It's a really complicated pattern. It's a mix of the spring wavelengths still having cutoff tendencies, with a Nino look rapidly developing. So I'm not surprised with these troughs diving in almost N-S. Of course a degree of longitude with the placement means a difference of 65-70 or rain and 49 lol.
If I had to guess later tomorrow and into a chunk of Sunday is good from like BDR-HFD up into srn VT and NNE from there into nrn NH and adjacent Maine. Highest confidence I think.
