All 3 major models handling the 20th wave and the one behind it completely different. Todays Canadian buried that follow up energy, and todays euro brings it east and keeps the ridge strong. Differences between euro and the other 2 couldn’t be farther apart in the LR. We all know which ever one ends up being the worst for us will win .
GFS OP advertising a PV split around 300 hours. Not sure if we’ll get a SSWE, but maybe our only hope this winter? Wouldn’t feel the effects until late feb/March I think anyway. I’ll let smarter people who understand that topic better talk about it. .
It seems the energy that goes over the ridge around the 20th is being handled differently by each model and causing some issues. 00z euro tonight isn’t burying that energy like the 00z GFS. Compare euro and gfs @ 192 hours, not even close, .
00z GEFS and GEPS still different at day 9-11… GEPS is straight porn in the LR Think GEFS is different than euro/cmc because of how it’s OP and members handling those short waves day 8-10 vs other models .
18z GEFS back to looking decent. Improvement off the 12z run. With how ridiculous the OP run is there’s probably some members also doing crazy stuff with shortwaves going over the ridge .
Fine I’ll do it. Don’t hate me please. Anyone find it at least a little concerning that H5 looks great on EPS, but there’s little if any members showing snow in the next 15 days? .
Right the ensembles start picking up on individual shortwaves better as we get closer. Luckily cmc and euro look more similar to each other at end of run vs gfs.
00z gfs forms a rex block in the long range underneath the ridge, but you can see it’s about to dump the motherload of cold down south. See once you get a true -epo ridge only a matter of time for cold to work in .
This would be the beginning of the pattern change, so I don’t know if cold air has worked in yet, but damn this is usually almost a perfect setup. Main vort a little too strong, but have confluence and 50/50. Hopefully sign of things to come .
If the -EPO PNA does form as advertised it may take a couple NS disturbances to usher in the cold. Then we wait and see if we can time a shortwave because there doesn’t seem to be any Atlantic blocking to facilitate anything .
18z euro step back for our miracle secondary event. Knew that would happen this winter. What can go wrong will go wrong. Must of had sampling issues with that lead shortwave this morning. Still a few members have it, but mainly W NW of city anyway .
We should have a window from around Jan 22-Feb12 to get some snow if the ensembles are right. We fail during this potential -EPO regime that could take hold then god help us all .
Imo EURO H5 would argue for faster CCB development. You guys could be in a good spot for this if it happens, especially W Burbs which the ensembles favor. The secondary is looking like a real deal, figuring out where it forms going to take a while .
