it's an interesting run there over next weekend too.  the flow is so fast everywhere that the lower troposphere doesn't have time to warm up on the backside of the high. The next wave/arctic boundary has a 'polar warm sector' with it. 

We saw an event like that in late February 2015 I recall...it was after the whole snow blitz in the first 2 weeks of that month...but we had this ugly system tracking west of us but given the entrenched arctic airmass that month, it didn't turn us to rain. We got something like 3-7" of WAA snow from a bit of a ragged radar presentation...with splotchy jackpots. The southwest nature of the WAA in the lower levels was probably not very conductive for good moisture transport. So it wasn't a great looking event. But it was just another advisory type snowfall on top of the 3-4 foot snowpack we already had:

That was Kevin's AWT trend to colder storm. We did mix with rain at the tail end, but I recall 3" or so.

What we need to kick is this fast multiple shortwaves everywhere type flow.  

It screams a lot of fast moving light to moderate events with terrible modeling leading up to them.  

 

We may get a bit more amplified as the ridge shifts eastward...turns into a more classic PNA ridge...that will help a little. But even then, it's still looking like a pretty fast flow.

That could be a commute disaster Friday morning. That would be RASN or RA to briefly start and then flash to snow with temps in the 20s. Yikes.

was thinking the same thing, but because the last one failed they all fail according to some. Guess they erase from their memory the truly impactful Arctic fronts
