    Purple Pittsburgh Power Plant-Effect Snow

    Yesterday I talked about what (some meteorologists said) was apparently pond-effect snow (formed like lake-effect snow). Today, CIMSS has posted an incontrovertible image showing that there was such a phenomenon -- but I'm still not convinced that all the snow tracks that fell in the Midwest yesterday were because of ponds.

    Last night, another type of water-effect snow fell -- and this was produced from steam via the Beaver Valley Nuclear Power Plant near Shippingport, Pa. (outside of Pittsburgh), according to the NWS there. It was very low in the atmosphere and, if it were farther from the radar, we wouldn't have even see it.
