Good evening, im tom llamas. We begin with a fierce blast of winter. A night of cutting winds and dangerous cold still ahead for millions. Heavy snow from north dakota to maine, 27 states feeling the wrath of winter this weekend. Boston, now with its snowiest month on record. Powerful winds blowing across the country. Listen to this. Nearly 40 miles an hour here in michigan, and on this long holiday weekend, multivehicle pileups littering the roads, delays and cancellations on rails and flights. This special machine clearing the tracks in boston. And while the center of this storm is moving out, a new storm is coming to the south. With more than 100 million in its path. That forecast in a moment. But first, rob marciano starts us off. Rob . Reporter the winds are blowing in boston. Coming in behind this system that tore up the u. S. And when it hit the atlantic last night, rapidly intensified, once again bringing blizzard conditions. To the new england coast. Yet another big storm barreling through new england. Theres a little bit of deja vu all over again in this. It will be our fourth major storm in the past three weeks. Reporter adding even more snow. To a record snow pack. Snow drifts up to six feet high on top of this warehouse in seabrook, new hampshire, caused its roof to collapse. Thankfully, no one hurt. The deep snow also blocking tail pipes and exhaust vents. On the coast of massachusetts, it was snow and wind. Gusts over 70 miles per hour. And waves. Snow blowing sideways all morning long. Were at high tide. On top of that, a storm surge is flooding parts of the peninsula. The wind is the big story with this storm, even, so this will put us over the sevenfoot mark in the last four weeks. And with almost eight feet for the year, boston will likely set an all time record. Its to a point where residents and reporters just have to laugh. Shovel. Right in the neighbors yard. Theyre okay with it. Theyre good people. Reporter and as this storm exits, the seasons coldest air blows in. Here it is. Right now, windchills at minus nine. Will go to minus 20. Setting the stage for a storm that will once again head this direction. Stand by, well come back to you in a moment. But all that Winter Weather is making it hard to get around and dangerous. Gloria rivera on that story tonight. Reporter extreme weather disrupting travel in any form. If i wasnt going to work, id be staying home. Reporter today in chicago, subzero temperatures and slippery roads triggered this 38car pileup, shutting down the citys main artery and injuring 15 on the road. From michigan to indiana to ohio where wind gusts and whipping snow blinded drivers. Its been a deadly weekend on the roads. Whiteknuckle driving in whiteout conditions. This morning, as we were driving, the visibility dropped almost foot by foot as that storm came in, going as low as a quarter of a mile, making it very difficult to see. But now there is another concern ice on these roads after hours of wind chill and freezing temperatures. Airlines already canceling at least 1,900 flights today, setting up a busy and backedup president s week. Here at new yorks la guardia airport, there are determined flyers taking their chances. Tomorrow will kick off with a backlog of all those that didnt get out today. Tom . Thank you. I want to bring in rob again. More bitter cold moving in . And another storm on the way . Yeah, and this will hit the south. So, snow and ice getting into at least the midsouth. Looking at the wind chills, minus 20 or better in boston. Upstate new york, 40 degrees below zero. Dangerous, lifethreatening stuff. As this cold air pours in. And the storm is developing across arkansas, into the tennessee valley. Looking for snow, and ice, and reaching its way towards the midatlantic coast by tomorrow morning, and into new york. Potentially by tuesday morning. Heading this way tuesday night. Snowfall, could see a foot in kentucky. And icing across parts of the south, maybe a quarter of an inch. The next 24 hours, across that part of the country, certainly going to be dicey. Rob, thank you. We go to denmarks capital, copenhagen, a city under alert after two deadly terror attacks. This, after police say they killed the alleged gunman overnight.

I could hear in arabic. And the shouts. Reporter one man, a danish film director, killed. Three officers wounded. The apparent target, this man, a swedish cartoonist. Wanted on an al qaeda list for drawing the prophet mohammed as a dog. The organizer of the meeting, telling us the bravery of the guards saved many lives.

One man killed, two policemen wounded. They were protecting families celebrating a bat mitzvah. Hours later, the gunman was killed, identified as a 22yearold known gang member. With a violent record. And today, police raiding an internet cafe, making several arrests. The attacks in denmark come five weeks after the attack on Charlie Hebdo in paris. Sparking fears of copycat attacks across europe.

Martha raddatz reports. Reporter terrorists coming from around the world, including just across the jordan iraq border where isis flourishes. And driving along the border, we saw jordanian tanks there. As fears grow that isis fighters could bring the battle to jordan. After the shocking execution of the jordanian pilot, burned alive, much of the arab and muslim world rallied against isis. But that execution and the Coalition Airstrikes have also galvanized legions of isis supporters. Young men like those we met outside of a mosque are inspired to fight. What is it that motivates you to want to go to syria and fight . Syrians are our brothers. When you see theyre being killed, thats motivation to fight. Reporter many who answered the call to jihad have been encouraged by this man, abu sayed. A radical cleric that had been imprisoned for leading antigovernment protests. He said isis immediate a mistake by burning the pilot but defended sending fighters to syria. This is for the sake of god that we went to fight in syria.
