Always the issue, holding out hope that this fropa is so strong that it'll be as if there is no terrain impediment with the plateau. Can't recall an analog likely due to how infrequently an arctic front of this caliber comes through. Wish I had an analog to point to in regard to plateau not slowing the cold, hoping and even expecting it'll bulldoze its way through faster than pretty much all events in recent memory.I think a lot of models are slowing the cold up as it hits the western Plateau, just enough for the moisture to race away from the front.

January 2014 had crazy cold too, I had to travel to Michigan to a hospital for a family member and that was the winter when every media outlet began saying "Polar Votex" in relation to the cold in an almost doomsday type term really talking it up. The day I left Michigan for the drive back to Tennessee it was -15 air temp in Detroit with howling winds and blowing snow windchill in the 30 to 40 below zero range. Got home in Tennessee that night and it was -1 air temp in Knoxville.

Yeah it actually looks better than previous runs to me. Moisture looks deeper and more of a SW fetch over the local region than previous runs. Odd looking even with that shape of the precip shield over Tennessee but a good look.GFS looks faster with the cold another 25mi faster east move like it was doing yesterday.

Oh the DGEX model!!! I had forgotten that all together until you said Earl Barker. That thing put out insane clowns. I miss those, they used to get folks so worked up!!Long range NAM clowns, particularly of the Earl Barker variety (if I'm remembering his name correctly) were high quality entertainment in years past.

I'm riding the GFS until this time tomorrow. Then I'll start hugging the meso models in particular the RGEM, but I'm a bit unnerved at the RGEM really want to see it come around because it used to score well inside 48 hours in particular.RGEM wasn't good at all. Just bone dry except for a small bullseye around the central plateau. Barely gets .2 total qpf for most areas.

Pretty much 3/4 of Minnesota is exactly how you picture it. The hilly area is mostly far northern Minnesota especially nearest to Lake Superior in the Arrowhead/Iron region.
I had no idea. I assumed it would be like Iowa, Nebraska etc…. Makes me wonder now if there’s hills in states I thought where basically flat. That’s a beautiful picture though

Montana, there are so many 'M' states and their abbreviations are so similar. Though Minnesota does have valleys, albeit low relief valleys.
Minnesota has valleys?

Clipper looks super stout behind the storm also on the 0z GFS.

Best run of the GFS in the last 24 hours!Actually not a bad GFS run. Snow totals were up. It looks like the cold is coming faster if you look at the trends.

Anyone notice the clipper on the 18z GFS after the storm. Would be nice to get snow while we've been below freezing for a few days. With the deep cold behind this system a clipper can drop a nice high ratio snow.

Agree, guess they view GFS as a bit of an outsider or 18z trended less.MRX is starting to downplay the backside snow. Not that they ever played it up or anything but they are saying the mods are trending away from snow. I haven’t been able to looked deep into the mods but reading this board gave me the impression that we held steady or maybe got a little better today.

Something else to note until this powerhouse storm gets through models will have a hard time seeing any clippers or energy diving out of the plains behind the storm. Think we still have potential for something after the storm, but before troughing eases back.

Agree, this will probably be the worst rapid freeze up we've had in many, many years. The wet surfaces will rapidly become encased in ice then covered in whatever amount of snow we get. This could be one of the worst events for roadways in quite a long time and of course occurring on a high travel period. I fully expect winter weather products to be issued by all the regions NWS offices for the freeze up during high travel days even if we get only an inch or less snow.
One thing that will also help (or hurt) is we are dealing with mid 40’s for several days before the snow starts instead of mid 60’s which is more typical. My point is there will be a wet ground with temps falling into the mid teens with snow showers. A 1/2 to 1” of snow will make the roads a disaster.

Usually in anafrontal snow chasing rain situations if you are in the Great Valley of East Tennessee you painfully watch and wait for the cold to spill over the plateau it creates a daming that slows the cold and allows moisture to exit before the cold spills over meaning we often get ripped off. However I think this may be the strongest arctic front I can remember in at least a decade, and with the pressure gradient I don't think the plateau will hold the cold back and create the delay we often see. This likely has high potential to bust higher in the Great Valley than normal anafrontal events of the past, keeping in mind though that most anafrontal events for the valley of east Tennessee are dusting to an inch type of events for most, so to bust higher doesnt mean crazy amounts but still potentially higher than most anafrontal events. Kind of excited to see this transpire, definitely not our everyday arctic front scenario.

Agree! There is a storm in history that resulted in one of largest maritime disasters in US history and the largest ever on the great lakes that resulted in 250 sailors deaths in 24 hours. It was named "The White Hurricane" and occurred in 1913, good read BTW if reading on it. While weather forecasting is better than back in 1913 so wouldn't expect the maritime industry to be wrecked like that, but this storm could be a "White Hurricane" with those pressures modeled!! Crazy low pressure would likely be 30 foot waves on Lake Michigan and Huron also possible Superior, even here those NW winds will be howling as currently modeled. Wouldn't be surprised if as modeled, that most of the forum area would go under High Wind Warnings, mountains for sure but possibly even lower elevations.Will be some nail biting for Michigan, Indiana. But they are in play for a whopper of a storm.

Yeah my fear as well. The whole suppression city situation where storms are pushed to Cuba. However even in those scenarios the transitions at the beginning and end of the cold snap give chances historically.My concern is the cold overwhelming everything and it's cold but dry. I think we then wait until mid-end January for our next opportunity. I know it sounds crazy, but just my two cents

Sitting at almost 4" think I can get to 6 or higher by end of event. Been a really good event.

Just saw lightning and nice long rumble. This storm has been pretty awesome so far! Little over 2"

Small flakes imby, but man it's pouring it. Visibility is crazy low and the wind blows it around in curtains. Doesn't feel or look like a typical southern snow, feels very midwestern blowing snow type snow.

Noticed when looking across my property towards light on my garage the trees look shiny almost like during the mixing and change over earlier, there may have been a brief bout of freezing rain as well. The trees are glistening. Currently sitting about .5" snow and 30 degrees.

I started getting some sleet pellets mixing in around 37 degrees here.Wondering if the changeover won't happen sooner, MRX had us progged for around 3AM however my buddy in Morristown has dropped to 39 now, at this rate wouldn't be surprised to see changeover 30 minutes before
