A fast moving low pressure system brought  heavy snow to Eastern Pennsylvania on the 22nd. Accumulations averaged between 5 and 10 inches with the highest amounts in the Lehigh Valley and the Poconos. Snow began falling during the first half of the afternoon. Cold weather the previous two days made it easy for the snow to accumulate. Roads became slippery quickly as witnesses by Whitemarsh Township (Montgomery County) which reported thirteen accidents within the first half hour that the snow started.  In a similar situation to what occurred on the 5th of this month,  schools and businesses closed early and created an early rush hour. Numerous accidents occurred, about three times the normal number of crashes. Average commutes took three to four times longer than normal. The heaviest snow fell during the latter half of the afternoon and the first half of the evening. It ended around midnight that night.  In Carbon County, the Mansion House Hill road was closed as vehicles became stranded. Many schools were closed the next day (Friday the 23rd). In Northampton County, two tractor trailers became stuck on opposite sides of Pennsylvania State Route 378. Westbound U.S. Route 22 was closed because of an accident around cemetery curve. Cars were abandoned at the bottom of hills as people trudged home from there. Tractor trailers could not make up the hills within Allentown (Lehigh County) also.  Around Philadelphia, bus lines were cancelled in the hillier parts of the city and there were dozens of delays at the International Airport. Specific accumulations included in Berks County: 10 inches in Kutztown, 6 inches in Morgantown, 5.5 inches in Hamburg and 5 inches in Reading, in Bucks County: 8 inches in Springtown, 7.4 inches in Doylestown, 7 inches in New Hope and 6 inches in Langhorne, in Carbon County: 10.7 inches in Palmerton, 10.5 inches in Summit Hill, 9 inches in Lehighton, and 7 inches in Jim Thorpe, in Chester County: 8.1 inches in West Chester, 7.5 inches in Valley Forge and 7 inches in Westtown, in Delaware County: 7.5 inches in Media, 7.4 inches in Radnor and 6.7 inches in Clifton, in Lehigh County: 10.5 inches in Schnecksville, 10 inches in New Tripoli, 8.5 inches in Zionsville and 7 to 8 inches in Allentown, in Monroe County: 9.4 inches in Bossardsville, 8.5 inches in East Stroudsburg, 7 inches in Saylorsburg and 6.5 inches in Effort, in Montgomery County: 7.6 inches in King of Prussia, 7 inches in Huntingdon Valley, 6 inches in Palm and Ambler, in Northampton County: 10 inches in Forks, 9 inches in Plainfield and 8.3 inches in Bath and in Philadelphia County:  7 inches at the International Airport and 6.4 inches at the Franklin Institute.The low pressure system responsible for the heavy snow developed along the Red River Valley in the Southern Plains on Wednesday the 21st. By Thursday morning the 22nd, it was located over northern Alabama. It moved quickly offshore and by the morning of the 23rd, it was more than 300 miles east of the Delmarva Peninsula. The quick movement of the low pressure system prevented heavier snow from occurring. But it was compensated by a higher than normal snowfall to water equivalent ratio. In the so-called average snowstorm the ratio of snowfall to water equivalent is usually 10 to 1. For example, 10 inches of snow would melt down to about one inch of water (or rain).  In this storm, partially because the air mass over the region was considerably colder than normal, the snowfall to water equivalent ratio was closer to 20 to 1.
