Sunday has a pretty interesting setup... definitely has some upside potential

one of the major features that we often need for a larger system to have a reasonable shot at delivering throughout the MA from VA to NYC is the presence of a 50/50 ULL to provide some confluence. we would definitely have that here. the TPV that's responsible for the +NAO is actually delivering significant confluence here, acting as a "fake" block

there's also a highly anomalous ridge that forms from the Rockies up into W Canada, which will allow for NS waves to dig and amplify as the SS wave moves across the country. it's not often you see a 2 sigma ridge building poleward like that

this is by no means a perfect setup, and it does need some work, but there is definitely heightened potential for a larger event here given the overall pattern
