It was a bitter cold night last night. A bank thermometer in downtown Lehighton read 11 degrees below zero at 6 a.m. Unofficially, the lowest reading we received was from Lorraine Kunkel of Kriss Pines in Franklin Township, whose thermometer read minus 20. Roger Naratil, a dispatcher at the emergency communication center in Lehighton, said Bowmanstown had a reading of 17 below at 7 a.m. George Edwards tells us it was 14 below zero at Edward's Greenhouses in Tamaqua.
