PENNSYLVANIA — The 2026-27 winter outlook for Pennsylvania is shaped by a strong El Niño, one of the strongest on record for this time of year. The pattern is expected to influence nearly every part of the season, from snowfall and temperatures to heating bills and ski conditions. A review of every strong El Niño winter since 1957 points to the heaviest snow in the northwest and the Laurel Highlands, with lighter totals across the southeast.
Erie, Edinboro, and Warren Lead Pennsylvania Snowfall Outlook
The highest snowfall potential this winter is focused on northwest Pennsylvania, including Erie, Edinboro, Meadville, and Warren. This region sits in the top snowfall zone on the outlook map, where lake-effect snow off Lake Erie often adds to totals from passing winter storms.
The northern tier also shows above-average snow potential, covering Coudersport, Wellsboro, Towanda, Montrose, and Honesdale. Higher elevations and a more favorable storm track keep these areas among the snowiest parts of the state during the season ahead.
Laurel Highlands Including Somerset and Johnstown Stand Out in Southwest
A second zone of heavier snow appears across the Laurel Highlands, stretching through Somerset and toward Johnstown. Elevation plays a major role here, as the ridges of southwest Pennsylvania tend to squeeze extra snow out of passing systems.
Nearby areas, including Greensburg and Indiana, fall into a moderate snow zone. Pittsburgh, Beaver, and Washington sit in a band of somewhat lower totals, though the region could still see several impactful snow events through the winter months.
Central Pennsylvania From Williamsport to Allentown Falls in a Moderate Snow Band
A band of moderate snowfall stretches across central and eastern Pennsylvania, including Renovo, Williamsport, and the corridor from Pottsville toward Allentown and Easton. Scranton, Stroudsburg, and Milford also fall within a moderate zone in the northeast.
These areas could see a mix of snow and wintry events through the season, with totals depending heavily on the track of coastal and inland storms. A single big storm could make a major difference in final snowfall numbers across this part of the state.
Philadelphia, Harrisburg, and South-Central Pennsylvania Expected to See Lighter Totals
The lowest snowfall potential on the outlook covers south-central and southeast Pennsylvania. This includes Harrisburg, Lancaster, York, Gettysburg, Chambersburg, Reading, and the Philadelphia area, where milder air during strong El Niño winters often limits snow accumulation.
Snow lovers in these areas should not give up yet, as strong El Niño winters can still deliver a significant storm. Residents across the state should also plan ahead for heating costs and winter travel as the season approaches.
