This is my favorite weather condition from a logophile point of view, but my least favorite from a practical point of view. It's raining/sleeting/snowing now; we're all home safe, but I think the streets will be covered in ice tomorrow (and already are west of here).
We call this temperature (right around freezing, with precipitation) the Stevens temperature. Many years ago, I did the 'cross race at Farmington, and 'cross legend Tom Stevens delivered a disquisition to Ed in the pit on which bike parts, based on metal type, attract snow at various temperatures just around freezing.
I miss that course.
