The episode as NWS CTP wrote it up.
The coldest air mass in nearly two decades brought extreme cold temperatures and dangerous wind chills to much of central Pennsylvania from January 6-8. Temperatures bottomed on the morning of the 7th with lows ranging from 0 to -20 F with wind chills between -25 to -50 F. The most recent comparable, though colder arctic outbreaks occurred in January 1994 and 1996 respectively. The arctic cold outbreak closed schools, set or tied low temperature records and prompted Gov. Tom Corbett to issue a Proclamation of Propane and Heating Oil Emergency to waive federal and state motor carrier regulations related to hours of service for drivers of commercial motor vehicles transporting propane gas and heating oil in Pennsylvania. The extreme cold outbreak caused serious logistical problems associated with the distribution and delivery of propane gas and heating oil within the state.
