfortunately as that sea breeze backs off, air quality also an issue. spare the air alert. it's all the valley locations. north bay, east bay, and santa clara valley south. morgan hill, unhealthy for ground of ozone during the day tomorrow. satellite, the fog is still really kind of hung out here on the coast. right around san francisco. even into santa cruise. a cool start to the weekend. as high pressure builds in you're going to notice that fog squished down to the coast which does mean some patchy dense fog.

possibly tomorrow morning around the peninsula and the seashore. but then marine layer which started off this morning at a 1500 dpeet thick is going to get squished down closer to 500 feet or maybe even lower a few spots by monday afternoon. so what you will start to see tomorrow is five to ten degrees of warming for inland valleys which means mostly 90s around the bay, starting off the morning monday in mid 60s for lows. kind of like the running start to the temperatures for monday afternoon. so we'll see those numbers climbing another five degrees inland in the monday afternoon forecast. tonight, 50s and low 60s. thick fog possibly on the seashore. during the day tomorrow, instead of the 80s i think low 90s around san jose for your sunday afternoon, upper 80s likely south down towards morgan hill. pleasanton and livermore, 100 degrees tomorrow. mostly 90s around the east bay valleys. 80s and 90s in the north bay. even san francisco and oakland, that's going to feel a little warm, especially if you don't have air conditioning around the

peninsula. those numbers in the 70s and 80s for your sunday. so three days of hot temperatures. i think the hottest day will be monday where a few spots if they manage to get to 103 or 105 like we might see near livermore, might break some records. it would maik break some records in the bay area. cool wednesday, thursday, friday. much cooler than the way this weekend will wrap up. >> wow. i'm sort of excited for the warm temperatures though. all right. thank you, rob. let's bring in henry, comcast sportsnet for a look at sports and what a game for the as, henry. absolutely. how about fireworks during the daytime. a real disappointing first eight inning for the oakland a fans at the coliseum but it all changed in the bottom of the ninth. highlights of a crucial game for the green and gold as they try to keep their wild card lead alive. next. [ laughter ] [ girl ] wow. you guys have it easy.

i wish i had u-verse when i was your age. in my day, we didn't have these fancy wireless receivers. blah, blah, blah. if i had a sleepover, i couldn't just move the tv into the playroom. no, we had to watch movies in the den because that's where the tv outlet was. and if dad was snoring on the couch, we muscled through it. is she for real? your generation has it made. [ male announcer ] the wireless receiver. only from at&t u-verse. get a free wireless receiver with a qualifying u-verse plan. rethink possible.

welcome back to nbc bay area. the american league wild card is definitely living up to the hype. the race to the postseason a as wild as it gets. oils and as are in the driver's seetsz but angels, ray, and white sox are within reach and capable of bringing them down. let's go out to the oakland colise coliseum. hosting the mariners. 4-1, mariners. a was the chance for brandon moss. doubles to cocoa. but all of a sudden we have a plate at the plate. steven drew, wide, too late. he's out. at the plate. 4-2, seattle. bottom of the ninth. as threatening again. josh don nelson, bing binlg co.

two-run shot to tie the game up at 4-4. they were not done. extra innings. brandon moss. moss is boss right now. three runs shot. over the right field wall. his second car rooer walkoff home run. as 14 walkoffs all season. the most in the majors. as win, 7-3. >> we never say die until we report that, we're not going to quit. we showed that in texas. we fell a little bit short. today we get the last step out here and i think that's important. you know, we came through when we needed to. brandon moss, big-time homer, that was awesome. >> he's been so good for us. i mean, what a great job our front office to get him playing first base and getting him in a timely fashion when he was playing well. he's been off to the races ever since. >> reporter: meanwhile, onge and black are in san diego set to face the padres. we'll have all the action here on nbc bay area beginning at 5:30.

john miller and mike gives us a preview of what to expect. >> okay, henry, and the giants with a win last night. very strong pitching. the bullpen was excellent at the end. another strong one from ryan vogelsong but they scored three runs early and never scored again last night. >> i think that's a concern, too. i think as a manager and as a hitting coach you want to see an offense start to pile on. every inning in a playoff situation is like the ninth inning of a normal game. you have to intensity in your lineup every inning and you have to have ability to add on. opportunity is very good in san diego because they have an excellent bullpen. if you could add on late here in this game against this bullpen, it would definitely give you confidence for the playoffs. >> the giants with bum gardner tonight against eric stoltz. let's go back to henry at the studio. >> thank you. college football, california hos arizona state, fourth quarter. zach maynard is looking for

keenan allen. ten-yard td catch. my goodness. take another look at it. beautiful catch. he had four catches, 79 yards. bears kept the lead. sun devils, next possession. taylor kelley finds kevin oze,r. he takes it in for the 22-yard score. asu back up ten. cal falls, 27-17, the final. jeff and the bears now 1-4 on the season. what about san jose taking on navy and annapolis, maryland, will begin in the first quarter. travis johnson sacks tray miller. his 26th career sack. that tops the most active players, 3-0, spartans at the half. kyle makes the nice dive and grab in the navy territory. austin lopez, 43-yard field goal, freshman went 4 for 4 on the day. they shut out navy and win,

12-0. moving to 4-1 on the season. day two of the 39th ryder cup from usa dominating all day long in the morning. the americans collected three of four points, thanks to the team of keegan bradley and phil mickelson. they won 7-6. usa led 8-4 after the morning possession. then in the afternoon, the team split four points thanks to right here, ann outer. he birdied the final five holes. only european team member unbeaten. usa leads 10-6 heading into sunday's single matches. but as we mentioned, plenty of baseball coming up. giants and padres. don't forget, highlights tonight at 11:00. plus one ore other note, the raiders ruled darius hayward bay out for sunday. >> did you have to show the cal highlights, really, henry? count we just pretend that it didn't happen? >> it's been a tough start.

>> i try to be objective. >> i don't. all right. thank you, henry. popularity of poe t itry slam continues to grow. and today we actually met up with a fifth grader from the city's tenderloin whose per for mans took her to a national competition at harlem apollo theater. it's thanks to a non-profit called america scores. it provides a program that combines poetry with soccer. that's kind of interesting. today that group set out to break the guinness world record for most soccer ballses at one time. they achieved that. what they really achieved is integrating sports with learning. we will have more on the story and hear from that fifth grader to won that trip to new york tonight at 11:00. it's quite a story. first, we want to check. it is really cool. we want to check on the weather because we do have issues coming up. >> air quality and the heat, two things will make it tough. respiratory issues, outdoor plans may be effected some tomorrow as we start to see 90s on the board tomorrow.

we do have that excessive heat watch tomorrow. especially come monday as it gets hotter. as that fog gets squished down to the ocean. tomorrow we will start to see more 90s pop up at the inland. tomorrow morning not so bad. watch what happens here as we head towards 1:00. already 88 degrees in livermore. that will be the hot spot. there you see it, right there, 5:00, 100 degrees out by livermore. 90s near san jose. things are heating up. monday, should be the peak of the heat, especially in the tri valley and then cool down mid week. all right. pretty excited about it. but we'll be careful. all right. we do have a programming note due to tonight's giants game that's coming up next, revolution can be seen on channel 36 at 8:00 p.m. and then we've got "law and order" that will air immediately following the game right here on nbc bay area at 9:00. join us for our local news on the bay area tonight at 11:00.
