Today, mayor bowser said one of the pieces of legislation shes introduced today will go a long way, she hopes to keeping Race Relations between the community and the Police Department on a good footing here in the district and says one of the reason things are so good between the community and the police is because our Police Department is reflective of the diverse nature of our community.

Loretta lynch says the department of justice is committed to keeping communities safe and secure.

An appalling act of terror and hate that underscored the urgency of confronting threats in whatever form they take.

The humidity will be on the increase each day. Were talking about pretty intense heat over the next couple of days, too. Not tomorrow. Tomorrow is a little unsettled, kind of like today with the cloud cover but a couple of showers and storms. Ill show you what were talking about. Weve seen cloud cover across much of the region during the day today. 8 southeast at 9 miles an hour. A lot of sunshine and cloud cover. A mixture of sun and clouds all day. Underground temperatures, 86 in centreville. Chantilly, 87 degrees. Riverdale and tuxedo, maryland, 84. So its on the warm side today. Not hot. Not oppressive. Just on the warm side. Storm team 4 radar clear around the area but were watching storms and showers back to the west. You can see what happened. Those are the clouds. Watch where the clouds came from earlier today. From the north. Very interestingly, is like a backdoor cold front aloft came through the area and now were tracking these showers and storms to the west. Most of these should die as they move our way. Its a trough moving our way. An upper level system working our way. Well see a chance of an isolated shower or two this morning. Not going to be much. At virginia, parts will stay dry tonight. Tomorrow, a mixture of sun and clouds and tomorrow afternoon, same deal. Cant rule out an isolated shower tomorrow morning but most of us will stay dry. By 1 00, one of the waves is already through and were seeing rain around dover. More thunderstorms develop and a much better chance of storms tomorrow afternoon areawide. 3 00, 4 00, 6 00, thats something well watch out for. Tomorrow, 88 degrees. Isolated a. M. Showers and then possible scattered thunderstorms during the afternoon. We do not expect any of these to be too strong. However, we could see fairly heavy downpours. Thats something that well watch out for. Temperaturewise, upper 80s. 88, manassas. 90 in fredericksburg. Heat indices, in the 90s. Speaking of the 90s, wow, here they come. 93 on friday better every day now for the next ten days. A little bit of a heatwave . Id say so. Well talk much more about this at 4 45. Thanks, doug. Getting your morning started is going to cost a little more. How much you can expect to pay starbucks now. Not so happy workers . Ow happy yohu man hey baby, howre i have a surprise for you. Man you have a surprise for me . Narrator at dominion, 1 in 5 new hires is a veteran. And when theyre away, they miss out on a lot. But they wont miss out on financial support. Because we cover any difference between their military pay and their dominion salary, and continue benefits for them and their families. Why do we do it . Because our vets sacrifice enough. Dominion. Depend on us for more than energy. Stand by me. A moving van was spotted residents being unloaded at 10 downing street. Prime minister David Cameron will officially resign tomorrow. Theresa may takes over immediately after that and shell move in to 10 downing street. You may have noticed if you bought today and buy on a regular basis that the cup of Starbucks Coffee you got increased. As much as 20 cents more for brewed coffee and up to 30 cents more for espressos and tea lattes. The company says the price heek hike is the employees are getting raises by 5 or more. For the second time in a week, a lockdown has been ordered on the grounds of the u. S. Capitol. Im told the capitol u. S. Center and would impact more than 10,000 workers and an untold number of visitors while the u. S. House is in session in fact, they are on the floor of the capitol voting. They will be in that chamber lockdown as well as everybody else in their offices locked down. They are taking votes as we speak but the members wont be allowed to leave and the people in lockdown now in the capitol and Office Buildings will have to stay in their Office Spaces until further notice. U. S. Capitol police is the agency that orders there was a misinterpretation last week which caused a lockdown. Uncommon to have two in such a short period of time. Sheltering in place, suspicious packages are common on the Capitol Grounds. They happen thousands of times a year. But this is a more enhanced procedure and its not a very common one. Heres what happens when youre locked down inside the capitol or Office Buildings. Youre told to go to the nearest office Space Available, the nearest lockable door available and shelter there. If its your office, so be it. Lock the doors behind you. Youre told to pull the drapes or any curtains you might have in your offices and stay away from the windows. Again, they are infrequent but they are sweeping and, in this case, were told that it includes the entirety of the u. S. Capitol complex. The house Office Buildings, the senate Office Buildings capitol building. It was a few hours ago that there was a security call further from the capitol complex. Not visited by tourists. The Ford Office Building had a security call today and ended up being nothing. It was cleared just before or after lunchtime. This is the Second Security call on Capitol Grounds today but this is more significant and prominent and in stature this is a full lockdown of the u. S. Capitol. Its worth mentioning, this is not any other summer day. This is one of the busiest weeks for congress this year. Its one of the last days of actual sessions in congress before election day. They are about to undertake a twomonth recess either tomorrow or thursday. The capitol complex will be much smaller, far fewer people. This is a busy day. Not only are you going to have all members of the u. S. House, all members of the senate but because they are in session and they are here, youre going to ve from their home districts come in for the sessions of the week. Youll have tourists here. Certainly when the house and senate are undertaking their final session of the year, youll have a number of lobbyists visiting the capitol and youll have tourists as well. Its hard to imagine there being a Larger Population than it has at this moment as a lockdown is called. Were trying to figure out what is triggering this. Its worth reminding people that there is a u. S. Capitol police force. Its a large one. 1700 officers. They patrol the grounds. They are the ones who trigger these lockdowns. Theres a weapon outside the building. Thats according to an officer being quoted by reuters. They are looking for a man with a gun in the 1400 block of third street southwest. Department in d. C. They have stopped a person of interest. Lets get our bearings. The 1400 block southwest puts you on the house side of the capitol but quite a distance from the three main buildings of the house side. The cannon house, longworth and rayburn house Office Building. Youre actually getting closer to that ford House Building i alluded to earlier. A man, they are saying, possibly with a weapon, a person of interest is being detained. That might be what is contributing to that lockdown on capitol hill. As you can see, theres a business being undertaken. A floor vote is being taken right now. The u. S. House. Members have nowhere to go. They are locked in the chamber so might as well vote on something. Thats happening right now. But during lockdowns on the capitol complex, the protocols are quite clear. You go to the nearest room available with a closeable or lockable door and shelter clear. So if youre going to the ladies room or mens room, you go to the nearest Space Available and stay there until further notice. It was about ten years ago, a backfiring car in the garage of the rayburn House Building triggered a lockdown. I recall being there that day and had to shelter in place in a janitors closet with strangers. We got to know each other quite well during the three or fourhour lockdown. They are quite uncommon compared to the suspicious package calls. Its one of the most heavily secured areas. It was earlier today that some type of security c w in the ford house Office Building. Thats the furthest west and south of
