It really is.  H5 maps are nice, just 500 miles too far west. :facepalm:.  Maybe this storm sets something up after

The TNH pattern has been killing us. We’ve wasted several NAO blocks over the last 5 years the exact same way. The TNH ridge being pumped by “ya know” links to with the NAO ridge and pushes out any 50/50 way too fast so that systems can still cut. It’s been a repetitive issue.

Seems to be a decadal oscillation. It’s been pos for a while now

It is and it’s always been better for us when it’s negative. BUT there were more examples in the past of a -NAO being able to beat down the +TNH pattern and suppress systems under us.  Recently the TNH seems to be winning even when the AO/NAO are ridiculously negative.

My fear for after is this system pulls north and retrogrades, stalled from progressing by the link up of the WAR and NAO. So we’re left in the exact same conundrum.  Weak waves are likely squashed since were directly under the TPV but anything stronger that phases cuts since there is nothing to prevent it from pumping ridging to the North Pole in front. 

ETA: it could work, but would require luck with exact placement of features and phasing.  Been a long time since we got lucky. Some here subscribe to the were due index.

It's almost like we need a new non-traditional way to get snow around here.

New climo worries no doubt.  The warm pool  is killing us and has been for years. Add to that the lack of a 50/50 and ideal ridge placement out West and we fail. 

On paper the pattern looks great,  but when you look deeper the little things are preventing us from scoring.  The little cause cause huge implications.  

We just finished the first 15 days of December with a record - AO and ideal block North of Alaska, but we fail again.  I imagine in the future I will not to get too excited when the indicies look awesome because it means very little at out lattitude.  I admit I was wrong, I was very confident we would score at least a WSW critieria storm.  

Later this month faces the same issues of now. We might exit December with very little snow, such sadness.
