On the Isle of Lewis, Scotland, Eunice Clarke (Member 14,190) saw a woolly beast shaking off the snow. There were some sheep present also.

The mammoth Cumulonimbus storm cloud was shedding the last of its snow in the form of a microburst. This is a powerful column of sinking air. While air is always dragged down by a heavy shower of precipitation, it is given an extra downward boost when drier air below causes some of the shower’s moisture to evaporate or sublimate (change directly from solid ice into gaseous water vapour). A change of state like that can cool the air rapidly enough to make it plummet with sudden force. Eunice kept her distance. So did the sheep.
