Watching a GFS run is like watching Tennessee play football this year.  Sometimes I am like, "This is really awesome."  And sometimes I am like, "How is this even possible?"

Very timely observation.

Haha.  Very!!!

Losing snow events to wild modeling misses, and coaching searches are what we do best on Rocky Top. With how Heupel closed this season, and how tough the schedule gets the next two season, the coaching search will be coming before too long.

I feel your frustrations.  Being a BAMA fan, the first qtr against OK I was livid. 
All I hear is Indiana will kill us.  I was hoping UT would beat IL.  My gosh the banter of people saying the SEC is overrated just got louder.  Sadly college football is imploding.  I feel for schools like Iowa State & OK state.  They literally have 16/17 players left on their teams.  The portal & $$$ are killing it quickly.  Who would really want to coach college these days.  It’s a 365 days job.  Pros is much more easier.

The 00z AI GFS is even colder than 18z. Looks like it has a powerful frontal passage that plows through the moisture for some anafrontal snow, then a clipper reinforces the cold and brings a 1-3 inch type snow across the area. Single digit temps in its wake.

How's it handling the Thorn in the NEPAC ? Is it showing a weaker Trough there ?

Gone. Huge block into the Arctic. -EPO, +PNA, cross polar flow from Siberia.

The 0z GFS loses the feedback over Baja and looks a lot like the 18z AIGFS.  Let’s see how the rest of 0z goes, but they are trending colder as John has already noted with the AIGFS.  

[Carvers Gap]

I am also noticing at tendency on the 0z GFS to include split flow with the -EPO.

[Carvers Gap]

Sitting in Knoxville…

The 0z AIGFS is definitely quick with the EPO ridge as it installs it around the 8th, and the trough begins to kick eastward at that time.  Very cold model and the 0z GFS has basically joined it.  John covers all of that nicely above.

[Carvers Gap]

Nice looks and decent agreement in general with cold placement and vastness of the airmass.

Gawx like so many in here have been all over the data of temps trending colder.

Nothing burger from the 0z Euro.  I have read some conversations that the MJO rolls into phase 6 right as the EPO forms.  We may be seeing some of that.   The Euro at 500 is still better than 12z though IMO.  See u at 12z tomorrow.

[John1122]

The Euro has a LP that moves from Colorado, southwest towards So Cal and then it just sit there over the Southwest.

I just sits there with the firehose turned on over Arkansas and West Tennessee, up the Ohio River valley pumping in warm air and moisture. Like 3-4 days of heavy rain with zero movement eastward because there's a Bermuda high that would make summer Bermuda high's jealous. Even with a massive west coast ridge, and major blocking over Greenland/Davis Straits, nothing moves at all.
