The "I" storms do seem to cause a stir. Iris Isabell, all both seemed to confound the models and media. I have to wonder if the timing of the storm has to do with the effects of the storms on the atmosphere before it. The atmosphere has to get into a certain mode in order to support a system of any kind and then relax into a different mode between storms. I wonder if the computer models ever do runs on what the relaxed atmosphere from post storm to post storm looks like so they could anticipate the effects of the storms in the culmination of a 9th+ storm.
