Light snow fell across Cape Cod and southeastern Massachusetts Wednesday morning, and set down coatings to around 1 inch of snow for some. The snow is gone in the afternoon and we are left with partly cloudy skies and cold temperatures. Highs Wednesday will be stuck in the 20s to low 30s with most spots not even hitting freezing. This is just a tease compared to what is coming for Saturday.
Our weather remains quiet Wednesday night as temperatures drop to the teens and 20s again. Black ice may make roads slick for Thursday morning’s commute. High temps rebound a bit to the upper 30s as our wind direction shifts slightly from the southwest and we see more sun.
