For tomorrow:

Deep layer shear is important. Yes, shear vector orientation is favorable WRT to the dryline and winds veer with height.

20-30 knots of deep layer shear, even with large instability, does not favor (sustained) supercell storm modes. Rapid clustering/mergers likely pic.twitter.com/Eg4JFQMpf6
