Tom Posted January 7, 2015 Report Share Posted January 7, 2015 For a couple days now, models have been showing a Clipper to traverse the Great Lakes but recent trends now have accumulating snowfall a bit farther south and may affect alot more of the members on this forum in this region. Let's discuss this here... Snow ratios look very good so you can use the qpf being spit out and fluff those totals up... Quote Link to comment Share on other sites More sharing options...

gosaints Posted January 7, 2015 Report Share Posted January 7, 2015 Yes they definitely do. Will make for some nice wind chills and blowing snow.Looking like we might get fringed here. But if we do get a couple inches gusts are forecasted to hit 40 around here. Would probably be looking at on advisory for blowing snow Quote Link to comment Share on other sites More sharing options...

gosaints Posted January 7, 2015 Report Share Posted January 7, 2015 Pretty big difference between the two. What doo GFS/NAM show?In between. Hopefully the euro is on crack. The ggem should do better with a system originating in Canada. Higher resolution. There right? Quote Link to comment Share on other sites More sharing options...
Tony Posted January 7, 2015 Report Share Posted January 7, 2015 12z Euro...I don't trust the Euro with clippers. Last year it had a hard time with them and this past clipper it was weak with the qpf as well. Edit: It also has been last to the party with the past couple storms so not sure what's going on with that model. 1 Quote Link to comment Share on other sites More sharing options...
gosaints Posted January 7, 2015 Report Share Posted January 7, 2015 Gfs ensembles pretty much lock in step with the op. Think we could squeeze 1.5 inches here Quote Link to comment Share on other sites More sharing options...
Geos Posted January 7, 2015 Report Share Posted January 7, 2015 In between. Hopefully the euro is on crack. The ggem should do better with a system originating in Canada. Higher resolution. There right? Yeah a system in Canada should be handled better by the CMC model.It is showing like 0.30" of moisture here, which I think is a bit high. 0.2" I can get behind though. So far a forecasted 1- <3" here.

Edit: It also has been last to the party with the past couple storms so not sure what's going on with that model.GGEM/NAM were very good last year with Clippers, Euro not so much...tonight High Rez models should get a good handle on this system. I remember last year there were a couple similar systems like this one and it laid down a broad area of 1-3". Either way you look at it, this system is a "gift" if you ask me. Keep building the glacier around this region and the cold has more fire power to stick around for a while. Quote Link to comment Share on other sites More sharing options...

6789 Posted January 7, 2015 Report Share Posted January 7, 2015 FOR TOMORROW...CONCERNS WILL BE INCREASING SWLY WINDS AND A CHANCEOF SNOW BY LATE AFTERNOON FROM A MID LEVEL IMPULSE DROPPING OUT OFTHE NRN PLAINS. AT THIS TIME...THE MODELS ARE IN POOR AGREEMENT ONTHE EXACT TIMING OF THE BEGINNING OF SNOW AT THE TERMINALS...BUTTHE GENERAL IDEA IS THAT SNOW SHOULD IMPACT ALL OF THE TERMINALSBEGINNING BY THE LATE MORNING HOURS AT RFD AND THE AFTERNOON HOURSIN THE CHICAGO AREA. SOME ACCUMULATING SNOW IS LIKELY WITH THISSYSTEM.LOT seems on board with some sort of accumulation, even has RFD in on it. Really wish LOT would have kept the WCW in place, but temps just didn't get cold enough. Anyone think they will actually see WC readings of -33 tonight? I still have a feeling that the low temps will bust and most areas will stay in the single digits below zero. Quote Link to comment Share on other sites More sharing options...
Tom Posted January 7, 2015 Author Report Share Posted January 7, 2015 18z NAM...general 1-3 for NE IL...2-4" for Wisco...better snows for Michigan...I think 1-3" for N IL is a good bet... Quote Link to comment Share on other sites More sharing options...

Tom Posted January 7, 2015 Author Report Share Posted January 7, 2015 18z RGEM looks exciting for our area.I think its way overdoing snow ratios, but the general idea of the snow shield has been consistent. BTW, the RGEM nailed the southern shift of the heavy snow band through DSM to Ottawa, IL for the last Clipper. Quote Link to comment Share on other sites More sharing options...

East Dubzz Posted January 7, 2015 Report Share Posted January 7, 2015 Interesting. The Euro has like absolutely nothing, the RGEM is kinda interesting however. I surprise little snowfall would be nice, but not getting my hopes up. Quote Link to comment Share on other sites More sharing options...
Geos Posted January 7, 2015 Report Share Posted January 7, 2015 Maybe better to look at the moisture map for the RGEM and apply a lower snowfall ratio. That map above would suggest 30:1+ ratios!

East Dubzz Posted January 7, 2015 Report Share Posted January 7, 2015 Wouldn't mind that tiny little .25" QPF hitting me. Lol, either the RGEM is onto something or its gonna fall on its face. Quote Link to comment Share on other sites More sharing options...

Trinomial Posted January 7, 2015 Report Share Posted January 7, 2015 The 1800 UTC 4km NAM is showing between .10 - .25 for parts of N IL. In this time frame, the model was spot on with the last clipper. Should be interesting to see the 00 runs. Quote Link to comment Share on other sites More sharing options...

I think this over performsSame here...last nights light snow that swept through KC/STL area was not supposed to be all that impressive but if you got underneath those heavy bursts it accumulated pretty quickly. This system will have a little better moisture supply and it will be falling along another arctic front. I find these situations bring surprises here and there.
