Monday morning when I left my house it was in the upper 60s (I probably left home around 9:45) and I considered not wearing a coat (totally didn’t check the weather). When I left work I was rather glad to have a coat because it was in the teens and snowing. Because it had been warm earlier in the day the roads were icy with snow that had melted and refrozen. I saw a snow plow on my way home, but I think it was just spreading grit because the snow wasn’t building up and still hasn’t really accumulated tonight (Thursday).
Monday night may have been the warmest temperature I’ve been out in since temperatures dropped. Tonight when I left work my car had a hard time starting (even with a battery that was new last spring), so when I got home I wasn’t surprised to see that the temperature was negative.
