00:00When we have long-range weather forecast questions, we turn to the crystal ball.

00:05Joe Lumberg and Joe, we've got a loaded pattern across most of the north-central, north-eastern U.S.

00:11Yeah, we really do. It's just an active storm pattern, if you will, going forward.

00:16And part of the three things to know, not just next week, really, I want to focus on late next week,

00:21is the period from December 5th through the 10th, so we're talking really the end of next week

00:25through the beginning of the following week, cold is going to dominate from the northern plains to the northeast.

00:30There'll be a series of storms that'll come through the pattern.

00:32I think the biggest one that could affect the mid-Atlantic and northeast is probably going to be next weekend,

00:37the 6th and 7th, may get underway on Friday night, the 5th.

00:41And then there may be an opportunity for some rain to return to southern California.

00:44But those are the big-ticket items that we're looking at for the pattern for that period from December 5th through 10th.

00:49In fact, here is the big picture, if you will.

00:51You'll notice the big dip in the jet stream here over the eastern half of the country.

00:55To the south and west of it, generally warm and dry for the southern Rockies

00:58and for much of south and west Texas.

01:00But cold is going to dominate from the Dakotas to Minnesota all the way to Maine and to Boston.

01:06And you're going to see a series of systems coming through this flow.

01:09And as they do, they're going to tap into this cold air, and there's going to be an opportunity for snow.

01:13In fact, we're going to put a lot of snow on the ground here, I think, over the next couple of weeks.

01:16All right, it's like we're dealing with a big refrigeration process here as we establish more and more snow cover,

01:23which can influence the way it feels, kind of sometimes independent of the upper-level atmosphere configuration for short periods of time.

01:30Seriously, I mean, if you get an area of high pressure to come down over the snowpack on any given night with clear skies and light winds

01:36with these cold air masses, you could have some really, really cold nights that are hard to moderate during the daylight hours.

01:41So keep that in mind for this period.

01:43Now, as we go toward next weekend, one of these disturbances coming through the flow may try to work with really a northern branch feature

01:50and develop an area of low pressure coming through the Carolinas and working its way up the eastern seaboard.

01:55With all the cold air in place here, snow, I think, is on the table again for Chicago, Indianapolis, Detroit, Buffalo,

02:02even into parts of the interior northeast.

02:04Probably rain for the I-95 corridor, but even there it's questionable.

02:08So something we're going to be keeping an eye on, again, for that period, December 6th and 7th.

02:12On the other side of the coast, on the west coast, you're going to be looking at an upper-level trough of low pressure,

02:17trying to back away from the main jet stream flow.

02:20The question is going to be, does it bring moisture into southern California and an opportunity for rain,

02:24or is it really much to do about nothing?

02:26I think it will trend a little bit cooler as that works its way through and then it warms up once again.

02:30And that may be the last opportunity for rain for southern California for the foreseeable future.

02:34All right, so a lot of our viewers here in the Midwest, the Northeast, we've got three separate storms in view.

02:40We've got the weekend storm, we've got the Tuesday Northeast storm, and then another one that you're tracking for next week.

02:46Joe, lots going on.

02:47And there's probably two more after that, I think.

02:49All right, well, all aboard.

02:51We are dealing with some pretty good cold and snow here into the transition to December.

02:56The crystal ball, Joe Lumberg, we always appreciate you, Joe.

02:58You're quite welcome.
