you beat me to it, but this means i'm not just imagining things seems to have a better chance than either of the other two systems
starting to look the way Karen did in 2001 a few days before forming and appears to have in the last few hours a bit of banding and the convection trying to wrap around to the south and thickening
also, the frontal feature to the northeast is thinning out a bit and appears to be trying to seperate from the low

dont really want to forecast anything at this point, but wouldnt be surprised, as we did have something last year in april and december in this same general region
sum up: it has potential, but only about 48 hours to develop before moving over much cooler water
