Very well could, if we get northern stream energy further ahead of it/stronger around the GL, could be a nice storm, plenty of time to trend either directions, euro was solid but it weakened the energy near the GL, but the CMC looked really good with that
That’s almost exactly how we need that N/S trough to look with the second system, or like the Canadian

Remember what I said , can’t play with fire and not get burned . Need to smell the 70 and sunshine before you can get the 32 and snow . It can be 70 and sunny and never get cold and snowy but it can never be cold without there being warm . Well 1977 but that was dry as hell and frigid , then the month after was really warm and hit 81. So I guess my rule still works .
Yeah the gfs was about as bad as you can get if you want snow. Need something more similar to the euro/Canadian to have a shot. I mean it essentially is a split flow across NOAM at that point so we are probably going to see a few wild variations over the next few days. Wouldn't be at all surprised to get a wound up cutter and an overrunning event on the models as they try to resolve the wave interactions

Looks good for Brent.
I'm just going to leave this here:
I like the GFS somewhat keeping stuff close Around the 50/50 region Relatively consistently 
It’s nuts seeing the 500mb pattern like that yet have most of the US above normal at the surface. Why couldn’t they have left the GFS alone. Every time it gets a upgrade it gets worse and it wasn’t great to begin with.
Now you’re speaking my language!

Random -- do you know if MJO phase is uniformly distributed (e.g. is Phase 1 equally likely to Phase 6?)?
Glacier National Park is the benchmark for northern stream parcels with phasing potential, I’d like to see the leading wave over the west central Plains but it’s workable given the t-step. Heights though along the EC/MA are above spec.
I know that as of recent, the MJO is much slower, and I'm far from an expert on tropical forcing, but these is the probabilities:

On the morning of Sunday, January 9th, a low pressure system formed in the Gulf of Mexico just off the Texas coast. This low pressure system traveled parallel to the Gulf Coast throughout the day on Sunday and into the day on Monday before moving over the Florida Panhandle and off the Atlantic Seaboard Monday night. Even though the system weakened as it moved eastward, it brought moisture across Central Alabama, where cold temperatures were already in place from a cold front that had moved through Friday and Saturday, the 7th and 8th of January.

By noon on Sunday, weak reflectivities were already on the radar, though, it wasn't until about 2 PM that afternoon when Tuscaloosa began reporting unknown precipitation. The bulk of the activity started later that evening, but because of an elevated warm layer of air that moved inland as the low pressure system passed to the south of Alabama, the southern half of the county warning area didn't receive any snow -- just ice and sleet. By daybreak Monday morning, areas north of Interstate 20 were reporting anywhere from 1 to 14 inches of snow with the heaviest totals near the Alabama-Tennessee state line. Ice reports were as high as 0.50 inches in multiple counties south of Interstate 20.
- Local Storm Reports from the event.
The ice and snow from Sunday night and Monday morning created havoc across most of the state. By Sunday evening, businesses and schools had already declared they would be closed on Monday and for good reason. Road conditions around central Alabama caused many counties to declare that roads would be closed overnight Sunday night. Unfortunately, this winter weather event caused the loss of at least 2 lives on area roadways because of slick conditions.
Though the majority of the activity was over by Monday night, the effects of the system were felt for the next couple of days. Areas that saw excessive amounts of snow were plagued with melting and refreezing on area roadways for the next couple of days, creating slick conditions through Wednesday, January 12th.

Thanks! And sorry for the follow-on question here.. for the table from @Webberweather53, do you know if magnitude of the MJO is incorporated somehow? Looking at the forecast, I'm not sure how much the MJO is driving our pattern:

The Jan 11 snow is the only time ive ever seen patches of snow still on the ground a week later.
