meteorologist chuck bell is in storm center 4. chuck? >> good evening, chris. good evening, everybody. as advertised, the light rain showers have moved into the area. primarily after sun down this evening. and the good news is i think most will be out of here before your monday morning commute back to work and school. temperatures remain on the mild side right now. mid to upper 50s around town. mid-60s in the mountains of west virginia. plenty of light to at times moderate rain moving south into the area coming down out of pennsylvania. the back end of the rain is already pulling through pittsburgh, pennsylvania, and as a result, i have a great amount of confidence that we will not have to worry about anything in the way of a sloppy morning commute. showers racing south. rain gone by the morning rush. cool monday breezes. but with sunshine. what about the rest of the week ahead? i'll give you that in the seven-day coming up, chris. >> thanks, chuck. former president bill clinton took his global initiative through the streets of d.c. today. he and his daughter chelsea joined a group of college students in sprucing up a northeast neighborhood. looking for strangers in need, they did yard work, house mate nance and anything else they could. the global initiative challenges students to find new approaches to improving the community. >> any nation is only as strong as its people and its neighborhoods on its streets and its schools from the grass roots up. >> it's terrific. both for the students who come from more than 300 colleges who really are here motivated by service that they are already doing. >> chelsea clinton is an nbc news special correspondent. now over the years, the event has brought in millions of dollars in commitments for global initiatives. it's do or die for any gop candidate not named mitt romney this week. primaries are being held in maryland, d.c. and wisconsin on tuesday. newt gingrich will speak in maryland at the frederick motor company tomorrow morning and then head to hood college in the afternoon. and while wisconsin could ice the nomination for mitt romney, no candidate is bowing out of the race. brian mooar reports. >> reporter: mitt romney is hoping a win in wisconsin's primary will bring an end to his rough road to the nomination. >> and on tuesday, we're going to pick the next president of the united states. >> reporter: house budget committee chairman paul ryan is endorsing romney. so is freshman tea party senator ron johnson. >> i totally believe he is committed to saving america. >> reporter: and with the republican establishment and prominent tea party members lining up behind him, romney is looking ahead. >> this is an election about what america is going to be. >> reporter: romney has a commanding lead in delegates and rick santorum is clearly tired of hearing about it. >> if romney gets the 1144 delegates before -- >> i'm not talking about this anymore. we're just focused on doing well here in wisconsin. >> reporter: santorum is shrugging off romney's endorsements and laughing off talk that romney is about to lock up the nomination. >> i'm encouraged by all of this. i think it shows that the establishment is getting nervous. >> reporter: but santorum has reason to be concerned too. tuesday is his last chance to win a big prize in the midwest before the gop race heads to his home state of pennsylvania. brian mooar, nbc news, washington. mitt romney got a big april fools' joke from his campaign staff in milwaukee today. he was getting ready to give a speech at a campaign event. wisconsin congressman paul ryan went out and introduced romney and, well, here's what happened. >> ron johnson and governor mitt romney, the next president of the united states. >> later the republican presidential candidate told the real crowd about the joke. romney says he forgives his staff but he'll remember it for the future. still ahead tonight -- riots at the university of kentucky after its big win over louisville. how police are trying to stop it from happening again tomorrow. your cell phone is wireless, so why do you plug it in to charge it? we'll tell you how to cut the cord. still sore about not winning the lottery? why $640 million doesn't go as far as you may think. and coming up tonight on "sports final," there's drama on ice. why a couple of head coaches had to be held back in pittsburgh.

towson university will remember two students who died within hours of each other. ryan bailey and 27-year-old timothy coyer. bailey was hit by a car near washington avenue and york road early saturday morning. coyer, an iraq war veteran, was found dead in his apartment yesterday by his roommates. investigators say he died of cardiac arrest but the exact cause of his death still has not been determined. several hundred police will be on hand at the university of kentucky for tomorrow's ncaa championship basketball game. they are hoping to prevent the rioting like this that you see. it happened last night near the campus. students took to the streets after beating louisville in the semifinals. cars were overturned and more than 50 fires were set. some kentucky players are taking to twitter to tell fans to behave. okay. this will make you either feel really bad if you are one of the three lucky mega millions winners or maybe a little bit better if you weren't lucky enough to win like most of us. it turns out that $640 million really isn't all it's cracked up to be. here's a little lesson in subtra subtraction. you're splitting the pot three ways. $640 million. so your share is $150 million apiece. well, of course, then you have federal and state taxes. chop off another $50 million. that leaves you with $100 million. still, pretty good. i will grant you. you you will go bankrupt if you splurge and try to buy certain things that everybody dreamed about when they were buying the lottery tickets. a gulf jet will cost you $64 million. plus pilot and storage fees and maintenance. a private island to fly that jet to, $25 million. even if you won the entire jackpot, you would only have about $300 million left. now it turns out that's a salary of $7 million a year. sounds pretty good, but if you were hoping to be one of the 40 richest americans, think again. number 40 on that list takes in more than $1 billion a year. so if you think about it, you're left with small change. well, most of us can't go anywhere without our cell phones or electronic devices. but their convenience is limited by one thing. a cord. they all have to be plugged in quite often to keep running. now that could soon change. a california microchip company has come up with a wireless charging device. you just drop your phone on top of it and it gives you juice much faster than a plug. >> the idea would be these coils are charging surfaces would be built into public areas for waiting rooms, fast food restaurants, hotels. that sort of thing. >> the chip company idt hopes to start selling the wireless chargers to the public by the year 2014. well, political junkies and movie buffs alike got a unique chance to be seen in a new tv series from netflix. central casting held an open casting call in southeast for extra in the original series "house of cards." the movie will be shooting in baltimore and the district. the much-anticipated political thriller starring kevin spacey explores the british political scene toward the end of the margaret thatcher era. people we talked to today say they're excited for the chance to be part of the series. >> it's fun. you get to meet interesting people. you get to see yourself in the movies. sometimes. sometimes not. >> house of cards is the first originally produced series by netflix. they are scheduled to begin shooting in april. >> they couldn't find a nicer place to shoot it than right around here. beautiful stuff. >> and now tonight, some people got more rain than others. >> yes, but nobody got a whole lot of rain. there's been no concern whatsoever for any kind of flash flooding or severe weather. that's welcome news. and most everybody if you saw the rain, about 0.1 inch of rain. some of the lucky winners have had almost a quarter of an inch of rain. just enough, we hope to get the pollen count back down to within a manageable range in time for your monday morning commute. but with more dry weather than wet weather ahead this week, expect the pollen count to be fierce once again as we get towards the middle and later half of the upcoming work and schoolweek. outside, it is cloudy. there is still a little bit of light rain coming down at national airport. but it's a mild one. 58 degrees with the drizzle out there right now. dew points in the mid to upper 40s. if it were raining harder, the temperature and the dew point would be closer together. that's an indication of the fact it's light rain that's out there right now. barely a breeze out there right now. winds generally out of the east and southeast at less than 5 miles per hour. temperatures are mild. mid to upper 50s right now. high temperatures tomorrow, probably not more than a couple degrees warmer than that as behind the cold front, cooler air starts to move in. here's your monday planner. partly to mostly cloudy. temperatures in the 40s first thing in the morning. we'll quickly go over to a bright, full, mostly sunny part of the day. temperatures up to 60 degrees by after lunch nm and then holding in the upper 50s and low 60s for much of the afternoon. thanks to a north breeze tomorrow. north winds 10 to 20 miles per hour or higher for much of the afternoon. so a breezy monday afternoon coming our way. here's storm 4 radar. most of the moderate light to moderate rain now, fairfax county, loudoun, northern fauquier county. they're drifting southbound. it's going to be kind of wet for the next couple of hours. interstate 66, 95, the capital beltway all getting in on the light rain for now. these showers are pushing southbound. so you folks in fredericks burg where it hasn't rained yet. there are light rain showers coming your way fairly shortly. the back end of the rain is starting to show up near southwestern pennsylvania. so the little bit of rain we have to go through here on average, 0.1 to 0.25 inch of rain. cool dry air up to our north and west. that's what we get to enjoy for tomorrow afternoon. and a chilly start coming up on tuesday morning. umbrellas at the ready if you are going out for late night drives. by early morning, back to work and school. dry weather for the monday morning commute. monday is looking like a beautiful day. plenty of sunshine. but again, that north wind will make it feel on the chilly side. especially if you are in the shade. then high pressure settles on in. a very cool to almost cold start on tuesday morning. but tuesday afternoon, bright sunshine returns and that puts temperatures back near 70. so overnight tonight, showers ending before sunrise. otherwise, chilly. start off temperatures in the 40s. tomorrow afternoon, bright and sunny. but breezy. highs tomorrow, upper 50s and low 60s. a look down the road through the week ahead. tomorrow the breeziest and probably one of the cooler days of the week. tuesday looks great. wednesday, a chance of a sprinkle or two first thing in the morning ahead of the next cool front which brings in chillier air for thursday, friday. all is right with the world. sunny and back near 70 again. >> it feels like it's been an extended spring. >> we missed winter entirely. >> dodged that bullet. thank you, chuck. coming up tonight -- it was called the million mustache march. what these protesters were demanding from the government. and in sports, the wizards head north, but would coming in to tonight's game, the wizards were, what, one win in a row? >> yeah. they were trying to get two in a row. they'd only won two in a row once this season. so this was -- this was rare air, i guess. >> too late to start talking about next season? >> no, it's not. >> by now you know that wizards rookie chris singleton did not win mega millions after spending 10 grand on tickets. the wizard would certainly like to win the nba draft lottery next month. but even if they don't get the first pick, just being in the top five will certainly have people shouting, jackpot! three of the top five projected picks will be on display monday night in the national championship. anthony davis, michael kid-gilchrist and thomas robinson. vesly was the top pick last year. and they had the awesome camouflage jerseys. second quarter, jordan crawford up to john wall. that's nice. wall had 13 points, 11 assists. wizards down four at half. third quarter, crawford misses but veseley, one-handed put-back. the rookie with ten points in the game. wizards within two. just over a minute to play. three-point game. toronto's derosen, no good. but amir johnson. they're on the cleanup. wizards lose, 99-92. their record drops to 12-40. ouch. talking baseball. nats/cardinals. gio gonzalez on the mound. gets carlos belt ran swinging. gonzalez strikes out seven over five innings giving up just one run. top nine, tied at one. derosa facing jason mott. base goc rigknock to right. here comes espinoza. looks like he's tagged out but he's called safe. the nats win and play the red sox in florida tomorrow and then another exhibition against boston in d.c. on tuesday. orioles taking on the rays. chen on the mound for baltimore. james shields on the hill for tampa bay. os down 1-0 until j.j. hardy gets a hold of this one. shot to left. the first two of solo home runs in the game for hardy. game tied at one. top four, chen in some trouble here facing desmond jennings with the bases loaded. and you so don't want to go there. right down the middle. jennings crushes it to left for a grand slam. he finished with six rbis. the orioles lose, 8-5, in their grapefruit league finale. coming up on "sports final," things get crazy in pittsburgh when the flyers and penguins' coaches are the ones fighting. mike wise joins us in studio. plus how one local high school athlete uses an embarrassing
