i think this window has a more mature pattern where the block isn't quite as oppressive... the 50/50 is in the spot it "should" be in, so the risk of completely squashing something is lower
i would urge caution at this point given that it’s just one run with a jump like this but the 12z GEPS also shot north and the ICON had a similar evolution with a lobe of the TPV tilting the trough
honestly, even if this amps more and confluence ticks north, there's enough cold in place that I don't see how you guys wouldn't at least get a front end +SN thump to usher in the pattern. the antecedent airmass is very cold
