Hawkeye Posted December 26, 2020 Report Share Posted December 26, 2020 The Euro continues to be very robust with a northern stream bowling ball diving south into the trough. There are definitely changes from run to run at 500 mb (this run the southern energy is slower and the northern wave digs farther sw), but the overall result is the same.

Tom Posted December 26, 2020 Report Share Posted December 26, 2020 2 hours ago, Stormhunter87 said: My guidance would be the gfs because of no northern snow pack to make sure the cold air in place. But so far this season the gfs has been the sniffer and euro pans out well. Is this in range of landfall yet? I won't count it out unless the NAM has a better idea. NAM is and will be off on the event but it's great on picking up thermals. The energy wont' be near landfall till about Monday morning when it comes onshore over Cali. Right now, its in a very sparse region where data is being collected. Probably whey we are seeing varying model runs per each global model. Pick and choose which one you like at this point. I'm expecting some even bigger shift or "ideas" from the models through the weekend. 4 Quote Link to comment Share on other sites More sharing options...
Tom Posted December 26, 2020 Report Share Posted December 26, 2020 00z Euro...expanded view...as @Hawkeyeand others have mentioned on here, some of the models are dialing in on a secondary low which has been an exhibit of how systems have formed this season. There have been a handful of those that focused on the secondary piece or wave while others did not. Although, it appears this particular storm should favor a development of the secondary low that rides up the frontal boundary up into the GL's region. With that being said, Euro showing some love for the Lower Lakes region... 00z EPS... 3 Quote Link to comment Share on other sites More sharing options...

clintbeed1993 Posted December 26, 2020 Report Share Posted December 26, 2020 NWS Hastings had a much better discussion this morning. Acknowledging the huge potential with this system. Reading their hint hint at heavy snow potential makes me think they're discounting the GFS right now. I agree with that. We'll be seeing shifts as this thing is sampled this weekend. EURO has been the most consistent and I'd go with it until it shows different. Quote Link to comment Share on other sites More sharing options...
clintbeed1993 Posted December 26, 2020 Report Share Posted December 26, 2020 "As mentioned yesterday, this system seems to have a plenty of moisture to work with, both at the low levels and mid/high levels with a potential stream of Pacific moisture tagging along. Ensembles suggest anywhere from 2 to 4 times the normal amount of moisture will be available. This is a 99th percentile moisture source...with the EC being the highest...and appears to a be a potential key to this event overall. With such moisture, snow accumulations may be significant. WPC has highlighted the northern half of the forecast area in the 30-80% likelihood of reaching winter storm criteria during the day Tuesday (that is 6"+ of snow potentially). There is no doubt the potential for a significant snow is on the table but "who gets what" is not really determinable right now. It is probably reasonable to say Nebraska has a better chance for more snow than Kansas. Areas northeast of a line from Lexington to Hastings to Geneva seem to be most favored at this point. Confidence and impacts: I wouldn`t write all this without some confidence this system will impact the NWS Hastings forecast. It seems increasingly likely a good portion of the area will receive as much or all of the normal December precipitation with this one system, if not quite a bit more in some areas. Significant amounts of snow seem likely too but its hard to pin a number on that 72+ hours out. Impacts have the potential to be significant Tuesday and Wednesday, and maybe even Thursday as winds continue to filter out of the northwest behind the low." 2 Quote Link to comment Share on other sites More sharing options...

Minny_Weather Posted December 26, 2020 Report Share Posted December 26, 2020 Models are way too juiced right now, I think that will be fixed when the storm comes ashore. That also likely means a climo-driven shift North. Or maybe I'm just wishcasting. Quote Formerly *ahem*: LNK_Weather, TOL_Weather, FAR_Weather, MSP_Weather, IMoveALot_Weather.

bud2380 Posted December 26, 2020 Author Report Share Posted December 26, 2020 I wish the NWS would be this blunt more often. And actually use their meteorological acumen to make these types of determinations instead of just regurgitating the models more often. This guy probably has forgotten more weather knowledge than I know, so I’ll go ahead and agree and ignore the GFS 3 Quote Link to comment Share on other sites More sharing options...

bud2380 Posted December 26, 2020 Author Report Share Posted December 26, 2020 I know it’s a lot to ask, but if the euro would just drop 100 miles south, that would be fantastic. 6z CMC also stays on track from previous runs.

We have the Canadian and Uk on our side. I’m sure that will change soon enough. I have a heavy lean towards the Euro at this point. We can only hope the Euro wobbles far enough south to hit us with the heavy snow band.
