The s/w starts coming ashore around 12z. I think it’ll be more into the RAOB network for the 00z runs…if you’re into believing in that sorta thing in this day and age in weather modeling.
Anyway, that s/w has been digging into the SW and over the 4 corners region before coming out into the midwest. Over the last day or so there’s been another weaker northern piece that has been working in over the midwest. On most runs they’ve been lockstep and the system has been able to amplify some as it reaches our region. They seem a little more disjointed on the 6z euro…either it’s getting out ahead of the main s/w or the main one is lagging behind a bit. Either way it seems to be flattening the flow and not allowing the main s/w to amplify much and the whole thing remains more positively tilted as it reaches us. The end result is a much weaker/south system. Here’s the last 4 runs of H5 from the euro valid 3z Wed.
