Which algorithm though? There’s actual euro output which I believe is all your temp levels, qpf, and it may even have ptype...but the actual accumulation maps are usually produced by 3rd party vendors which interpret that raw euro data differently. In this case, if you are using a map that has an algorithm which severely punishes sfc temps above freezing then you’ll end up with an unrealistically low snowfall map. 

Even the pivotal wx clown map has like 18-24” over parts of E Ma. It’s just another way to interpret the data.

Normally the F5 maps are most accurate, but I agree that it looks to warm in this instance.

Yeah that is he Eurowx map (now called F5?) It’s another 3rd party vendor and they are usually pretty conservative and often correct...esp with sleet potential. But the marginal sfc here in this instance may hurt the accuracy because heavy snow at 33 is accumulating rapidly. Light to moderate snow may not. 

At any rate. This is all probably moot since we’re discussing a 6+ day solution. Lol. But it’s a good example of hashing out different clown maps and their limitations.

If it happens ,Isn’t this a Friday night event? 6+ days?

Agreed. I only looked at H5, then that clown map....not H925 temps, etc....not at day 6...so you can understand why I commented about the surface lacking. I agree, it would verify much snowier.
