Never experienced -17 without a wind chill. Originally from PA. From 2012 to 2014, in January months, we experienced temps in the range of -10 with a wind chill of -29. And major snow storms every holiday from Christmas to Easter (usually 12 to 36 inches). Needless to say, with the price of heating oil at the time ($5.50/gal) and the fact that it was getting more difficult for me to clear snow, we decided we had enough and began looking for a home in Florida. We moved to Florida in December of 2015, just in time for the winters to become milder in Pennsylvania
