been informed, as has senior justice department officials. fair to say that official washington tonight is stunned. tom? >> that is right. pierre, thank you so much. the sudden death of justice scalia, a huge loss for the court and the conservative moment. chief justice john roberts calling him, kwoement, an extraordinary individual and admired and treasured by his colleagues. abc's martha raddatz on the justice who helped shape the bench. >> reporter: justice scalia, the longest-servg justice on the court, apparently died from natural causes. the 79-year-old justice was staying at a ranch in west texas on a quail hunting trip with friend friends. when he failed to report for breakfast, a person associated with the ranch checked his room and found scalia had passed away. >> place your left hand on the bible. >> reporter: antonin scalia was appointed to the high court by ronald reagan in 1986. he was famous for his blunt dissents. that earned him a reputation of being combative, though many who knew him personally said he was both charming and funny. one of his closest friends on the court, liberal justice ruth bader ginsburg. just last year, scalia head headlines, voicing his dissent of the 6-3 decision to uphold a key component of the affordable care act, or obamacare, calling it, interpretive jigry pokery, in which words no longer have meaning. scalia, who over the years had become the anchor of the court's conservative majority, was confirmed by the senate 30 years ago, 98-0. >> martha raddatz for us tonight. martha, thank you. let's go straight to senior white house correspondent jonathan karl. jonathan, this news is so fresh, but now there is a vacancy in the supreme court. >> reporter: a vacancy of the conservative icon of the supreme scalia was really the hero to conservatives on the court. with that vacancy, the question is, will a republican-controlled senate allow president obama to replace scalia and we have an answer to that, at least from the repeplican leader of the senate, mitch mcconnell, is already out with a statement, saying that the american people should speak in the next election, that the next president should be the one that names the replacement to jususce scalia, so, we'll see what happens. i expect we'll hear from the president tonight, and we'll see if he intends to go forward with a nomination. but i can tell you, it will be a very, very tough battle ahead th a republican-controlled senate. it would be one thing if he was replacing one of the liberals on the court. but you're talking about replacing the conservative cornerstone of the supreme court. >> now, jon, you know, you've been in court, in the supreme court for some of the oral arguments with justice scalia. what was your takeaway, sitting to close to him and what do you think his legacy is tonight? >> reporter: well, he is one hearts of opposing council, coming before the supreme court, with rapid firequestions. he could be really quite funny. i've been in the court, i was in the court for the gay marriage decision, for the obamacare decisions, both of those desions went against scalia. he was in the dissent in both cases. but as he asked those questions, as he makes his case, he could also say something quite funny that the whole court would erupt in laughter. really a unique figure in the court. i imagine that students of constitutional law will be reading and quoting and studying his decisions and his dissents for a long time. >> jon, earlier, we were reportrtg with dan abrams on the phone and we were talking about what happens next with the supreme court, now that there is a vacancy on the court. will they essentially hit the pause button in making any decisions until the election year? have you heard about that? >> reporter: you have heard nothing on that so far. forward and had decisions with vacancies, so, i don't imagine there would be a total pause button in any way, but no word yet at all from the court, except confirming, of course, that he has died. >> jonathan karl for us tonight. jon, thank you so much. now, let's get over to weather. we want to talk about that extreme weather that is now moving in. affecting 100 million people across the east coast. extreme weather and a deadly traffic pileup. a sudden snow squall in central pennsylvania, causing dozens of cars to pile up on a major entertainment. dozens of people injured. 40 hospitalized. three losing their lives. abc's eva pilgrim reporting from pennsylvania tonight. >> reporter: it seemed to come out of nowhere, blinding snow triggering this massive pileup. killing three people, leaving at least 40 injured. >> we have at least 15 people trapped on the westbound lane. >> reporter: more than 50 vehicles on i-78 in pennsylvania caught in the crash. five medical chopper rushing to one moment, the road was clear. the next, whiteout conditions. >> have all ems come to 78 and go westbound in the eastbound lane. >> reporter: snow squalls barrelling across pennsylvania highways today, catching drivers offguard. >> it just sounded like two bombs went off. there was a couple people laying out. and trucks and cars all smashed, cars underneath tractor trailers, in between tractor trailers. and it was just total destruction. >> reporter: dozens of ambulances shuttling some of those drivers to a local firehouse to keep them out of the bitter cold. tonight, everyone has been rescued, but cars and trucks still scattered on the interstate. tom, you can see the cleanup is continuing. the interstate will remain closed until about midnighgh tonight. state officials asking people to stay off the roads unless they absolutely need to travel. tom?

your home's water pipes. keep a steady drip, so those pipes don't freeze. and know where that shutoff valve is in case they burst. >> should you have a pipe freeze, should you have a pipe burst, you need to kno how to shut it off. >> reporter: and tom, another tip to prevent those pipes from freezing?

>> reporter: well, tom, we have a vacancy on the court, and it's the supreme court's conservative icon, its cononrvative ball lastast. the logical next step would be to see the president appoint a nominee. we have heard from the republican leadership in the senate, as far as the republicans are concerned, it should be up to the next president to nominate scalia's president, and with the republicans in charge, it is hard to imagine how you could have a confirmation in the final year of president obama's presidency. >> now, jon, inhe current actually wait until the next election, if that does happen, and there's a republican administration in the white house, do you see someone as conservative as justice scalia getting approved by the way politics is run right now in washington? >> reporter: well, it's interesting to note that scalia was actually confirmed 98-0, i mean, even joe biden, who was in the senate at the time, voted for him. ted kennedy voted for him. obviously, it was a very different time. and scalia was not -- not as much was known about him as we've seen in his tenure in the court. you can imagine that it is hard to get anybody through the senate, regardless of who is in control. the pattern we have seen with supreme court justices, you need nominee, you have to have as minimal a paper trail as you can possibly have, because it will be a battle no matter who is president, no mat whole is charge in the senate. thank you so much for your reporting. let's bring in abc's terry moran. he joins us now from mexico cityty and terry, you knew justice scalia's presence on the court very well. talk to us about his legacy. >> reporter: well, i started covering the court about when he came on the court. that's how long ago it was. and it's impossible to overstate how justice antonin scalia charged american law. how people think about it, talk about it, with that single idea that he had, that fixed idea of what he called textualism. that the constitution means what it meant when the founders wrote it and ratified it. the laws means, what congress meant by them when they voted on them and approved them. love him or hate him, he's not a guy that inspired a lot of middle of the road feelings, that is now in the bloodstream of american law. >> we could argue all night about his lasting impact on this country, terry, but in modern history, one of his greatest gore v bush in 2000. >> reporter: he was completely unapologetic proud of what is really one of the most controversial decisions, and for those that didn't like it, one of the worst decisions in supreme court history. he ss that it was a clear-cut case. florida was out of control with the way they were counting those ballots. he says, floridians equal protection rights were being violated. he welcomed people challenging that. that was theind of guy he was. he l led a good argument. but he was always about that for the most part, for all of his scathing brilliance, he was a very warm presence, a funny man, a man with a gift for friendship on that court. a man about town in washington, d.c., as well. he dominated the court through the force of his intellect, but also, through the force of his personality. and it is impossible to see how the conservatives come up with someone who is as dominant, that could get confirmed. >> terry moran joining us from covering pope francis' trip, but of course, pinch hitting because this is his beat. we thank you for your reporting and your insight tonight, terry. we'll have much more on the passing on justice scalia on "gma" and "this week" in the morning. i'm tom llamas. i'll see you right back here tomorrow night. thank you so much for watching. have a great evening. good night.source, this is kcrg-tv9 news at 6. we start our show tonight with alert forecast with chris havely. chris, it sounds like we have some winter weather on the way. clouds will continue to increase and thicken as we move through the evening. after midnight, light to moderate snow will develop across eastern iowa. by sunrise, a dusting up to 2'' of accumulation is ppsible. snow will continue through most of sunday, before winding down in the evening. total snow accumulations will range from 2-4'' with locally higher 5'' amounts. this snow should be rather dry and fluffy, but will certainly impact travel conditions. thankfully, there won't be an arctic air mass following this system. temperatures could drop briefly into the single digits tonight, but for the week ahead, we should drop no further than the teens . our next chance for snow arrives on tuesday, and it may be mixing with rain. tonight: snow likely late low: 5-11 winds: se 5-10 alo: 7 dbq: 7 iow: 11tomorrow: snow likely high: 22-28 winds: se 15-25 alo: 23 dbq: 21 iow: 25 back to you. scalia died of apparently natural causes at a ranch in texas. he was 79 years old. el paso abc affiliate k-v-i-a reports scalia went quail hunting yesterday. a government source tells cnn he died in his sleep. president ronald reagan appointed scalia to the supreme court in 1986. investigators in waterloo are trying to figure out what sparked a fire that killed a man overnight. firefighters responded to 16-84 mount carmel drive around 11:30 last night. that's on the north side of waterloo, near allen hospital. firefighters pulled 53- year-old ray anthony reed from the burning home shortly after 11:30 last night. reed later died from scalds and burns. fire officials say the building has significant fire and smoke damage. this is the first deadly fire in waterloo this year. an urbandale police officer shot
