18z RPM also delivering the good stuff for elevated locations tomorrow

I wonder how many more runs it will take until the trough in the west is wiped out. My guess is probably another 2 cycles.

And here is the EPS shifting once again...nothing too surprising, but I am pleasantly surprised to see some positive height changes over Greenland.

EPS also starting to show some snow for the interior. 90% of this is from the second wave.

Just gonna drop the UKMET in here and see what happens

RGEM actually looks surprisingly robust for tomorrow

We continue to see pretty substantial corrections in the D7-15 timeframe on both the GEFS/EPS that make sense when recognizing the bias and upcoming pattern. I'd look for the Pacific (EPO region) to continue to adjust in subsequent runs and continue to look for increased heights over the western CONUS/Canada in addition to decreasing heights over the Aleutians. As @Isotherm has said, late December is really picking up some steam in terms of cold/storm potential. (ripping these images will result in an immediate permanent ban)

More professionals putting out some interesting data this morning

I've been wondering about the source as well. I always see it floating around on twitter. Looks like something the CPC would make.
