PITTSBURGH — It will be another cold night with temperatures down to near 20 degrees.
Plan on having your coats Tuesday with highs only in the 30s. There should be a mix of sun and clouds Tuesday until the evening when clouds thicken again.
As a weak wave and cold front push through, we'll have a chance of light snow showers or flurries.
