Euro consistently had 0.50"+ of ice accretion not only days ahead of the event, but on the day itself! Then the December 15th event where the Euro painted a stripe of 7"+ for Northern Indiana about a day or two leading up to the event. We ended with about an inch. Just so you know snow maps don’t come The model. They come the vendor. Some of the algorithms are weird. Link to comment Share on other sites More sharing options...
WxMatt21 Posted January 22, 2021 Share Posted January 22, 2021 Just now, michsnowfreak said: I do remember the ice failing, I thought you were just talking about snow. As for December 2nd are you thinking of the storm that went to Eastern Ohio and hit the Eastern part of the sub? Or something different? That pounded Cleveland with almost 10" and was actually my biggest snow of the season so far with 4.3" on the Western edge. Of course model placement always sucks more than a few days out lol. Hopefully this one delivers. Oh, I was just commenting about northern Indiana, particularly NE where we don't get much lake action. Both ice and snow have been exaggerated in recent memory on the euro, but clearly that's not the case everywhere! 1 Link to comment Share on other sites More sharing options...

purduewx80 Posted January 22, 2021 Share Posted January 22, 2021 18Z Euro stronger w the northern stream again. Doesn’t go out far enough but would almost certainly end up farther south than the 12z run. Respect the west-based -NAO? 1 2 Link to comment Share on other sites More sharing options...
Hoosier Posted January 22, 2021 Share Posted January 22, 2021 My way too early guess for ice would be for a band of 0.25"+, perhaps up to 0.5"... probably between I-80 and I-70. Not that entire area but somewhere between there. CIPS has decent support for several hours of freezing rain, and it's GFS based and may be underplaying. Plus looking at this setup conceptually, I see little reason why there wouldn't be a band of decent icing. It's a pretty typical look. Link to comment Share on other sites More sharing options...
RCNYILWX Posted January 22, 2021 Share Posted January 22, 2021 I'm not seeing stronger with northern stream, if we're referring to the PV lobe over Manitoba. Unless I'm looking at it wrong it looks like it's a hair west northwest of 12z and there's subtle higher heights than 12z over eastern Ontario. To me biggest change is the shortwave is a little slower and more positively tilted. Could get to that farther south outcome anyway but I'm not sure it's due to the northern stream.

RCNYILWX Posted January 22, 2021 Share Posted January 22, 2021 Yeah I thought that 90 hour looked good. Without nao we’d be raining Been thinking the same thing, feel pretty confident that sans blocking this would be a much warmer outcome. The blocking could yield a failure mode, but the heights ahead of the wave are already pretty amped, with no block, they really pump and SLP track is probably over the LOT CWA.

Sent from my SM-G965U using Tapatalk Yeah the Southwestern shortwave is def slower too. I see a more expansive upper low over MB that is about 60 m deeper too. Best I can tell the confluence would be a hair farther south. I guess my point was based on the MB wave trending stronger and bigger the past few runs. If that trend continues, suppression would probably continue. 2 Link to comment Share on other sites More sharing options...

purduewx80 Posted January 22, 2021 Share Posted January 22, 2021 It’s also important to point out these short waves rounding the south side of the NAO block are in a data sparse region and will be until the weekend. These go on to make up the MB wave that affects where confluence is, etc. I would normally trust the Euro 4DVAR to catch everything but in this case I’m not sold. Probably the best bet as usual at this range is a blend of current guidance. 2 Link to comment Share on other sites More sharing options...

A lot of strong members but the mean is kept in check because there are such varying placements of the snow swath. Still a few duds but not many. 1 Link to comment Share on other sites More sharing options...

The PV lobe southwest of the block that's also a key player is up over NW Territories. Sent from my SM-G965U using Tapatalk 2 Link to comment Share on other sites More sharing options...
