for the early part of the evening, 4, 5:00 a sprinkle or 2. we clear out and cool off rapidly. when the sun goes down after 7:00 we'll be diving back down into the 60, so it's going to be a quite cool evening around here. tomorrow we'll bring in a small chance for a thunderstorm. saturday and sunday we are sunny and dry here. we're heading back up for the weekend. >> 80s are sticking around i guess for thank you. mental health is a huge topic in american culture these days and police department are trying to make sure their officers are properly trained. we are joined live from the littleton police department. and they've become the latest department to join this growing effort. >> reporter: yes, it's called the co-responders. now, we've seen police departments across

the city of denver just announced that it did expand its co-responders program. it went into effect april of last year and they've already responded to more than 400 calls through april of this year. the city of littleton joining in on that effort developing its own co-responders program partnering with all health networks. that group treats thousands of people every single year for mental health difficulties. basically a police officer will be a professional if they respond to a call and see that a person in that situation does need a mental health professional. that partnership they think will help to save police a lot of that time consuming work of trying to assess that situation, but they are also trying -- in assessing situation through something very important that officers receive training with it's called crisis intervention technique. a littleton police

works. >> it gives officers more tools. these officers are moment to say make assessments of the scene, and so once you can make the scene safe it's about getting treatment so that they can hopefully not have to return to these situations, the same situations. >> reporter: and and not leaving people in dangerous situations also not just throwing people in jail who may be having a mental episode that's something the commander spoke of. it's 6:04 now. 2 of our fallen local heros are finally coming up. levi shirley and mctaggert were killed in syria. their bodies will be returned to colorado tomorrow. they were both killed about a month apart. a special ceremony for their

the state. we had a shower up in wyoming a couple of hours ago that has fallen apart. low pressure hangs off to our north and west. that's bringing more and more dry air into western colorado and southern colorado but it is putting a big focus for thunderstorms along the wyoming and nebraska borders for us today. so the farther north you live here in the front range the better chance you have of having a shower today. i'd say from around bertha to the south way way down, to the north and east we'll have a pretty stormy night in my view. that's where we'll see the best consistent rain. just a few light showers around here. it's still going to be a warm day. mid to upper 70s with sunshine feels very warm when you're out and about during the afternoon. 60s and low 70s in the foothills. fog over the northeastern plains is going to burn off to be replaced by thunderstorms not only this afternoon but this evening after sunset i think we're going to

the your take section on 9news.com. we're starting to see more and more delays. taking a look at sky 9 this is i-70 and 6th, that's the emergency bridge repair. the repair is expected to go on until 7 p.m. this evening. so you could take coalfax, i-70 but you may want to avoid that 6th a couple of other headlines across the metro airlines e and f northbound riders you're seeing a 30-minute delay there's been technical issues and the roadways still looking green northbound however southbound we have numerous accidents one on i-225 southbound. so unfortunately the traffic is starting to ramp up. >> all right.

their job and helps mental health professionals to get out and get to the people who need their help the most. now, this co-responders program technically it's not new if you look across the country. one mental health professional says it may have started in the '80s in memphis and spread slowly across the country. just within the past year we've seen it grow in colorado. for example, the city of denver has expanded its program. they've already responded to nearly 500 here in littleton the police department is partnering with an agency called all health. when a police officer goes out on a call that officers will be able to call a mental health professional with all health. they treat thousands of people every single year. on top of that police here have received training that helps them to really assess situations even before a mental health professional arrives. so when they respond to a call what if there's no crime that's been committed and a person is just

deal with that? >> we do respond to a lot of calls where a criminal act has not occurred and maybe a person is going through a crisis moment. once we deem that the situation is safe we can still call them in and if there was no crime committed then absolutely we would get them down that treatment path first. >> reporter: that's one of the goals of this program, not to unnecessarily throw people in jail. people realize that that's not productive for either the person thrown in jail or the police department. so they're trying give people the help that they need. and the commander that we spoke with said let's be frank police and community relations have not been great the past couple of years. as we've seen throughout the media, he says this can go a long way with improving relations. so this
