leonard town, fredericksburg and right southwest of warrenton. hanging on for about another three, maybe four hours. i wanted to open it up and show you the lake effect snows. keep your eye on that one little area coming off lake erie. because you can track it all the way down as it came into our area. starting up there about 1:00 a.m. by 10:30, north of ellicott city. this is the image i took earlier today on my way in. it was enough to produce a light coating on area roads. here's another shot of one of the parking lots. but this snow in fact made it all the way to ocean city. that's right. even ocean city around cambridge. areas around delaware getting some light snow. our temperatures very low, below freezing. 28 in warrenton right now. we've had wind gusts throughout the day. 35 and 37 miles per hour. they're going to start subsiding but it is still very, very windy. you might imagine that will have an effect on the temperatures

throughout the overnight. they'll be dropping to the single digits by tomorrow morning. flurries for about five, six, maybe 7:00 a.m. then our temperatures start heading down to 24 degrees by 11:00 p.m. with again, single digit windchills expected later tonight and early tomorrow morning. we'll have more on what you can expect for the rest of the week. it might put a smile on your face. >> looking forward to that. an air jet skidded off the runway in ohio and slid into the mud. this happened last night. no reports of injuries. everybody got off the plane safely. the plane was coming from st. petersburg, florida, but had problem making a turn off the runway. the faa is investigating this incident. here we go, the first

i guess i'm like single a, not aa or aaa. she is the author of the willpower instinct. she talks about how yoga kin crease your willpower by exercising your mind. so you're stretching this and everything else. >> you're supposed to work everything out. >> so you've got a little something we need to look out for. >> right. more showers for tomorrow morning. yep. but not the kind that we'll to have worry about on area roads because we're talking about meteor showers this time. not so bad. take a look at the graphic. this time we're talking about 60 to 100 per hour from the quadrantid meteor shower. for you few lonely souls that may be up that early, you should be able to get a pretty good viewing of these. set your camera to time lapse there. maybe you can get some pictures to us. the moon will set at 3:14. unlike some of the other meteor showers, this time i don't think

the moonlight will get in the way. 60 to 100 per hour. it could be even a few more than that. as far as what snow showers are still left around the area, you could see there are still a few coming through. right now around winchester through warrenton, around "friends," and leonardtown, maryland, more to the north. here's the future weather. we'll see the skies clear. there may be some spotty cover especially to the west around i-81. then more cloud cover by tomorrow afternoon. we'll start with a little bit of sunshine. then more clouds for the afternoon. it won't be as windy as today. the winds will be out of the northwest at 10 to 15 miles per hour. then thursday, i love the way thursday is looking. back to some sunshine around here. the sunshine through the area. and highs that will be getting into the mid 40s. so tomorrow morning, here we go.

20 to 21 degrees. it will be cold with windchill values in the single digits. there's a look at frederick by 3 degrees. then tomorrow morning, 7 degrees to 12 degrees in gaithersburg with a day that will be feeling like we're just under freezing. let's go ahead and take a look at the four-day forecast. 35 degrees. your high for tomorrow. a little breezy. 46 for thursday. and up to 56 degrees by saturday. the weekend, looking okay. we're going to have mostly cloudy skies on saturday. we may see a brief shower coming through early sunday morning. we'll watch that closely for some of the county's north and west. there is maybe a slight possibility there could be a little bit of mixed precip sunday morning. >> thanks. cyber security experts have a warning about that new mobile device you got for christmas. >> the number one target for hackers in the coming year. scott budman reports. >> according to silicon valley

device and that's cool but it is also dangerous. keep it safe this new year. because it's vulnerable from threats both real and virtual. >> the device we're hearing to keep from becoming aville, treat your mobile device like your home computer. >> you want to update your virus fighting software and beware of any e-mails, tweets or others that come from unfamiliar places. coming up, remember that infamous tiger mom who
