Jeff -- I have to disagree. Working at MF in 2004, we could run the ride in a steady rain as long as it was not heavy. I remember rainy days where we never went down. The policy on MF is to now go down for any sort of rainfall. In addition, Opening Day at Maverick it was clear that it was cleared to run in the downpour that occurred that morning (the same downpour that is the cause of the Magnum incident). After that incident, Maverick now must either go down, or transfer off trains for any type of rain. And although they aren't the best source of info, I have heard this from multiple Ride Ops.
Although these are the only coasters that I know the policies for sure, I have noticed others have followed in similar fashion. (Mantis went down for the same sprinkle on Sunday). As a side note, the sprinkle on Sunday was an isolated blip on radar. There was no other activity within 100 miles of the park.
Bottom line, I don't know how you can say "there are no "new policies" being enforced", when, at least to me, it's pretty clear that there are. Now I will say, that we must be careful not to assume how the policy is carried out (ex: 5 empty trains after the rain stops), because this has been very inconsistent, but it is obvious there is a new "standard" for ride operations in the rain.
Finally, since it seems you know, I am curious as to what weather equipment the park actually has. I know of the anemometers on many of the taller rides, and I know that Park Op uses the CLE NWS Doppler radar for monitoring incoming storms. But do they have additional equipment on site?
