This Euro outcome makes more sense given the broader longwave pattern. The mean ridge is on/off the west coast. That's not Position A for a MECS. The earlier MECS outcomes were predicated on perfect phasing/wave spacing. A very tough thread the needle. With so many waves in the flow, it makes more sense that you have a single wave driving the bus to create a storm rather than complicated wave interactions. So, with that in mind, this Euro outcome is quite nice still. I think @WinterWxLuvr mentioned earlier that the outcome now depends on the northern stream shortwave and that looks right to me given the 12z suite. Deeper and we get a Euro like outcome. Flatter/progressive and it's the GFS.
