If the H850LP gets anywhere near Central PA North, CNY is toast as far as a mix or changeover is concerned but the one thing we have going is the warmer temps get somewhat shunted Eastward but if its stronger, look out. I dont trust any system this yr TBH because the warmth wins over, most of the time at least here in CNY but I hope I'm wrong. If when you wake up and its already a mix we're toast, lol!
