The snow. And 200 troops from New York National guard arrived to help with snow removal, but the new york Governor Cuomo warned the snow is just too deep in some areas for plows to work properly. Nbc meteorologist dylan dreyer joins me from hamburg, new york where conditions are changing by the minute. Hi, tamron, literally by the minute. Minute to minute, you can go from brutal windy conditions to not much snow at all. Then if you go a couple miles over, you can see downpours of snow, or nothing at all. Right here, we are seeing nothing at all. I can see clear skies if i look to the west. If i look to the southwest, really dark clouds. Thats where heavy snow is, falling at rates of three to four inches per hour. That line will move back up here, where you can see we have feet of snow on the ground. We could see another foot, then it moves back south. The little bands of snow, this lake effect snow, about 15 miles wide, 15 miles long, and they set up shop in a couple different towns for a few hours, then move on. Unfortunately where they sit, they could produce inches upon inches and feet upon feet of snow. We do have a major concern going into the weekend. Temperatures are going to get up to 50 degrees. So all of the snow will begin to melt. Add on top of that some heavy rain and all of the snow, it is very light and fluffy, it absorbs water like a sponge, it will add all of the weight to the roofs that the snow is sitting on now. The next concern could be flooding and roof damage and roof collapses. Once we get into warmer air this weekend. You would think warmer air would help things. Unfortunately it could make them worse, tamron. Incredible to see so much snow in a short period of time and more to come. Thank you very much. Lets go to msnbc meteorologist. Looking at today and tomorrow with more snow in the forecast. The good news, taking a look at the radar, the heaviest band of snow is coming in just south of where the hardesthit part was in south buffalo. Thats where the snow band is. It is ten miles now sitting to the south. It is expected to start to move to the north as we push through the afternoon. Nal start to push further north. Snowfall rates of 2 to 4 inches continue through the afternoon. We are looking at right now places like hamburg and even further east an additional foot to come into play. Theres a live look now. You can see the snow is at a lull, but again, as we move through the afternoon that snow will start to ramp up once again. Tamron . Thank you. Now to politics. As president obama prepares to announce tonight that he is taking executive action on immigration, what political headlines have a say. Obama goes it alone. Obamas go it alone immigration move. Apologize for that. The president speaks at 8 00 p. M. Eastern time, expected to announce his use of executive authority, which he insists he has to allow as many as 5 million undocumented immigrants to stay in the country. They include undocumented parents of children born here. The president s plan would protect more dreamers, young people brought here illegally as children. And it would extend the stay of foreign graduates of u. S. Colleges with high tech skills. The president gave a preview in a video on facebook. Everybody agrees that our immigration system is broken. Unfortunately, washington has allowed the problem to fester for too long. So what im laying out is things i can do with my Lawful Authority as president to make the system work better, even as i continue to work with congress and encourage them to get a bipartisan comprehensive bill that can solve the entire problem. But republicans insist the president is acting illegally. We are unfortunately witnessing a constitutional crisis. What president obama is doing is he is defying the law, defying the constitution. If president obama acts in defines of the people and imposes his will on the country, congress will act. Were considering a variety of options. But make no mistake, make no mistake, when the newly elected representatives of the people take their seats, they will act. Joining me live, democratic congresswoman, Sheila Jacksonlee of texas, Senior Member of the house judiciary and Homeland Security committees. One of the most outspoken proponents of comprehensive Immigration Reform. Thank you for joining us. Thank you for having me. Let me play what the president said september last year regarding executive action and Immigration Reform, and contrast that to what he is saying tonight and what we heard from him earlier today. Lets play it. Young people who basically have grown up here are americans that we should welcome, were not going to have them operate under a shadow. But if we start broadening that, then essentially i would be ignoring the law in a way that i think would be very difficult to defend legally, so thats not an option, and i do get a little worried that, you know, advocates of Immigration Reform start losing heart, and immediately are thinking well, you know, somehow theres an out here. If congress doesnt act, well just have the president sign something and that will take care of it, we wont have to worry about it. Congresswoman, compare that to the president now in this proposal we have seen. Isnt it broadening the plan beyond what the president was initially looking at, which were the dreamers . You know, tamron, i think the president s words then are as true for him today, the president indicated his broad authorities, as broad as they may be under executive powers, does not give him authority to convey citizenship, and nothing in what we have seen in his proposal conveys citizenship. And it also reflects a thorough, constitutional study on his executive powers. If i can just frame for you one or two points. He goes immediately to issues dealing with Border Security. The president has enforcement powers, has the ability to determine how you enforce the law. He is going to be adding taskforce to Border Security to make it more efficient. Thats within his powers. He is going to continue the deferred adjudication, which is in his powers, does not convey citizenship, he is going to give them a period of time, let youngsters have the authority, have that provision for three years. He is doing administrative and using prosecutorial discretion authority. And if the republicans would simply calm down and listen to what the president said, which is im inviting you to the table of collaboration, im inviting you to do what is right for the American People, will you accept my offer, can we go further together and actually do comprehensive Immigration Reform. I want to play what josh earnest, White House Press secretary said on morning joe, why not wait until new congress has a chance to act. Lets play what he said. Were doing it now because House Republicans have indicated theyre not bringing up that Bipartisan Senate bill that has so much support. Two weeks ago when Speaker Boehner was asked by the reporters if he would commit to bringing up Immigration Reform legislation in the next congress, he wouldnt do it. That was on jose diazbalarts show. Nevertheless, you look at the landscape and have people wondering why not wait, do you believe the explanation given by josh earnest is the appropriate one . Do you not see the line of progress available in the house that you know so well . This was the first year the president or even first year of his second term, i would say yes. Then i would say yes to what was said about the republican attitude. The speaker of the house said directly to the president i want to do Immigration Reform. This is beginning of the second term. We passed a senate bill. It has been languishing for 500 days. No action has been taken. And theres an internal dna opposition. It seems to be some fear, some fierce fear of innocent people who simply wanted to come and work, and theyre across the gamut. Polish, irish, from south and central america, africans, from the caribbean. I believe there is no pathway forward except for Speaker Boehner committing to his house and to the new leader of the senate to actually stand up and tell the American People that we are prepared to work with the president as democrats are. But i cant see the president allowing this humanitarian crisis to continue. And that is the tearing away of parents, innocent parents, children left abandoned, young people wanting to go in the United States military but cannot because theyre unstatused. Children who are bright and brilliant wanting to go to colleges, valedictorians, unstatused, want to contribute to america. I think the president is within his constitutional authority. I dare the republicans to challenge on that basis. Why dont they do the humane thing, what the American People want done, we stand and Work Together to fix this in the right way. The law is still there. Let me talk quickly about texas, our home state. You said 1. 3 million undocumented immigrants in texas alone. Many paid taxes. Many children are born you have some 5 million people, this is some arbitrary number. Why not take a bigger step, when working at 1. 3 million alone in just texas. Im glad you asked that question. Certainly there was the proposal to allow the parents of children who had deferred action, but heres i think the reasonableness of the president and concern of constitutional authority. He vetted this with his legal council, constitutional experts. They narrowly drew this order to be sure he was in confines of his prosecutorial authority, and in his humanitarian relief authority. I think if the American People look, theyll see this is not a runaway president , who desires not to work with congress. It is a president thats begging for the reasonableness of these republicans to be americans and to stand collectively to solve an american problem and lets do it together. He is within his authority and doing the right thing. There are too many people in pain. Thank you very much, congressman Sheila Jacksonlee of texas. Thank you. Bring in columnist raul reyes and mike sacks son. Regarding the number of people the white house says this would impact, how that strategy plays into the legal argument being made perhaps by the administration. Right, the administration doesnt cite the number being vastly greater than the 1. 5 million affected by president reagan first president bush. But the text of the law itself, says any alien shall upon order of attorney general be deported if they are part of so and so category. Shall, the word shall the republicans will say see, this is mandatory, he cant say that. The democrats will say upon the order of the attorney general, which makes it subject to discretion. So that will be the legal issue at play here, should the house, should the senate, should a state, should a labor group try to sue and get the president to rescind or struck down the executive order. Raul, the American Immigration council identified 35 times since 1956 that president s used their authority to grant relief to immigrants. Right. 11 president s in that time. You can go back further to as far back as roosevelt when he created that program, Congress Later approved it, when it expired, truman went back, started it again. Executive authority on immigration has a long tradition and history. That said, what people are looking for tonight, obviously the immigrants Rights Groups want him to go as broad as possible. Thats the hope. That goes against what the president said in his own words last year. Probably the upper limit of 5 million. Inevitably, there will be winners and losers. Citizens with children will be likely eligible for deferred action. That leaves out, for example, people from other categories, lgbt groups, and day laborers, Migrant Workers that tend not to come with their children, they will probably be left out. It will be a bittersweet moment. Very exciting for immigrant rights community, that they pushed it through young people, forced the president to take action, but theres a line drawn. Some will be in, some will be out. Which means some people will be upset about this because of the lingering battle thats taking place, and raul, as you know, the promises made by this president. Right. With these promises, his promises go back as far as may. He delayed doing anything all summer in the hopes of letting john boehner put something through. Each one of these delays created greater and greater expectations. If theres some disappointment, part of it is the president s own making. People are trying to find a way to be hopeful. I talked to many dreamers, depending on who is in and out, theyre going to continue to push and work and find a way to press the president to give additional administrative relief for other categories further down the line, because no one thought they could come this far. So far, the public does support this action. 52 to 44 in the Washington Post poll. The president has the public on his side. Our nbc, the wall street journal poll shows a Different Number as you know. Says here, 57 favor path hood to citizenship for undocumented immigrants, 74 backing it, when they hear what the pathway entails there. Thats one number. Nbc the wall street journal says 48 oppose the president taking executive action versus 38 supporting him. Thats the number from our poll. Let me bring back mike. The dynamics, you cover the Supreme Court, you know the dynamics of the spreek court, the view many have of the court, regarding the health care decision. Now this decision that will divide the country potentially. If the court gets its hands on this case, there are issues of standing whether the house of representatives can represent itself and challenge the law on its own. Beyond that, if they reach the merits, by the time they go to the Supreme Court, several appeal processes, maybe the president is stepping out the door and could be on the way to another administration. In the absence of additional legislation, passing through congress this type of relief the president is planning, there might be the option of a court striking it down, which would mean all the groups happy about todays impending order might be very disappointed several years down the line should a court strike it down. As i say, before the statutory language, it points toward president ial discretion on this, but a court could say it is a matter of quality, not quantity when you reach 5 million, over 1. 5 million. Tamron, speaking of the Supreme Court, the Supreme Court ruled on a similar issue, the 2012 case, u. S. Versus arizona, from jan brewer, the court ruled he has broad executive authority. They laid precedent in favor of the president taking action. Thank you both for your time. Appreciate it, gentlemen.

We are following a developing story out much Florida State university this morning. Police are investigating why a shooter opened fire in the universitys main Library Early this morning, injuring three people. New video sent to us by a student shows the moments after a gunman burst into the crowded library which was packed with hundreds of students studying for final exams. In it, another student we see another student that may have been shot, holding his leg, saying he is bleeding. Oh, my god, are you okay . It is bleeding, it hurts. Okay. Oh, my god. So the gunman was shot and killed by Police Outside the library. One of the students that was shot is in critical condition, another in stable, a third treated at the scene and released.

Thank you for joining us. Hi, how are you doing. Im doing good. How are you . A little shaken up, but i think im doing pretty good. What can you tell me about the events that played out . It was very surreal. I left the i left strozier and checked out a couple of books from the library to do a research project, and as i leave, he go down the steps and the person behind me fires the gun, and very clearly a gun when this happened, but at the time i didnt really want to accept that a gun had gone off. I slow
