Yeah, AI was a good bit juicer with the qpf.

based on SLP track, one could argue that qpf depicted above is a bit underdone for skook n points NE.

MU take:

goalposts narrowed a bit, but subtle changes can make big differences for our W vs E sub members.  Still need to watch NS and how it dives in.  Need that to hold and not fold (some nooners less neg tilt, and some were a touch better).  Root for earlier interaction to keep trough neg so this thing can come up and not up/out. 

Based on progressive trough theme of this winter, its a worry of mine, but fortunately we are getting close enough that big surprises are starting to wane a bit.

12z Euro AI continues to slowly improve as well

12z Euro Op continues to improve. Not all the way to GFS land but everyone takes another step closer

I called him a whiny bitch on Twitter last night after he gave a snarky, shithead response to another hack, Mark Margavage. I have yet to see if MU responded.

euro AI joins the sharper trough team and looks better. 

 

Another +1 for team snowhounds
