You will probably end up with a bunch tonight.   NWS is way off on this forecast. 

I do see now that they updated the forecast for 2-4 inches tonight, but the forecast from a few hours ago said less than an inch for the 24 hours starting late this afternoon.  2-4 tonight might be good, and it wouldn't count the snow that happened before about 6 or 7 o'clock. 

Guessing we have 6 new inches and still snowing.  They said all along that our area would be hard to forecast, and it depended on how warm it got today.  It stayed below freezing all day, and that made the difference.

So I had checked other forecasts, and the UW MRF 4k ensembles forecast may end up being the winner.  The ensemble mean forecast about 10 inches last night, and the 12Z forecast about 7.   I have often found that one to be pretty accurate.

GFS almost reverting back to its solution from 24hrs ago after feigning a trend the other way.

Really nice improvement on this run. I could tell just from this run to run comparison (thanks for those by the way because they are great) that the cutoff low would be weaker and further west. That translated well to the downstream trough digging much more sharply over us.

Yeah no problem at all. Yep a much improved run. I hope the next 2-3 days continues to show that cut-off low holding squarely under the center of the base of the ridge. If that made sense.

Let’s hope the Euro does the same.

The GFS’s current 500mb progression makes more sense to my eyeballs vs the warmer solution..not really scientific but whatevs.

Day 10 Long range looks messy/ugly maybe

That’s an uh oh. Probably just clown range shenanigans, though.

This upcoming AR hopefully is not a chilly one. I like the odd 55 and moderate rain type AR's every now and then.

Time for another upgrade.

Nice to see the improvement, though. Let's see if Daddy Euro follows suit.

Dr. No is stubborn. Could save face by caving now instead of holding out.
