>> pretty much, i'll tell you right now, i'm not expecting much snow at all next year. >> out there right now, tempature on the -- well, we'll call it cool side. it's really not all that bad. however, dew points are up. that means the moisture in the also molt fear helps to make it cooler. winds out of the north at about 10 miles per hour. that little bit of wind helps make it cooler. >> we'll be watching a little system. i do mean a very little system. let's widen it out here. here's the system that came through last night. it's not nearly as powerful when it came across our region. it just gained strength right off the coast. now, it is a monster storm. look at that thing. a classic,om

still close to the boston area right off the coast. this is the next storm that we're watching. look how small this is. we'll continue to provide us with some cloud cover. maybe some sun early. and then, around 2:00, call it mostly cloudy. through 11:00, we're fine. watch what happens here. around 3:00 in the morning, we see that band come through. and it's snow to the north and rain down to the south. so even in d.c., we could see a little snow. don't be surprised if you're walking around at 3:00 a.m., don't know why, but if you're walking around at 3:00 a.m., you may see some snow showers. by 8:00 in the morning, most of it is out of here. i'm not expecting any accumulation out of this. and, by friday or sunday afternoon, we're looking at s

sunshine and a much nicer day. most of sunday is going to be fine. tomorrow, still cool. not bad. 49 fredericksburg, 46 in leesburg. as we move on through the day tomorrow, this weekend looking good for just about everything. exercise, just cool. hiking, biking, wear extra layers. skiing, great. everybody saw snow from this last night. rockville, out towards pentagon city. all looking good for that, too. it's going to be on the low side. and then look at the next couple of days. 48 on sunday. only a 48% chance of a shower early east of i-95. and then 60 on monday, 70 on tuesday, 73 on wednesday, 75 on thursday. we will see a chance for showers on thursday. that will leave us with a little cooler weather on friday. but cooler at 68 is not bad at all. >> we need some warmer weather. >> i'll do anything for that three days in the 70s.

>> busy night for the locals. the wizards try to take down the cavs. sports is next, but, first, here's jimmy.

thank you so much. did you say honey? hey, try some? mmm that is tasty. is it real? of course... are you? nope animated you know i'm always looking for real honey for honey nut cheerios well you've come to the right place. great, mind if i have another taste? not at all mmm you're all right bud? never better i don't know if he likes that. yeah part of the complete breakfast a busy night

but as doug said before the break, sure as heck wasn't a good one. breaking down the wiz and the caps. >> there was a loot of promise for tonight. the caps had been one of the best regular-season teams in the afl for post season success, that's a different story. the caps face a team that eliminated them last year. looking for a third straight win over new york. down to the second, put on the attack. mike richards throws a couple on net and then everything goes crazy. a couple of whacks at it originally ruled no goal. hard to tell. calm for the review. caps haven't lost this season. late in the period, caps are rushing in, no doubt about this one. shifter period. caps get carely with the puck.

and derrick makes them pay. turns out to be the game winner. a rare loss for the caps, 3-2. >> every time you're playing the rangers, you've got to come out with your best. and, you know, it's a fun game to be apart of. came up a little short. second and third period, it's how we've got to play. >> you doint want to give up a goal at the end of the period. we gave it up first shift. worth the price of admission. he gets the steal. yeah. he takes off from the concession stands. >>

>>. >> timmy has the oop. wizards then decide that guarding lebron is optional. cavs go on a 17-6 run. third quarter, john wahl and company. gets the bucket and foul. wahl remained down for a while. he did continue to play finishing with 17 points, 8 rebounds and 7 assists. but the wizards get blown out 108-83. spring training in full swing next. visiting division rival miami. not sure of his role this upcoming season. solo shot puts the nats on the board. first start again. limited work. but the nats lose 6-5. red skins locked

now, they're getting the rest of their roster. the line backer compton all right, the wiz and the caps won't be able to think about tonight's losses for too long. the caps are in boston, the wizards host the pacers. guys, let's hope for a better

i do everything on the internet. but, it's kind of slow. my friends say i should get fios because it's the fastest. i just downloaded 600 photos in 60 seconds. that's seriously better. (husband) we're out of 2%! i wonder what else could be better around here? (husband) i heard that. switching to better internet is now easier than ever. only fios has the fastest internet available, with uploads up to 5x faster than cable. get 100 meg upload and download speeds. plus tv and phone for just $69.99 a month online with no annual contract. switch to better. switch to fios.

there was a lot of sweat and a few tears downtown tonight. but it was all for a good cause. >> every penny from the fundraiser helps research ple moral yal sloan kettering. nearly a thousand people are r participating through the weekend. scott kelly says his skins sometimes feels like it's burning now that he's back on earth. that's what a year of being weightless will do to you. something as simple as sitting down will take adjustment. he's already back to his original height after gaining an inch or so in zero gravity because of all of the weight taking on his spine. that's going to do it for us. my wife is due tonight.

maybe i'll be back monday. >> good luck.
