happen with this one. i am not impressed with this storm at all. that's good news for you if you didn't want a whole lot. let's show you what is going on right now at the airport. temperatures well above freezing. 39 degrees right now. close to 40. and we are still dealing with some light rain across the region. winds out of the southeast right now at 7 miles per hour. here is the advisories. again, winter weather advisory went into effect at 10:00 all the way through midnight tomorrow. that's a little bit late i think. but it's all good. around the d.c. metro area, prince george's, lower montgomery, and points to the west. now winter storm warning in effect for northern montgomery, howard county, towards indianapolis, the frederick, maryland and points to the north and east. this is the area that will see the most snow. will they hit the winter storm advisory criteria? maybe not. we have the snow now, already starting to see the changeover. d.c. the changeover comes around 1:00. here is snow going on right now. down around the leesburg area. back towards bluemont.

you'll see it towards mt. airy fairly soon and over towards jefferson county. especially along the blue ridge. any areas of elevation, you are going to start off with snow. but most of us seeing the rain changing over to snow. we'll continue to see that right on through the night tonight. take a look at the storm. it's very disorganized. actually, it's just a couple of pieces of energy here. you've got one piece of energy that is moving through right now. you've got this next piece of energy way back off to the west. this one is going to be moving our way. and i think right now the heaviest of this may stay just to the north. that's why the bulls-eye is up there around howard county, around columbia, maryland, around baltimore. and take a look at the numbers. we're so warm. 37 manassas. 36 in gaithersburg. now as the snow comes down, it will bring the temperatures down a little bit. but i think most areas remain buena vista freezing. because of that, i'm not expecting too many problems on the road. especially the main roads, unless we get some really heavy snow. that could happen with some banding that is developing. but here is the brand-new

computer model, 3:00 a.m. notice d.c. still dealing with the rain-snow line around the d.c. metro area with snow up to the north and east. buy early tomorrow morning, d.c., rain-snow line. south all rain. to the north it's all snow. frederick, hagerstown, back towards the leesburg and ashburn region. those are the areas that have the best chance for snow. again, more snow to the north during the late morning hours of d.c., maybe going back over to rain. and continuing to watch this play out during the day tomorrow. so new snowfall map. what are we expecting? i've lowered it down to one to two. i think that's extremely generous for areas like d.c. maybe downtown not getting much at all out of this. i'm not expecting much there. fairfax maybe an inch, 2a at the very most. 2 to 5 towards frederick, mt. airy, columbia. would not be surprised to see some areas a little above this but they would be few and far between. not a lot going on tomorrow. an impact forecast on the

moderate. rain, snow likely with the umbrellas. need the boots during the day too. the temperatures the next few days. 38 on tomorrow and wednesday. a few flurries on wednesday. and then here comes the cold. we're talking extreme cold. highs in the 20s three out of the next seven days. windchills on thursday and saturday only between 10 and say 15 degrees. some areas could see temperatures close to zero early on sunday morning. that's the night after valentine's. >> okay. thanks, doug. coming up, a super sophomore helps georgetown make a statement. >> first here is jimmy fallon. >> thank you, doreen and jim and everyone in washington, d.c. ben stiller is my guest tonight. plus we have

the final score 94-86 ohio state. on the men's side, maryland moving up in the rankings again. checking this week at number two. the terps coming off a huge win against 18th ranked purdue on saturday. second time this season maryland has been ranked as high. >> we have to talk about it. it's different. i think number two we don't have to. i'm proud of our guys because it's february, whatever. we play 24 games and we're number 22 in the country. and we got a lot on our plate. we've been able to handle it. >> right now to a certain extent we can care less. we're just trying to get better each and every day in practice and every game that we have. we just want to be one of the teams that are able to compete at the end of the year. elsewhere, after peyton manning raised his second lombardi trophy, he went to the happiest place on earth, disneyland. there you go. peyton manning was there today,
