00:00after a warm Christmas week for many what a different week we have this week cold is king

00:12this week from the lakes toward the northeast and there will be the potential for two storms

00:17actually three we have our arctic boundary Wednesday night Thursday I don't think that's

00:22a big deal next week Thursday Friday and then a week from now you have another threat mid

00:28Atlantic in northeast I want to show you the pattern that we're going to be dealing with here

00:33as we go in the mid-January here and what you see is it's just been incredible cold across here the

00:41northwest territories and the Yukon territory now it's not as cold as it was but what's going to

00:47end up happening is you're going to see episodes of cold air coming south and east and then you're

00:52going to have a storm track coming in here as such or a storm track along the coast but with

00:59the cold air getting locked in of course that means you're going to have opportunities for some snow

01:04moving forward here now opportunities doesn't mean you're going to get it but I do want to show you

01:09about the three excuse me opportunities for snow from the lakes toward the northeast and then the

01:17mid-Atlantic to the northeast we begin and I talked about this last week the um the arctic boundary

01:24that's coming south as we move toward Wednesday into Thursday let me this is the upper air on Tuesday

01:30and here it is what you're going to see is this energy here going across northern Saskatchewan that's

01:35going to come southeast and as we get into Wednesday watch it come southeast now last week we talked

01:42about well if this trough could dig a little more and come like this then we can get more widespread

01:50snows across the uh midwest and northeast however however this doesn't look like this trough's going

02:00to dig far enough you see it watch it's just coming across it you see how it just comes right through

02:05the northeast the GFS that's the European GFS European same way this is Thursday night in the Friday

02:11morning and when you look at the surface map watch you're not going to see much snow here you see

02:16here it is it begins New Year's Eve in here across Minnesota watch it just come across the midwest

02:23there it is third Wednesday night and then in the parts of the northeast and Appalachians as we get

02:31into uh New Year's Day and because the trough's not deep enough this snow will not get east of the

02:37Appalachians so this is not going to be a threat for the I-95 corridor at all uh this is the area

02:43that you're going to see the snow and it's not going to be a lot as I mentioned uh it's generally

02:48going to be a coating uh to an inch or two here right in there now over the next this week the one

02:58area that's going to get slammed is in the lakes south of Watertown south of Buffalo there's going to be

03:04feet of snow but outside of the lakes we have a general coating to an inch or two and that's it

03:10from this storm this will be Wednesday night this will end up being Thursday and then Thursday Thursday

03:15night across New England not a big snow could be a disruptive snow and then there's a real shot

03:21of some very cold air then coming in behind the system now I want to take you forward then then I

03:28think for the most part it's going to be cold and dry as we get into early next week but I do think

03:33there's an opportunity along the mid-Atlantic and northeast Thursday and Friday and next week let

03:38me show you why as I show you the upper air map here uh so again we're going to go forward here

03:44again rounds of cold it's going to stay cold um across the northeast and the midwest but this is the

03:53setup there's Tuesday I want to show you this here's the setup as we get into Wednesday and Thursday

03:58first of all you have this upper low south of James south of Hudson Bay that continues to send

04:04colder air down watch as we get into Thursday we're going to zone in on this southern branch of

04:10the jet stream that's going to eject this piece out the northern branch sends in the cold the southern

04:16branch sends the storm now watch as we get into Thursday right here okay so Thursday Thursday night

04:24here's the cold air so this delivers the cold air this is the storm now it's not the right setup right

04:31now because what's happening is is this piece of energy which will end up being the surface storm

04:36will be driven out to sea not up the coast and you can see why as I get in the Friday morning see right

04:43in here this trough is a little too farther east too far east so this storm that forms is driven out

04:51to sea let me show you the surface map you can see it as we get into Thursday see here's the storm

04:56as we get into Thursday right in here but the upper level the way the trough is situated it keeps it

05:02separate from the cold air and moves it out to sea see right in here out to sea virtually no snow with it

05:10however let's keep an eye on this because let me go back to this I'm going to stop it right here

05:17this is Friday morning now if this piece of energy right here coming across Manitoba and into the

05:26in the Dakotas if this is a little farther west that pushes this trough instead of like this

05:32let's say the trough is a little a little more digging more like this then instead of this storm going out

05:40to sea it comes up the coast with plenty of snow let me show you the surface map so the surface map

05:46is taking this storm out to sea but if this trough is a little farther west then this storm would come

05:53up northward like this and then you could be looking at a snowstorm across parts of mid-atlantic and

06:00northeast now the modeling doesn't show that right now but we're going to keep an eye on that one last

06:06thing then as we get into the first full week the first full week of January I want to show you the

06:14upper air map here quickly right in here now this is interesting as we get into Monday and Tuesday

06:20your trough is back here you got a storm trying to come north now Europeans suggest it's too warm but

06:27watch you've got the possibility of a snow and ice event from the midwest into the northeast as we get

06:33to the 12th and 13th of January so that's early next week a week from now actually no two weeks from

06:40now the 12th and 13th so again we're going to keep an eye on things as we get into Thursday and Friday

06:47as we get in the next week and then let's keep an eye on the week after stay with us
