Much of western and northern Massachusetts received the first snowfall of the season this evening. Here in Concord, we are right on the snow-rain line with the temperature hovering right around 32°F. Even though the forecast indicates that precipitation will continue through the night, it is anyone’s guess what form it will take. I decided to clear the inch of accumulated icy slush at 10 pm as a hedge against it turning into a frozen mess by morning. I have learned from experience that snow blowers work well on fluffy snow, passably with slush, and are of no use against ice. If the temperature remains above freezing throughout the night, then my work will have been for naught. If it dips below, I will be happy for the preemptive effort.
