said it is just easier to do it himself. the graffiti of blaster program championed by mayor daley the program has been cut by about 20 by%. despite the cut back the mayor's office said despite the cutbacks the cleaning of the graffiti has become more efficient. they are now focusing on whole neighborhoods instead of just a few walls and the community. they have put a blank wall for graffiti officeartists to work. this

would give them a venue. the mirrors that we put together so far, there's been about 1 dozen of them. they have been very well-received by the neighbors. the artists who have participated of very well known artist with in and out the city. >> it is a way for us to express ourselves. we are new urban artists. we can put something up. up there and at the same time cleaning up the neighborhood. >> at some time this is going to be like one of the wonders of chicago. it will be like the great wall of chicago. as a nice ring to it. this year workers have removed

about 64 thousand instances of graffiti. that's according to city hall. the grafitti blasters program has a current operating budget of about 4 million dollars. that's down from 9 million back in 2010. the number of drivers who filled-up their vehicles with bad gasoline may reach more than 100-thousand. the gas was blended at the b-p refinery in whiting, indiana. about two million gallons was then shipped to 200 gas stations in northwest indiana and the chicago area. and while regular unleaded is testing fine again.. the sale of premium and midgrade gasoline remains blocked until further testing. the bad gasoline can make it hard for cars to start and other issues. if your vehicle has sustained engine damage, you can file a claim with bp. phone numbers and website contacts are on our website coming up, what happens if hurricane isaac moved close to the site of next week's

in tonight's medical watch shedding new light on the bladder cancer. it is not new light but a dike that helps the doctors thought cancer cells and have missed with the naked eye. this may make a significant difference when it comes to a patient's outcome. six years ago he was diagnosed with cancer. they removed his bladder, prostrate. this week a second diagnosis this time cancerous cell found in his kidney and liver. bladder cancer when it does recover it most commonly recurve in the lungs liver and bones. we are talking about needing pretty powerful

chemotherapy. it is a chain of events that doctors would like to derail spirit they would like to stop bladder cancer in its tracks. >> we take a small telescope through the patient's urethra and look inside the bladder. >> a standard wide like guides the doctor to the legion. the procedure is not perfect. >> you have to look around corners almost to say in the entire bladder. we miss certain tumors we just cannot see them well. we know that because the return today is to repeat the procedure and we pick up new tumors about 30-40 percent of the time. we do not think those tumors that are new we think those are tumors that we miss in the initial diagnosis. >> this doctor was easier to try this procedure. a new contrast died that has a particular protein. it has light blue and

is armed with a blue light. >> it sounds so simple but that really helps make it easier. >> 69 year-old man went under the procedure at the notice blood in his unit. the scope made its way to the bladder. when the doctors to join the blue light, a sea of neon pink lights up expanding well beyond the tumor. >> i think that you can spend a lot of time and look very carefully with the white light and potentially find a majority of tumors, there is no question in go easier with the blue light. >> i am very grateful that i am one of their early guinea pigs for this institution having the procedure. >> now this grandfather can focus on his family. but for patients like cardinal george whose cancer has spread, there will be many more rounds of treatment. dr. steinberg believe that if blue light procedure had

been available at the time of his original diagnosis it may have changed the outcome. it seems to have fewer side effects than the other photo procedures. some of the other procedures caused a lot of photosensitivity leaving patients unable to go into the sun. >> the 90s are back. they want to know how long they're going to stick around. tom skilling has the answer in a full forecast coming up next. with simple online ordering and curbside pickup

we are looking at mr. skilling racing up to the news center. we are really excited to tell you about our trip to the hurricane center. the top of heat and pictures like this. this is a thunderstorm that was shot in whiskey in wisconsin. the storms build up to the stratosphere and then angle out. this one was

captured in indiana. the turtle crawled out there and there it was. montgomery capped a beautiful sunset tonight across the area. it has been a beautiful day. we have a 90 degree temperature without all the humidity. what a gorgeous day. we started with cement and high-level cloud cover. we warm up and got some nice warm days on the way with humidity building at the pretty good storm with rains later in the weekend. a lot of the attention is down in the tropics where we have a isaac moving across the caribbean and headed for haiti and the dominican republic. the storm was strengthened slightly tonight with 45 mi. per hour winds. here is a look at what it looks like. the purple areas

show the winds. the storm is expected to cross into cuba within the next 48 hours. these have unsettling south with time. tampa is where the convention is and here is how the storm is supposed to move through the florida straits. in the open water of the gulf, they will pick up strength. this environment is highly interested for strengthening. if it moves up into the warm water here is what it might look out like by the time he gets to sunday afternoon. i want to show you the diversity of model solutions here. this one takes an almost to louisiana and texas and oklahoma. one of the weather service models takes a little further west but still has it heading towards the northern

gulf coast. look at the showers with the system right now. they have been casting about a pr right here. the showers are producing 40 mi. an hour winds and downpour. as for us, the storm erupted in the monsoon area out here in the west. on the north fringe of it, we are getting thunderstorms over the twin cities. that is a sign of what can happen with daytime heating. later sunday and sunday night into monday morning we could get some good rain. the war has fanned out into our area. tomorrow we will have the 42nd day at 90 degrees. we are within five degrees of the all- time record. we had 92 at

o'hare. at 92 at the lake front. 41 states were in the 90s today. our weather temperatures are in the '90s and forest park, feldmanalgin and winfield. there is a red flag warning in the red flag area. we are three degrees warmer and looking for warm air.

we 90s tomorrow and saturday making it the longest string of '90s we have had this year. more and r update coming up on the rain situation. tonight is windy and warmer. in the low 60s. we have what is called a nocturnal jet developing that will keep the wind blowing stronger at night than in the early afternoons in some cases. mostly sunny breezy and hot tomorrow. tomorrow night scattered clouds. mostly sunny. moderately humid and 91 degrees on saturday. coming up immediately making hurricane forecasting even better. we want to introduce you

to some of the scientists who are working at that down in florida at the hurricane center and the hurricane lamp. that is coming up so stay with us. el

as we showed you, there's much at stake depending on which path tropical storm isaac will take -an example of the need for extremely accurate hurricane forecasting. the national weather service is now four years into a ten year study to improve hurricane forecasts. researchers have become very good at predicting the path of a hurricane. so good, errors are half what they were twenty years ago. but what they dont fully understand is why one hurricane blows up into a katrina and others fizzle. >> 'it looks like a concrete bunker. it has to survive the winds of a hurricane. this is the national hurricane center in miami.' >> 'we have some hurricane nuts here!' >> chris landsea is admittedly one of those nuts. here, they analyze a hurricanes location, strength, and size. >> 'ok, lets look at what other possibilities we have- let me take a look.' >> they use that information to issue hurricane forecasts for the next five days. landsea was born and raised in miami and has personally experienced the destructive powers of the

greatest storms on earth. >> 'after hurricane andrew that destroyed my parents house and then hurricane wilma that caused some damage at my house i think ive had enough hurricanes hitting me.' >> 'hurricanes are immensely powerful. the amount of energy that a hurricane is releasing all the time is roughly equal to the whole earths electrical production. thats one hurricane.' >> when hurricanes threaten our coastlines, americans hang on every word from here. >> our number one mission is to save lives and property.' >> bill read just retired as director of the national hurricane center. read says hurricanes are rare events - only six to ten a year is the long term average. >> 'picture the gulf of mexico with no satellite, no aircraft, no radar, and you didnt even have in 1900 a ship to shore radio yet. a ship got hit you find out about it if it came back to port.'

>> with satellites we now *see whats happening in real time over our oceans. and faster computers calculate simulations of how a storm may evolve. but the trick is giving computers the data they need to make accurate predictions. >> 'you have to get very detailed, high resolution measurements of whats going on right in and around the eyewall the eye, the surrounding area around the core. by and large we dont have those measurements. so, its no wonder the computer models that arent being fed the information they need have problems.' >> enter the hurricane hunters- military personnel who fly scientists into hurricanes. >> 'there is nothing like having a flying laboratory which is what the aircraft are - collecting data inside the storm. were dropping instruments from the belly of the aircraft collecting data.' >> by flying criss cross patterns and peppering the storm with instrument packages tied to parachutes, they capture

all quadrants of a storm and drones are now being used to linger in storms that would be too risky for humans. >> i was learning a lot about hurricanes from these data sets but i wasn't seeing it being used in the models. and that's been a real revolution for us.' >> theyre also looking at very complex microphysics. whats happening in the ocean and how the air and sea interact. >> 'this is the saharan dust.' this particular dust kind of hangs around in the mid levels of the atmosphere. so, it sort of impedes the growth of hurricanes.' >> getting answers to storm intensification cant come a moment too soon. >> '50% of the people in this country live within 50 miles of the coastline and you can see why, it is beautiful! here in miami beach, people work play and live as close to the water as possible.' so as the coastal populations grow - accurate forecasts that give adequate evacuation lead time become ever more critical.

>> 'if you live in a hurricane prone area, it just takes one. you be prepared! and that message has got to come out.' dr. marks says our high tech world makes us far more vulnerable to weather-related disruptions. and when we asked about global warming, our experts tell us if the climate models are right and there is substantial global warming in the next few decades, there would be more wind shear affecting the tropics which would actually mean fewer hurricanes. but the ones we do get may be stronger. that kind of interesting. this is such a timely thing because some of these improved models are being incorporated in the forecasting technique on isaac. we are hoping to improve these

forecasts even more. i think we are going to hear a lot more about isaac before it comes ashore next week. and what is in the white house of beer recipe a lot of people are demanding that the president share the secret. and the first place white sox are getting contributions from some key in- season acquisitons. later in sports, we'll talk to one of those acquisitons you do this every morning? it's the only way to get fresh coffee. not in my house! this new flavor lock pack from maxwell house helps seal in freshness. wow! that is fresh! am i still yelling? [ male announcer ] maxwell house flavor lock. always good to the last drop.

the white house has a secret beer recipe and thousands of people want the brewer-in-chief to give it up. it's called "white house honey ale.." and beer fans started an online petition, demanding president obama's home-brewed recipe. one blog has even filed a freedom of information act request to get it. a white house food blog says the chefs have brewed up three types- the honey ale, a blonde ale and a honey porter. and the honey used in the beer comes from the white house bee- hive. >> you know they're all those great microbrews coming out.

guys we have a beautiful string of days ahead. humidity will start creeping up and it will turn him it over the weekend. it is still moderate humidity but stormy later in the weekend. everyone of the next five days are days 135, 6 through 10, 11 through 15 is above normal. that means that the next few weeks will be above normal. you can see the system down in kansas in the plains states coming together even as the tropical storm moves then on southern florida. here is a forecast of how many grain will come down. and here are the temperatures tomorrow. lichted how widespread the heat will be back in the plains states tomorrow. for tomorrow chicago will be a 93.

in 5 minutes or less guaranteed, almost anyone can do it. this is easy. this is sears. we have some question that the bears are answering tonight. the bears and did releasekahlil bell, who had a hundred yard game against the packers last year, was released by the bears after he refused to take a 500-k pay cut. he was buried behind matt forte and michael bush, now trying to hook on elsewhere. bears are in the big apple tonight, gettin' ready for the giants and that frightening pass rush both chris williams and j'marcus webb will see time with the first unit at left tackle as they try to firm up that spot. this could be the game that decides the issue. they'll be playing against the best at the meadowlands tomorrow night.

>> i would think you would rather to see this. you want to go out there and play against the best because it calluses you and make you a tough not only physically but mentally and now you really get a chance to evaluate your players and see where you're at. >> that's really the only fair way to get a great evaluation when you have a chance to let guys played against the same guys early in the game in situations like this. >> the white sox get a well- deserved day off. it may have been a shopping day for some of the guys. they have a big event this weekend. for kevin euclid and allison read it was a charity event in a bid for youth is. kids of disabled servicemen and women. this is very nice, and on the heels of the yankee series.

>> in the last couple of weeks we start paying attention a little bit more. it is something a look at after the game. we're not letting that bother us, we cannot control what they do. >> bad news for the tigers. miguel cabrera out early against the blue jays with a sore ankle nothing serious. justin verlander did not beat the jays today, but the jays couldn't beat the tigers, either. bottom eleven, alex ah-vee-la base hit to right field brings in quentin berry. tigers finish off the sweep, 3-2, remain within a game and a half of the white sox, who had the day off. sox have gotten a big lift lately from an old favorite. dewayne wise was released by

the yankees, picked up by the sox and he hasn't stopped hitting since. sox fans remember d-wise more for his defense - 2009. mark buehrle working on that perfect game in the ninth against tampa bay and wise saved the day at the wall. hard to imagine this guy was almost out of a job until the sox rang him up. >> i knew it was going to be tough to find a job. i knew the only way i was going to get a job was to try to get into postseason. is just a blessing to go from one team who was in first place to go to another team in first place also. i am just thankful to be somewhere that i am comfortable at. and getting the opportunity. >> seattle tomorrow and it's playoff time at the pga tour. tiger woods is the top seed. he had a good round today. it was

four behind it later. tiger played with rory mcilroy. they will try it again tomorrow. that's the news for this thursday night. we're happy you shared time with us. for all of us here have a great night. good night. fo
