While Saturday will be clear with temperatures in the 30s and 40s, we start to see conditions shift around 3 am Sunday. With these cold temperatures locked in place, we’re tracking the chance for some winter precipitation arriving early Sunday morning.
A warm front will bring steady rain through the Ohio River Valley and into the Mid-Atlantic by Sunday.
