Time for another investing metaphor. I'd say just follow your own rules. DEN/CYS chasers should probably get after upslope in the back yard. I prefer true DL systems but with a slow moving trough. Lead-up days offer more chances, which means a greater overall chance of success on the trip. Wyoming action this year is like the stock that got away. Changing rules based in it is like chasing stocks. However, WY does back up one valid rule. Get out there! Staying home offers near zero chance. Also my rules call for outflow boundaries. I would have missed Ensign, KS but I'm not changing my own rules. Again, if your own rules call for chasing upslope, do not change. It is kind of like value and growth investing. Both are valid methods, but they have very different rule books.
