Still trending IMO.

AO now forecast to dip to an impressive -4 around that time too.

I think the stronger block has merit.

Best case scenario is the trends continue and there's a double whammy of winter weather as 12th system acts like a 50/50 low for the next one.

Gist of the blog post I just made...'"Double Jeopardy" next week.

We'll see how the airmass is prior tot he storm....this run had a very chilly airmass advected down int he wake of 12/12 when that PV lobe retrgraded into Maine....it leaves us with a pretty cold airmass.

This is 12/14 at 12z. IF you start crushing the system off to the west a little sooner, then you are going to hold this airmass in a bit better upon approach.

Love to see the primary blow up west and spawn a secondary to cut off southerly flow.
