We still waiting for the GEFS?

Slight shift north like the OP. Increased QPF in DC. Just looking at means. 

 

EDIT: Also actually a degree or two colder on the whole

GEFS has plenty of spread in terms of where the boundary lines up on this (and how it's timed with the heavy precip onset). The mean 850 freezing line passes DCA before sun-up saturday. this is 12z saturday.

You can keep your money. Obviously light snow isn't going to accumulate in the afternoon. But heavy snow will. Also why should it matter whether it's PA or a little further south? The sun's radiation isn't a whole lot different there vs here.

This is a dumb argument. Yes the radiation will make it harder. But it doesn't mean it can't stick. If it's light or 35 degrees it won't. But if it's thumping at 32 it will. 

Look at places with elevation at our latitude. They get snow this late all the time. They get the same radiation. Their elevation makes it easier to get cold enough air this late though despite the increased radiation. But when it snows the radiation doesn't stop accumulation. Especially because if it's snowing hard the radiation is muted by the thick cloud cover and precip. 

So yes it will make it harder. But the biggest issue getting snow in April is getting cold enough. Places with elevation at our latitude prove it can stick if it snows hard.

Wompwomp.  Euro north as well.  850 temps above 0C at 12z Saturday along a line about 10-20mi west of 95.  

Yeah, low is further west, so it may just be delayed and not denied.

Haven't seen it yet, but you're probably right.  But still means all snowfall would be during daytime.
