the deep freeze continues with some of the coldest air in years. we saw snow flurries this afternoo afternoon, but tonight, the big concern is the wind advisory in effect for a big part of our area. >> doug, how low will it go? >> well, not as low as last night, even though it is going to be feel colder because of the wind. last night, dulles dropped to 2 below zero which is the coldest they have seen in 18 years. and yes, some snowshowers across the region and there they are coming through with the clipper system to move rapidly, and as it did so, it brought the temperatures back down, and the winds, too, and that is why we have the windchill advisory, and currently 16 in martinsburg, and 21 in culpepper and the windchills in the single digits, and we will see them in dangerous levels especially back to the west where the windchill could be between 5 and 10 below zero. that is what we are going to continue to see through tomorrow morning, and the windchill advisory continues until.

:00 a. 9:00 a.m., and we will let you know when the next chance for snow and colder air moves in. >> thank you, doug. cars frozen in several inches of ice tonight in the district. a broken water main turned the sheet into a thick sheet of ice. in another area sidewalks are treacherous even though there are laws that require them to be cleared by now. mark segraves in northeast d.c. with more on the troubles of getting around. mark? >> well, jim, i will tell you what, neighbors tell me that the water main has been leaking since early december, and they have been calling d.c. water about it, and look at what has been doing to thor cars here. frozen in ice. right up to the tires. and it is not just here on taylor street, but all across the region, and side waux covwa covered with ice are making the traveling treacherous and particularly for the elder ly. >> it is, it has been pretty

rough, you know, trying to walk in the snow and the ice and hoping that i don't fall. >> reporter: 71-year-old verdina cunningham was trying to get to the store after being inside since the snow. but the icy sidewalks and her petworth neighborhood were too much for her. the icy sidewalks in front of the bethesda library proved a challenge for this mother also trying to get to the store after being snowed in. >> it is very difficult when they have not cleared the sidewalks, it is very hard to walk. >> reporter: and the conditions not much better in front of this arlington school either. across our region, we found businesses and government buildings who didn't bother to clear their sidewalks. this is what we found at one government office building the d.c. crime lab and the sidewalk completely cleared and almost dry, but next door at the d.c. firehouse, this sidewalk is covered in ice, and almost impassable by some pe des tdest and look here, where the firefighters park their cars, that lot has been cleared. by far, one of the worst lots

was taylor street in northwest d.c. where this water main has been leaking since last month creating an ice dam on the street that has some cars froze en in place. >> it is not looking good out there right now. it is kind of annoying. >> reporter: the neighbors have been complaining to d.c. water since early december, and while the salt trucks have treated the street, the water main has not been fixed, but within 30 minutes of news4 calling, d.c. water crews showed up. and now those dc water crews have been here since this morning when we call, and an official says that the water break was not a priority because it was small until the freeze hit and made it so much worse that it is going to be fixed in a matter of hours and look at this here, to give you an idea of the ice cleared off here, this is the pile of ice on taylor street, and they are asking the crews to help them get the cars out of the ice. that is the latest, reporting

live, mark segraves, news4. all of this cold is putting a strain on the power companies. and pepco is asking customers to conserve tonight, and then again tomorrow from 6:00 to 9:00 a.m. which could include lowering the thermostat and using the electric appliances late at night when the demand is lower. the power strain is not limited to the d.c. area. it in fact is affecting 61 million people in 13 states. >> the icy weather may be to blame for the big pileup outside of chicago. this video taken 25 minutes ago at last count 12 semi trucks were involved. these are live pictures that we are seeing now, and a number of cars that we know have been involved and two people killed and several others injured and this is on michigan city, ind n indiana, about an hour east of chicago. it is a mess. and now to the developing story out of bethesda, and commuters taking massachusetts

avenue out of the district will have to find a new route toni t tonight. a crash several hours ago closed down the stretch of mass avenue near sangamore road. a driver lost control of his car this morning, and hit a utility pole sending the wires into the road. and a dump truck spilled its load in gaithersburg on fredrick road and montgomery village road. we do not know what caused that accident, but nobody was reported injured. and tonight, lawmakers are outraged with the attorney general's stance on not defending the ban on same-sex marria marriage. polls showing that the majority of virginians are favoring same-sex marriage. it is now legal for gay couples to marry in seven states, and

be held in federal court next week. in 2006 he voted against same sex couples marrying, but he said that his views have changed. >> i have come to the conclusion that i wouldn't want the state telling my son or my daughter who they can or cannot marry. >> reporter: but herring's decision does not change the law. the ban will be enforced in the county clerk's offices, and many republican-elected leaders condemned herring's decision. >> he swore to uphold not only the constitution of the united states but also of the commonwealth, and this is a legitimate part of the constitution of the commonwealth, and he has a sworn obligation to uphold and defend that. >> and he is forcing a constitutional crisis. >> reporter: prince william delegate bob marshall is one of the authors of the law, and he says that the attorney general won't befend it, he is appointed to someone who will. he threatened to cut it off. >> well, if he acts like a

rogue, he won't get money from the assemble. >> reporter: but those who are battling call it tremendous moment momentum. >> it won't change today, but it can move the process along. it is not if, but when gay marriage comes to virginia. >> reporter: and now a hearing will be held in norfolk, and he says that he does not know if he will attend the meeting but the virginia's solicitor general will be there to argue on behalf of the commonwealth. and former governor bob o'donnell and his wife are to be in court tomorrow. scott macfarlane will have a unique look at the case in the next half hour. and the man who admitted shooting the former redskins' star sean taylor is going to spend more than 57 years in priz sovnlt a judge announced that sentence today to eric rivera. rivera is 23 years old now, and he was convicted of burglary and

second-degree murder back in november. he confessed to firing the shot that killed taylor after he and four other guys broke into taylor's house more than six years ago. today, rivera apologized to taylor's family. taylor's father spoke ability the pain of his family and for the fans of his son. >> i deal with the death everyday and i'm going to have to live with the consequences and i'm truly sorry. >> this has to be one of the most difficult things that a father or redskins' fan can go through. >> both taylor's mother and father accept the sentence, and the three other men charged in the case are waiting for trial. >> and today, they are calling for an end to the nsha's collection of bulk phone records. today, they recommended far more sweeping changes than those announced by the president last week and it did not take long for nsa leaker eric snowden to

react. steve handelsman is on capitol the hill with more on that. >> well, this is no little committee, but a board set up by congress in 2004 and so it is significant that the board's findings today and its suggestions are the opposite of what president obama said he would do a week ago about the controversial program first revealed by edward snowden. >> reporter: the privacy and civil liberties board investigated in depth the phone data collection, and the phone program, and every call logged and save and the board concluded it is not legal. >> the government should end the bulk tone records program. >> reporter: and the program did not stop the boston marathon bombing. >> the expectations of the program have fallen short of the highly desirable results expected. >> reporter: some members found that it helped ongoing
