Thanks! I have more ETA data that I will be adding shortly. It amazed me that the AVN was STILL as far south as it was as late as 12z March 4th, considering how much the ETA had already jumped. Unfortunately, I don't have any MRF data, which would've been really cool for the 00z March 3rd run that I just added. I think as Chris said a few years ago, the best forcing was further north with the phasing PV lobe, as that was where the better dynamics were, and as that phase trended north and sloppier, a still somewhat south track of the 500mb low wasn't enough to take the forcing and explosive cyclogenesis with it, like it had on previous runs.
I still wish this verified
