What happened

The episode as NWS PHI wrote it up.

Snow showers that occurred preceding a cold front helped produce slippery conditions and numerous accidents during the morning commute across eastern Pennsylvania from Bucks County northward through the Poconos. Reported accumulations were all less than one inch, but the lack of snow so far this winter, the change in road conditions (since the snow showers did not affect all areas) and the confluence with the morning commute contributed to an abnormal increase in the number of accidents.|In Monroe County, eastbound Interstate 80 was closed from 530 a.m. EST through 300 p.m. EST after a multiple tractor-trailer accident. The first tractor-trailer jack-knifed. A second tractor-trailer could not stop in time and struck the first tractor-trailer and caught on fire. A third tractor-trailer veered off the interstate to avoid the collision and went down an embankment. All three drivers were injured and hospitalized. Traffic was detoured onto Interstate 380 and Pennsylvania State Route 940. Commutes took three times longer than normal. Schools had delayed openings.|There were also several accidents on Pennsylvania State Route 33 in both Monroe and Northampton Counties. There were delayed school openings in Northampton County also. In Northampton County, accidents were reported in Palmer and Upper Nazareth Townships. In Bucks County, many accidents occurred along U.S. Route 13. |Actual accumulations included 0.7 inches in Warminster (Bucks County), 0.4 inches in Feasterville (Bucks County), 0.3 inches in Macungie (Lehigh County) and the Lehigh Valley International Airport and 0.2 inches in Tannersville (Monroe County).
