What should be the approach of pilots in dealing with changing weather conditions, and what is the opinion on regulators and Medallion's performance?
Avoiding "iffy" weather is not a solution.  Weather changes fast.  Pilots must be equipped and possess the skills to deal with it.  Regulators would do well to acknowledge this and stop with all the cowboy vs choir-boy talk.  And giving Medallion more money is not going to help either, because Medallion sucks.
