It really won't work. Seriously.we need to get in to some serious deform to get a meaningful accumulation.

I had mid 40's and rain that switched to snow in the mid 30's and stick no problem a few days ago. Don't take this the wrong way but your posts really do suck.

Not real surprising to see this hit..

Look at all these 990s ns lows up in Kentucky and north Tenn. at 18z compared to previous runs

It’s going to be another 24 hours before the models resolve the moving parts.

Til then we will be all over the place. Over in the banter topic I wasnt on the ledge, I was just pizzed at my pos dad for making me leave that once in a lifetime snow squall at 445pm this afternoon.

CMC did not have the same amplitude of the western ridge and wasn't as clean with the NS/SS interaction. I haven't seen the surface panels but it's not perty looking like the GFS at 500.

 

Edit: But it is a big improvement compared to its prior runs and gets some light stuff into the region so it is definitely moving towards the GFS type solution. See the trend below from the last 4 runs.

Just took a look at the NASA GEOS-5 model (https://fluid.nccs.nasa.gov/weather/wxmaps/). The maps are terrible to read but the 12z run was super amped- precip shield to lake erie and ptype would be an issue all the way back to i81 based on 850s.

I know people love to use it for aerosol transport and reanalysis but not sure how it does in these situations. Just another data point to balance the ecmwf run I guess.

Thanks for the post and link.  Very interesting to see.
