CoastalWx Posted December 7, 2010 Share Posted December 7, 2010 This was also another reason I wanted to see the clipper blow up with a secondary...becoming a little nuke in Canadian Maritimes...to steal any strength left in that rotting primary that hangs up over Ontario...which would let more high pressure build in via confluence forced by the intensifying 1st system. Yeah it leaves a rotting airmass, which is horrible for me...and even not good for your area. The trend has been to leave the 540 line just south of sne and 850 temps barely below 0C, prior to the storm's arrival. That's never good when you have a low bombing to the southwest. Maybe God's country can squeeze a few inches. Link to comment Share on other sites More sharing options...

Maybe God's country can squeeze a few inches. The previous solutions had a pretty cold airmass over the region with around -10C 850s. A stronger 1st system..esp if it blew up in the G of Maine and Nova Scotia...would definitely get a much better antecedent cold airmass in here prior to the 2nd system as well as probably helping force that one a bit south. But it doesn't look like we want to trend the best direction with that clipper the past 24 hours. Link to comment Share on other sites More sharing options...
skierinvermont Posted December 7, 2010 Share Posted December 7, 2010 I have an idea of how this might trend towards something colder, tell me what you think. One difference I noticed from the 12z/18z to the 00z is the 00z is slower, and this seems to give more time for the PV over Hudson's Bay to advance SE. This seems to create some more confluence over the NE and knock down heights over eastern Canada. So perhaps if the storm were to trend a little slower and the PV a little farther SE, we can push this just offshore. Not saying it's likely, but if this were to trend east this seems to me the most likely way for that to happen. The clipper seems to be becoming fairly irrelevant at this point. The storm is so amplified that it is just kicking the clipper out and there's hardly anything left of it by the time it reaches Newfoundland to create any sort of confluence over the NE. I have little to no hope that the clipper will trend strong enough to knock down heights behind it. Link to comment Share on other sites More sharing options...

That's all I want for now..flurries don't really count. Link to comment Share on other sites More sharing options...
ORH_wxman Posted December 7, 2010 Share Posted December 7, 2010 5H on the first clipper actually looks decent coming through the midwest...its deeper. But it just doesn't have much room to dig...both via ridging behind it and ahead of it. So the qpf is still pretty paltry across our region. By 108h, it looks like the PV is ready to get involved in the 2nd system, which will amplify it a lot. Link to comment Share on other sites More sharing options...

CoastalWx Posted December 7, 2010 Share Posted December 7, 2010 D-1" on the euro?? There might be a little more qpf with se boundary layer flow and such a cold airmass, over eastern areas. Link to comment Share on other sites More sharing options...
ORH_wxman Posted December 7, 2010 Share Posted December 7, 2010 8 7h look saturated, any QPF? QPF is mostly under a tenth...so I wouldn't expect much more than an inch of snow verbatim on this solution. Link to comment Share on other sites More sharing options...

It looks like it has potantial at H5, but it can't get the lower tropospheric response from that. I wish it were a few hours slower. Link to comment Share on other sites More sharing options...

Yeah, you'd think looking at H5, it would have a bit better reflection at the sfc further southeast of the primary. We maybe we will see it come around in terms of better qpf/slp reflection in the coming runs. I really wish that PV in central Canada would stay disconnected form the 2nd system too, but its looking less likely that for that to happen.
