Ostrich December

Yeah I'm just not seeing the storm signal for next week at this point. No solid cold signal that we usually need for a winter storm east of the mountains in the carolinas. Ensembles are varied from cool to warm. Likely the not yet backed up AK vortex of doom's doing. That's probably not going to cut it, especially in December IMO. But who knows, maybe it will head west and we get colder.

I'm more excited about keeping a sustained -AO and -NAO to play with and hoping to see that continue long term into January. That's a huge deal that we haven't had in a decade if we can actually make it real. We're likely to get a PNA here and there for occasional delivery, and when we do we'd be set up very nicely I think.
 
Even the Euro is locked in with that snow in OKC. I’m looking forward to returning there next month. Maybe I will cash in!View attachment 56571
I visited OKC last year. Loved it out there. Spread out and didn’t seem overly crowded. The bombing memorial was a site to behold.
 
The AK vortex is backing SW towards the Aleutians over successive runs on the long range GEFS, pumping the heights in the west >>> +PNA. Unlike our recent +PNA, this one has the potential to inject some seriously cold air into the east-central US given the Siberian air mass that will be parked over the NW territories and Alaska next week. We just need a few strong Rossby Waves in the right place at the right time to send pieces of it hurtling in our direction

Euro is dampening the ridge in the west more and more. Less digging of the shortwave, more positive tilt and shearing. Crappy dynamics and marginal cold mean another rain with the potential to end as a few flurries. Will be interesting to see if this trend stops or reverses at 0z
 
Like the GEFS, notice the tropospheric polar vortex over north-central Canada is sinking further south w/ every ECMWF run of late.

Its interesting. We sort of sacrifice the Monday system due to the TPV sinking south and shortening the amplitude of the ridge through the rockies for a better potential in the D7+ range or am I totally off base
