PITTSBURGH — Another blast of winter to start your week and it’s going to stick around. Watch area roads heading out the door Monday as quick shots of heavier snow showers overnight has left many untreated roads covered and slick. Snow showers will wind down during the day Monday. However, additional light accumulation is possible in any snow showers. Dangerous travel continues due to blowing snow and whiteout conditions in the ridges and mountains where a Blizzard Warning is in effect through Monday afternoon. It will be unseasonably cold for this time of the year with temperatures struggling into the mid 20s on Monday. High temperatures will stay in the 20s much of the week, running 10-20 degrees below normal. Low temperatures Monday night and Tuesday night will fall into the single digits in much of the area with wind chills below zero early Tuesday morning.
