temperature move up and up. 54 in washington, 61 in fredricksburg, 55 in manassas. you can see a big spread, especially as you head north for i-81. we're going 50s pretty much for everybody. if you're south, obviously, you get a little bit more warmth. this is the rain that will be moving into our area. around i-81 just around the noon area. it will continue to move east to southern maryland around 2:00 or 3:00. we'll time it out hour by hour in just a few minutes. crews are making some progress fixing a water main break in silver spring. chopper 4 was just over it. a couple lanes were shut down this morning and it was entirely closed at one point. the broken pipe is 12 inches and 88 years old. crews dug a big hole out of the street to fix that break. melissa mollet will be coming up

placed on administrative duty as is common practice in an investigation such as this. now, it is ironic. we are told about two months ago in november, there was a police-involved shooting, a fatality, just about a block away from here on 53rd and dix street. in that case police encountered a man way knife and police say another sharp-edged weapon. that person was shot and killed as well. again, this investigation continues here. police and people who live around here actually tell me there is often a police car posted at this intersection. we don't know if the officer who was there was the one who was involved in this. all of that is part of the investigation which is, indeed, ongoing. we're live here in northeast. derrick ward, news4. back to you. >> thank you, derrick. in northwest washington someone was stabbed to death overnight. d.c. police say two men were stabbed on elf street a few blocks from farrugut square. police were investigating the area around the barcode.

one man was killed, another one is in the hospital right now. officers say two stepbrothers had an argument. it happened right across the street from the police station on plaza street. officers say a woman ran into the lobby just after midnight saying a man had been stabbed. one of the stepbrothers later died at the hospital. and turning to decision 2016 now. here are four things you should know ahead of the iowa caucuses tonight. voter turnout could dramatically impact the success of certain campaigns. both donald trump and bernie sanders are counting on support from young, first-time voters. if they don't show, that could affect the results. there are 30 delegates available for republicans and 44 delegates available for democratic candidates. democrats must have 15% support from a caucus to earn a delegate, and we may not know the winners before you go to bed tonight. be sure to check your nbc washington app in the morning and watch our coverage live from

right now last-minute appeals ahead of the iowa caucuses. here's where democrats stand among iowans according to the des moines register's poll. hillary clinton and bernie sanders are essentially tied. o'malley falls way behind. now to the republicans, donald trump leads with 28%, ted cruz follows with 23%, and then there's marco rubio with 15%. now let's get the latest from

our aaron gilchrist covering the caucuses from des moines. aaron? >> we are in the final hours before the iowa caucuses now, just a couple hours left before the voters in this state will gather in those meeting areas in 17 precincts around the state. candidates still today have been chris-crossing the state trying to make final pushes to get people to caucus for them. turnout is going to be key at 7:00 here in iowa. it will be the time whether we see more people show up, whether we see first-time voters or more younger voters who might turn out today. that would be a boost for bernie sanders and for donald trump, for that matter, but it's all going to be left to see what happens tonight in terms of thaç turnout. then the practice, actually, for caucusing is different for republicans than it is for democrats. a little more involved for democrats, but surrogates, for candidates to come to those meetings and make a final pitch for the group.

then neighbors will get together and have a conversation, try to convince each other to support one candidate or another. at the end of the night we'll see who comes out on top. we'll have numbers an hour or so after the vote for the republicans. then here at the media center we'll see those numbers roll in, and we will know who is going to be the candidate that the folks here in iowa think should be the nominee for president for their individual parties. that's the latest here from des moines. i'm aaron gilchrist, news4. >> we'll be monitoring that for you from des moines. be sure to download the app to be the first to learn about the new developments. lauren, snow in iowa, right? >> yeah, a little bit of snow in iowa. nothing here, though, but that's that main system moving through the northwest. it's going to be here on wednesday. it's warm for us on wednesday because we'll have a surge of warm air, in fact, maybe record-breaking temperatures. our record that day is 65, i believe, set back in 1927, 1933

we have a breaking news update on that officer-involved shooting in northeast d.c. we just learned that the weapon of the person shot and killed by the officer, that weapon was found on the scene. it was a bb gun. this happened at the 53 -- at the intersection of 53rd and clay terrace. police saying the officer tried to stop the individual which followed with a pursuit and then a struggle, and it was during that struggle that they say the person showed what was believed to be a firearm, and as i mentioned, we just learned that turned out to be a bb gun. police saying that an investigation is still under way. back to you. wssc just wrapped up repairs of that big water main break in silver spring. as we just heard from crews, they have a big hole in the middle of university boulevard to fix the pipe. it's 88 years old. traffic moving normally on university. all lanes were shut down earlier this morning. it was pretty nasty. barbara? today is a huge day in politics with the iowa caucuses taking place.

campaigning, barbara. but guess what? not everyone participates. in fact, most people don't. the biggest turnout they had back in 2008, only one in six iowans participated in that caucus. that was the first year president obama was elected. >> well, it should be interesting to see what happens tonight, tracie. thank you so much and i hope you're having a good time. news4's aaron gilchrist is also in iowa today. look for updates from him on news4 at 5:00 this afternoon. cleanup after deadly storms in southern california. high winds knocked down a tree that fell across four lanes, crushing a small sedan and the driver. the national weather service says wind gusts topped 115 miles an hour outside san diego. up the coast, winter weather might be to blame for a 29-vehicle crash. look at that. more than two dozen cars and four tractor-trailers collided last night near the california-nevada border. no serious injuries there.

heart month starts today and it's all about raising awareness about the nation's top killer, which is heart disease. even though exercise we know reduces the risk of the disease, erika edwards reports some of us just don't get enough. >> a body at rest tends to stay at rest, said sir isaac newton. that tends to lessen the risk for heart disease. a new survey from cardiologists at the cleveland clinic finds 40% of us are not meeting the minimum recommendation for exercise. 30 minutes of five days a week of walking, biking goes a long way to helping blood pressure.wg fitness experts say start small and stay realistic. >> don't expect to lose 20 pounds in that first month. don't expect to go to every class five days a week right in a row.

>> reporter: just as exercise can help prevent heart problems, it's equally important for people already living with heart disease. doctors say they should be getting just as much physical activity as anybody else. >> the one caveat i would say to that is they should build an exercise program with a professional. so with their cardiologist or with their sports cardiologist. >> reporter: if you have those days that are impossible to work in a workout, don't take it sitting down. studies have shown simply standing for two hours a day can risk heart disease risk by 10%. erika edwards, nbc news. in some more news for your health this morning, apparently talking beats out texting when it comes to emotional well-being. during a stress exercise, researchers learned that women who received face-to-face support responded in a positive manner compared to support from text messages. it also helps pre-teens better understand non-verbal emotional
