December 2025 OBS and Discussion

I'd like to see a sharper trof like last night's GFS and UK. That allows more intense and widespread precipitation and it also anchors the surface high further west in Quebec due to the strongest upper level convergence staying further west. With a more positively tilted trof, the surface convergence shifts east and the surface high goes with it.

(upper levels and surface are connected in the sense that converging air aloft tends to sink [surface high pressure] and diverging air aloft tends to rise [surface low pressure])

I thought the Euro is usually overamped and the gfs is too progressive.

Obviously not after 12Z run

We are back to bashing all models that don’t show our preferred solutions and praising the models that do, no matter what model it is. 
 

gotta love this place.

Yeah, and it doesn’t matter if they are a warminista or weenie - everyone cherry picks what model supports their position.  And everyone is right!  At least for a time…

nobody knows what's going to happen yet, we know with our luck we usually get a whiff or a cold rain so chances are against us. Let's just sit back and enjoy the tracking that's half the fun! well maybe 25% of the fun.

Hopefully we get a frozen event or two in December-always love holiday snow/ice.

Gfs continues to be the most amped model. Inland does really well. Rain for the coast.

in albany for the next month and a half. 18z GFS is a dream

really different solutions between the GFS and most other models - IMO GFS is too amped and will trend further south and east similar to the benchmark solution it had previously.... and other models will trend west closer to that solution....18Z is a leftover 12Z solution anyways - newer data at 0Z

i just have this feeling where this is going to whiff

More of a chance of rain than a whiff IMO
