The initial ridge spike dislodges the PV lobe which then gets trapped underneath the block. Whereas in 2014 there were constant reloads of the EPO ridging that brought down PV lobes. Either way, it gets to a fairly similar look in the CONUS, with a strong polar jet directed right into the subforum and a train of Pac hybrid shortwaves.

A rally for the ages if that happens. Even 98-99 took much longer to get to 50", which is right about where the final total ended up. 1 Link to comment Share on other sites More sharing options...

Only thing is it wouldn’t be clippers of Alberta/Saskatchewan/Manitoba origin...But instead of PAC NW origin, due to positioning of the PV lobe. . 3 hours ago, RCNYILWX said: Aside from the extreme NAO block, the pattern this weekend through next week is the closest looking to 2014 that we've had since 2014.

Sent from my SM-G965U using Tapatalk I'm assuming that would portend more moisture than with a typical clipper track and hence more flake stacking. If that's the case, count me in, even if I have freeze my reasoner to get the snow. Link to comment Share on other sites More sharing options...

Don't get any lake enhancement with southern stream storms but often do with the clippers especially if they are associated with a re-enforcing arctic surge. Totals usually aren't over 6", but it often comes down fast and with wind and low visibility. Spreads the wealth inland much better than typical lake-effect too. 2 Link to comment Share on other sites More sharing options...
cyclone77 Posted February 4, 2021 Share Posted February 4, 2021 Looks like a good chunk of the DVN cwa has a legit shot at achieving 20"+ snow cover by next week. Euro shows 10-15" of snow to fall on an existing 10-15" of snow cover. The multi-layers of ice mixed in with the snowpack, and additional heavy cover to come means we won't be seeing the grass for quite a long time it would seem. 3 1 Link to comment Share on other sites More sharing options...

The 00z Euro looked really good on Sunday and it had good support from its ensemble and the signal for Monday is still good with GFS/GEFS the most excited. Edit: I see the 06z Euro shifted south on Sunday, but that's not really a big deal in a pattern like this. Could easily come back north, as the guidance is going to struggle with exact positioning of the baroclinic zone and the influence of the PV being to the north. 2 Link to comment Share on other sites More sharing options...

ILSNOW Posted February 4, 2021 Share Posted February 4, 2021 The wave train seems to be temporarily derailed we need to trend back to the 12z and 18z runs from yesterday. There are certainly going to be many opportunities over the next 5 days or so. Lets reel em in. EDIT And 12z GEM comes in with something in for the monday/tuesday time frame with a nice hit for C IL,N IN and western MI. Gives northern IL about .3 to .4 precip with ratios north of 20:1. 1 Link to comment Share on other sites More sharing options...

Looks really nice for Sunday evening/night through Monday. I think ultimately the later Sunday-Monday period has a decent chance to work out for a solid event. Saturday PM should snow in most of the CWA but needs work to be anything more than a 1-3" type event. Sent from my SM-G965U using Tapatalk Link to comment Share on other sites More sharing options...

Malacka11 Posted February 4, 2021 Share Posted February 4, 2021 For every bit of hope we lost for this weekend/early week, there's more opportunity springing up around the 160 hour mark. Monday still looks like it could easily by a 5"+ event if things work out alright, I don't see why everyone's pissing and shitting themselves.

RCNYILWX Posted February 4, 2021 Share Posted February 4, 2021 model huggers never learn:facepalm:In this sort of a pattern, each operational run needs to be treated similarly to an ensemble member. A good way to tell a pattern is active and also prone to less lead time for higher predictability is looping 6-hour QPF or snow on the ens. Starting Saturday there's members that have action every 6-hour block, with certain time periods a bit more favored than others. With multiple lower amplitude short-waves it adds a lot of chaos to the modelling. Sent from my SM-G965U using Tapatalk 2 Link to comment Share on other sites More sharing options...

Guessing people will be getting tired of the cold by thenThere’s actually growing support for a pattern change.As of now ENS show the -AO/-NAO we’ve seen relax to neutral, the -PNA going neutral or + and the neutral EPO going +. That all combined with the MJO expected to be in phase 7.Could lead to a more volatile pattern with warm/cold swings, or a just warmer pattern overall.We’ll see if ENS continues to show this, or if it gets pushed back a bit...how all big pattern changes usually do.. 3 Link to comment Share on other sites More sharing options...

If the past is any guide, the 09-10 block actually lasted into March but by the cold air was gone. I'm not sure how much influence the MJO is having as most phase diagrams have it looping around in 7, with only CFS trying to send it into p8.Sent from my SM-G965U using Tapatalk Link to comment Share on other sites More sharing options...

All in all, not really disagreeing, will probably be last week to 10 days of the month before there's much change. By then, some huge negative departures will have been built up and snow pack should also too, which could also help serve to delay a noteworthy pattern change.

madwx Posted February 4, 2021 Share Posted February 4, 2021 another thing to note is that the Stratospheric Polar Winds had their last reversal a few days ago and are now forecast to return to normal levels by mid-month. The tropospheric flow has been disrupted and the cold air will be dislodged for a while but there won't be any more stratospheric disruptions until the final warming later in the spring. 3 Link to comment Share on other sites More sharing options...
