A low pressure system developed in the western Gulf of Mexico during the day on the 28th. It slowly moved eastnortheast and by Sunday morning the 30th was located near Apalachicola Florida, not too far from the location of the January 25th storm. Unlike the previous storm, this one tracked farther to the west and moved northeast along the Atlantic Seaboard. By the morning of the 31st, it was located near Boston, Massachusetts. The farther westward storm track permitted warm air near the surface and aloft to move into Pennsylvania, particularly the Philadelphia area during the event. There was less cold air present at the start of the storm, especially nearer the coast.  Most of it was in the lowest layers of the atmosphere. This led to the more typical potpourri of weather across Eastern Pennsylvania with primarily snow in the Poconos and a wintry mix farther south and east. Precipitation started during the afternoon as snow throughout the state.  By early evening precipitation had changed to sleet and freezing rain around the immediate Philadelphia area, but the transition away from snow was painfully slow farther north and west as heavy snow continued to fall. Around 9 p.m. EST enough warm air had moved into the local Philadelphia area to change the precipitation to plain rain. Meanwhile a transition to sleet with some freezing rain was occurring in the Lehigh Valley and Philadelphia's far northwestern suburbs. As the low pressure system made its closest pass to the area during the evening, colder air started to return on its west side and the sleet changed back to snow in both Pottstown (Montgomery County) and Allentown (Lehigh County) after 10 p.m. EST.  Precipitation ended from south to north from midnight through 3 a.m. EST on the 31st.  Temperatures never made it above freezing except for the local Philadelphia area. Accumulations were highest in the Poconos where precipitation fell as snow throughout the event. The greatest accretion of ice, around one-third of an inch, occurred in the local Philadelphia area.  Untreated roadways were very treacherous and high traffic volume due to Super Bowl Sunday exacerbated the problems.  Within Philadelphia there were numerous minor accidents. In hilly Manayunk bus routes were either cancelled or rerouted. Chester County emergency personnel responded to about 20 vehicular accidents. Snow emergencies were declared in 8 municipalities in Montgomery County. The accretion of ice, snow and sleet downed wires and caused power outages to 5,000 homes and businesses in Philadelphia's suburbs. In Monroe County the heavy snow forced the cancellation of schools on Monday the 31st.Snowfall accumulations included: in Carbon County 6 inches in Albrightsville; in Monroe County 11 inches in East Stroudsburg, 10.6 inches in Bossardsville and 9.5 inches in Pocono Summit.; in Berks County 7.5 inches in Mertztown, 7 inches in Blue Marsh Lake and Hamburg and 6 inches in Bechtelsville; in Lehigh County 7 inches in Fogelsville and 6 inches at the Lehigh Valley International Airport; in Northampton County 8 inches in Williams Township and 6.8 inches in Bath; in Chester County 5.6 inches in Glenmoore, 4 inches in West Chester and 3 inches in Downingtown; in Montgomery County 6 inches in Palm, 5.5 inches in Pottstown and 2 inches in Wynnewood; in Bucks County 7 inches in Springtown, 4 inches in Sellersville and 2.1 inches in Furlong and 2 inches at the Philadelphia International Airport.
