Trusting those silly NE forum dudes. The Southern wave was quite a bit flatter so it didn’t gain latitude even with higher heights along the east coast.
@yoda check out the 0z ICON. See the Vort over the lakes at 36? It’s not going to phase into the Saturday storm and as a result I’d expect the Sunday one to come north from 18z
I think the sleet line “racing north” is a little misguided. It’s merely following the light rates at the south of the precip shield. Keep the rates and everything looks on target to keep snow until 16-17z for dc and 18z for Baltimore
Will depend on the final low track no matter if you start as snow or not. I have a rooting interest down there as my sister lives just north of the city. GL!!
