in boulder, colorado. cameras caught that incident, and the president took it in stride, laughed it off. and as if that weren't enough, he even brought up the incident during his speech. that poor girl is motorfied. >> she's lucky the secret service didn't take her out. you hope it's yogurt. >> she will have a story to tell for the rest of her life. >> we'll need to find out who she was. >> she'll be on some show. i'm hoping the "today" show. the shuttle "enterprise" will not be taking off this morning as delayed. nasa delayed the trip the to see new york because of weather. nasa hopes to fly "enterprise" out on friday on the back of that modified jet from dulles to jfk just like the shuttle "discovery" did last week. once it's in new york, a tugboat will move the "enterprise" to the intreadid museum on the -- intrepid museum on the west side of manhattan. >> i love that you see it on -- >> on the water. the river. gorgeous. let's check the forecast again. we've been complaining about this chilly weather, kind of making us grumpy. we're hoping for nicer days, tom -- >> you, grumpy? i'm shocked. yeah. really. this is really getting old. i mean, here we go again. another cold morning. look at this view, this should brighten your mood. >> that does. >> this should lower your irritability. golden sunlight skimming the trees of northwest d.c. on this wednesday morning. it's cold. counties in blue, a frost or freeze. dark blue counties, scattered frost, including culpeper, rappahannock, into fauquier and loudoun and frederick counties in maryland and farther west. and these areas in light blue, a hard freeze, central shenandoah valley, in western maryland. this is for another couple of hours even. temperatures are going to be near or below freezing. look how cold it is. even at prince george's county, charles, calvert, st. mary's, southern maryland, mid 30s as well as in montgomery, arlington, fairfax counties, most of virginia, at or below freezing as is much of west virginia. here's your day planner for this wednesday. you need the winter coat this morning. by your lunch hour, you can shed the coat. we'll be into the mid 60s by then. a blustery wind. we'll have lots of sun and peaking near 70 by mid-afternoon. a 35-degree jump from where we are now. sunset at 7:55. by then, back to the 60s. then we'll be down to the upper 40s by dawn on thursday. through the day tomorrow, we might get a morning shower. you'll need an umbrella. passing showers likely after that through midday. maybe even an afternoon thunderstorm. after that, we'll dry out a bit on friday. highs in the mid 60s. right now, there looks like a chance for rain for the weekend. now it looks like that may be on saturday afternoon and evening. a chilly day, too. highs only around 60. and then drying out sunday is the way it looks now. stay tuned, though. there's quite a bit of uncertainty it the weekend that could change. first part of next week, partly cloudy monday, tuesday. highs near 70 again, which is about the average high this time of year. and matt has our look at traffic now. good morning. >> reporter: and a good morning. at this point looking at 270. you are going to see congestion as you head south of 70, pretty much all the way down now. 31 miles per hour, the green valley stretch. further down toward falls road, we've got a lot of congestion. not too bad at this point as you approach the beltway. once you're on the top side beltway, you've got a pretty heavy pace from 95 all the way toward 270. running at about 18 minutes on average. 32 miles per hour. looks like some late lifting construction there northbound on the 495 stretch on thewide. you're going to see -- the pesticide. you're going to see with the left lane partially blocked. arrows telling everybody to get to the right. that's going to keep things thick there. back to you. >> thank you. quick work overnight by metro. no delays on the blue and orange lines. less than 12 hours after a car derailed. this happened during the tail end of the evening rush just after 7:00 at the rosslyn station. news4's tracee wilkins there live with overnight developments. >> reporter: good morning. it was a mess yesterday evening. and plenty of commuters were thinking that the same thing may happen today. as you said, the good news is both the blue and orange lines are up and running. let me show you what it looked like yesterday. 7:00 p.m., they had a train derail here. happened with a franconia/springfield blue line train as it was leaving the rosslyn station. they say one set of the wheels on the first car came off of the track. metro's calling this a minor derailment because they were able to get the train back on to the tracks, although they had to single track to get passengers out of the station yesterday evening. now, passengers were complaining yesterday about a lack of communication again. and metro officials not telling them what to expect next for a long period of time. we talked with metro spokesperson dan steffel about that. here's his explanation. >> we had power down on both tracks for a brief period of time. that effectively meant services suspended through the rosslyn station. shortly thereafter, we realized that it was safe to continue single tracking trains through the station. that's when the message changed to single tracking with delays. there will be a little bit of fluidity in the beginning stages of any incident like this. >> reporter: again, the track has been fixed. they havealso -- also tested it. they're not expecting issues for commuters. they're working to try and figure out exactly why this derailment happened. tracee wilkins reporting live from rosslyn. news4. >> thank you. in just about 12 hours, the caps will be taking the ice for the most important game of the season. players are in boston this morning getting ready for the decisive winner-take-all game seven. it

outlook. >> ah. >> yes, today near 70. that should improve your mood. blustery wind, though. lots of sun and rain tomorrow. that should wash the pollen out of the air again. mild day, maybe afternoon storms and maybe a little more rain over the weekend saturday afternoon. that's the way it looks. >> thank you, tom. let's check in with matt to get a look at traffic. >> reporter: we're looking at late delays out there on 66 right around prince william parkway. 16 miles per hour at this point. and there's a live shot at all that slow going. back to you. >> thank you. and that is "news4 today."
