Three things to know for the weather across the US for the final week of October

Around the time of Halloween, a nor'easter could slam the East Coast with coastal flooding and heavy rain.

00:00We're going to take a look at the extended forecast with three big headlines for next week.

00:05Three things to know for next week.

00:06There will be a cool pattern in place across the south and the eastern U.S.

00:10It's going to still be stormy in the northwest at times.

00:12We get a little break early in the week after some Sunday snow in the mountains

00:15and heavy rain all weekend at times, at least into the lower elevations.

00:20But one real compelling story about next week will be a nor'easter threat mid to late week.

00:26This is going to be perhaps energized by the coastal storm.

00:31You can see we're dealing with a big dip in the jet stream.

00:33Here comes a big dip coming down from the northern plains all the way down to the Gulf Coast

00:38with energy, spokes of energy, rotating around the base of that.

00:42And in this particular example, you can see that Melissa is offshore.

00:47And this would be more of a disconnected solution.

00:49But there are other computer models that actually hug Melissa a little closer to the coast,

00:53and that would wrap into the energy of this east coast storm.

00:57So that's something we need to keep an eye on.

00:58Regardless of if Melissa interacts with this east coast trough

01:02or if the trough before it scoots Melissa out to sea with a little less interaction,

01:07there will be a very impactful event here with chilly flow in place,

01:12dip in the jet stream, surface low pressure strengthening next week.

01:15And that's going to bring some drenching rain to the mid-Atlantic,

01:18and that expands north.

01:20Tuesday, it's still kind of in its early stages.

01:22This pulls north Wednesday and Thursday, and here's the red zone,

01:25where we're concerned about impacts involving coastal flooding,

01:29significant rain, significant onshore wind.

01:32And remember, these dunes in many areas along the Jersey Shore

01:36all the way down to the Outer Banks have been greatly compromised by Aaron

01:40and, again, by Imelda, where a storm, again, the tropical rain and windstorm

01:45that followed that, again, we've had a lot of problems here.

01:48And this could be yet another big flood producer.
