As you can see, rain is changing over to snow as the surface cold front moves towards Prescott this morning. Temperatures have dropped because of the advancing of the cold front and the moderate to heavy rainfall the past couple of hours. Expect rain/snow mixed today with the possibility of 1-3” of snow accumulation by this evening. Temperatures will not drop below freezing during the day, but roads may still become a bit slushy.
Expect partial clearing this afternoon or evening, but with some lingering snow showers. Some additional light snow accumulation is possible tonight and temperatures will likely drop below freezing, so there could be some some slick areas on the roads for tomorrow’s commute.
