Will snow be making a comeback in the Northeast next week?

AccuWeather

A storm system could bring snow to the Northeast early next week-or it could go out to sea over the Southeast. AccuWeather's Bernie Rayno explains.

00:00 Well, snow could be returning in the forecast for the Northeast as we head into next week.

00:05 So let's send it over to Bernie Rayno who's got a look ahead.

00:08 Bernie.

00:09 You know, while there's no sign of winter right now, Mid-Atlantic and Northeast, watch

00:12 out early next week.

00:14 Some ingredients coming together for the potential for some snow.

00:17 Now, let's talk about where the storm is that may produce this snow.

00:21 There it is.

00:22 This is Alaska.

00:23 Here's Anchorage.

00:24 So you're talking about the Southwest Aleutian Islands here.

00:27 That's where the energy is.

00:28 Now let's track it.

00:29 We've got plenty of time to track this system.

00:31 It's going to be moving north across Alaska, then come across British Columbia, and then

00:36 by Friday, where is it?

00:37 Across the Northwest.

00:38 A lot of energy with this.

00:40 You can see that, the yellow and orange shading.

00:41 Now watch what happens.

00:43 This continues around the bend, and then it sets up a very interesting weather pattern

00:47 as we get into Sunday evening.

00:49 It's what we call a split flow.

00:51 What's a split flow?

00:52 Two branches of the jet stream.

00:54 A northern branch and a southern branch.

00:57 Now this is how this is going to work.

00:58 The northern branch, well the southern branch is the storm.

01:01 That's where you have all the moisture.

01:03 So this is where you have the storm.

01:05 The northern branch is going to do two things.

01:07 It's going to deliver cold air on the northern side of the storm, because remember, we don't

01:11 have any.

01:12 And it's also going to steer this storm.

01:14 Now, if this northern branch of the jet stream moves as quick or quicker than the southern

01:19 branch, it'll drive the storm out to sea.

01:22 It'll keep it off to the south.

01:24 There will be no snow with it.

01:25 Now, if this southern branch of energy moves out ahead of the northern branch, then it

01:31 gets guided to the northeast.

01:33 And then you're talking about the possibility of snow.

01:36 So again, this is what we're watching for early next week, Monday into Tuesday.

01:39 Again, that northern branch, if it says moving as fast or faster than the actual storm, then

01:45 it gets driven into the south and out to sea.

01:47 But if that storm moves a little quicker than the northern branch, it gets guided to the

01:51 northeast.

01:52 Here comes the cold air.

01:53 And voila, you're talking about some snow.

01:56 We have to watch that.

01:57 Even around Washington, D.C., Baltimore, you have to be concerned.

01:59 But certainly across parts of Pennsylvania and New England, you know I'm going to keep

02:03 an eye on it.
