Sorry, I was living in So. Cal. then. But, yes, the ash cloud was probably large enough to effect the atmosphere this far downrange. There are various ash deposits in Kansas from ancient eruptions: Crater Lake, OR, Valles Caldera (New Mexico), Yellowstone Caldera, and the Long Valley Caldera, CA. Each of those make the Mt. St. Helens eruption look like a hiccup...
