WINTER STORM FORECAST: New details on snow, ice storm moving across US

We'll probably expect to hear from some schools over the next day or two about Monday because we're going to get hammered Sunday, right? I'm thinking Monday is going to be a snow day for most school kids across the region because Sunday is going to be a very active day. We've issued an active alert because we're looking at an all-day event. The snow develops before dawn. It turns very heavy into midday, changing to sweet and freezing rain in the afternoon for I-95 and areas south and east. So we'll still get the precipitation, but it changes in its form, and this is likely the biggest storm in about a decade. Philadelphia, we're calling for 8 to 10 inches before you get that changeover to sweet and freezing rain. So the impact scale, you can see, if you want to beat it, maybe really early in the morning around 5 o'clock, it will be snowing, but it's going to be on the light side. But then we have a 12-hour period between 8 a.m. and 8 p.m. where the impact scale is high because we're not going to get any period of dry weather. But again, it will be transitioning in many areas from the snow to the ice. So future trackers showing 8 o'clock in the morning, temperatures generally in the teens, inland areas, and we've got a heavy thump of snow, especially south of Philadelphia. As we head through the day, we start to see this ice line, that sleet, start to move up from the south as that coastal low takes over and the wind shifts off the ocean. So what this does, it pulls in warmer air higher in the atmosphere, changing that snow over to sleet, which you see in pink, along I-95 by the evening. And we've got freezing rain and rain across the shore. Now, areas in the far northwest will stay snow the longest. But even in the Lehigh Valley, I think late at night you could get some sleet mixing in. By midnight, everything starts to wind down. Monday, we have some lingering snow showers. But really, the accumulation will be on Sunday. So we're looking at 10 to 14 inches north and west of Philadelphia. I think the bullseye probably across the Poconos where they don't get any mixing at all. The I-95 corridor into interior South Jersey, northern Delaware will get that mixing over with sleet, maybe some freezing rain at the end. So that limits the snowfall amounts. But still, we're talking about a lot of snow. 8 to 10 inches, we have a band of 6 to 8 from Manahawk and Millville to Dover. And then Atlantic County right near the shore in Cape May County, this is where you'll probably see the less snow, 3 to 6 inches before that change over to sleet, freezing rain, and eventually changing all over to rain there. So a lot of that will be washed away. Currently, temperatures still really mild in the city, 43. Allentown, 32. Millville's dropped down to 25 degrees. This is the Arctic front that'll be pushing through tomorrow. That opens the door for very cold air. Tomorrow, temperatures, though, will be feasible. Low 40s generally, north and west temperatures in the 30s. The winds pick up with that front, and then we have a cold weather advisory for Saturday. Wind chills start below zero, and they only climb into the teens. So it'll be dry on Saturday, but it will be dangerously cold. The exclusive active weather 7-day forecast for your Friday. Blustery winds as that front kicks through that high, 41 degrees. Wind chills, though, dropping with winds gusting up to about 30 miles an hour. Saturday, 20 degrees. Wind chills in the single digits. Sunday, we have the active alert. Please stay off the roads. Heavy snow transitioning to some sleet and freezing rain, 23 degrees. And then there is no melting going on. Tuesday, Wednesday, and Thursday, temperatures stuck well below freezing, only in the 20s. So when we get the snow, we get that glaze of ice over it. You can't depend on Mother Nature to melt it. You're going to have to do a lot of shoveling. And if you have trouble, find that teenage kid in your neighborhood. Get him to do it. And, of course, Karen will have an update tomorrow morning. Yeah, we like the number six around here, but to say it's been six years since we've seen a storm this big is... It's been ten years, actually. Oh, I thought it was six. It's 2016. Ten years. I'll help you with a map during the commercial break. I got a headache. It's okay. Thanks, Seth.
