Natural Zamboni
Instead of cratering, the mercury—yes, we still have an old-fashioned, toxic but accurate, maximum-minimum thermometer—rose overnight, and when I finally got out for a walk, it was in the 40s. All the snow had melted, included the white that had coated the millpond, and the result was a sheen of water atop what had been solid ice. Call it Nature's Zamboni, the sans-engine equivalent of the marvelous machine designed to resurface skating rinks. The relative warmth is forecast to be short-lived; that thin layer of moisture will shortly be frozen back to smooth ice. If the deep freeze persists, the local skaters will be very, very happy.
