If there’s one thing the EPS/GEFS agree on, it’s a active southern stream delivering precipitation to the SE, undercutting signals a active southern stream, sort of like a nino

Ga - was wondering if you could ask Maxar if the CMC Ens cold bias is more tied to the western U.S.? I see this a lot where it will just keep the Rockies and Great Basin cold no matter the pattern (would be nice to have that in real life huh)
Wonder if that has anything to do with the freezer they was just in with the exceptionally strong -PNA the last 2 weeks of decGa - was wondering if you could ask Maxar if the CMC Ens cold bias is more tied to the western U.S.?

Might be some light ZR for CAD areas sun morning 
Some noise showing up around the 17th on the EPS 
Yes… I feel like the 16th-18th is when we should zero in on that time frame, but there’s enough energy and cold air around to have multiple threat just after that. With the MJO progression, +PNA, and the AO looking to go negative I really think we could all have some late nights of model watching coming up. Though I still doubt we see a fully west based -NAO, any bit of blocking near Greenland can only help
18z should be interesting
Energy digging farther south this GFS run 
18z GFS going to show a big fantasy storm here in a bit. Buckle up.
Yeah, big developing GL vortex and 2 southern stream waves….

Woof..like that low height feature off the southeastern coast. Been seeing it a while now. Should keep a ridge from flaring up and spoiling our milk. There are many ways to fail, however.
Southern stream energy and pacific energy in MT entering at the same time with a vortex in S Canada 
Definitely like those lower heights over the Atlantic.
Pretty good west coast ridge extending up and into eastern AK
Lots of energy undercutting that +PNA
Wavebreak printer go brrr, which leads to a nice -NAO, love that SE Canada vortex 
---- the lakes low
