The differences in the general evolution on the models are minor at this point, but overall qpf output and the exact location of jacks and subby zones mean a lot.
Then of course, way out of its range but the HRRR actually dryslots Dendrite, almost gets PF into the mid levels, and is close to giving half of CT an ice storm.
Yeah, but it always takes a while no matter what for them to really hone in on something. When you look at the 12z runs, they are in really good agreement.
