With a full phase there's nothing to stop a primary surface low from tracking to southern Ontario. The mid-level lows are well west of us. Several EPS members were even more amped than the 0z ECM OP. On tonight's runs this is starting to look like a supercharged SWFE. I'm really curious if this keeps trending in the same direction or adjusts back in the opposite direction with a less-clean phase. I prefer the longer-duration event where we stay on the cold side even if it means less QPF.

Could be just a minor over correction to the north.

agreed plus less QPF will mean colder temps and ratio's higher to compensate for less QPF
