I do have a question. I know ridge position during these MCS/MCV is important along with latent boundary's. I've just kind of noticed over the last 72 to 96 hours that here east of 65 and north of 70 we've had a long fetch paralleling lake Michigan. Meso analysis has consistently shown a bit of a more stable environment ie. lower dews, cape lines, 850 dew lines, really compressed - to + east to west along the fetch. For instance yesterday there was literally a wall of stability along 65 right in line with the winds off the lake all the way down to KIND before the boundary layer and storms spread to the SE. Does the lake have that much influence this far south or has it just been a coincidence with the position of the ridge over the southern plains?
