If it's moderate or greater, it will accumulate even in April. We have this argument all the time. If it's like 33F with 1SM vis during the height of the day, you won't get much.
It's a warm front lifting north, but the flow begins to turn and accelerate a bit Saturday morning and eventually pushes it southwest. So maybe semantics, but I wouldn't say it's just a warm front lifting north.
Just looking at the EPS, ridge retros a tad west into the Plains which could allow for warm front to stall nearby or just west, but still looks AN. Usually when that happens you get a pulse or two of good WAA.
Heights look to be AN for awhile. Obviously at the surface AN heights don’t mean a whole lot if we are wedged, but that’s a good sign of mild weather even if you get just a little sun and are inland.
