A cold blast is set to hit central Pennsylvania next week, with temperatures expected to plummet. The National Weather Service forecasts dangerously low conditions, as Arctic air sweeps across the region. In much of our area, highs will only reach the teens and twenties, with a low of -3 degrees on Monday. Wind chills could make it feel like -20 to -30, creating risks for frostbite and hypothermia. Everyone is being advised to take precautions and limit outdoor exposure. Snow accumulation though, will be minimal, with only light snow expected this weekend.
