Scranton's Valley Winter: Elevation Snow and Lackawanna Winds
Snow in the Lackawanna Valley is a tale of two elevations — the valley floor around Scranton and the ridges of the Moosic Mountains can live in different storms.
Scranton's weather is written by its valley. The city sits in the Lackawanna River valley at roughly 750 feet, ringed by the Moosic Mountains and the ridges toward Clarks Summit and Montage Mountain, and that bowl shape means winter precipitation here is intensely local: a storm can dust Green Ridge while the higher ground in Dunmore and the Abingtons, a few hundred feet up, picks up several inches.
The numbers set the baseline. Climate normals for the Wilkes-Barre/Scranton area put the average annual snowfall in the mid-forties of inches, concentrated from December through March, with January and February the coldest months — average highs only in the mid-30s and lows near 20. November is the on-ramp: average highs slide from the mid-50s toward the 40s, the first measurable snow typically arrives, and the valley's many shaded hollows start holding their cold.
Elevation is also why the region's ski season lives where it does. Montage Mountain, rising southeast of the city, catches and holds snow that the valley floor loses to a marginal temperature — the same storm can be rain on Lackawanna Avenue and a powder day on the slopes twenty minutes away.
Preparation in the valley follows the map: know your elevation, expect the ridges to ice before the floor, and give the President Biden Expressway and I-81's grades through the notch the respect that altitude earns. In Scranton, winter does not arrive evenly — it arrives by altitude, street by street.
The Lackawanna River adds the valley's other winter signature: ice forming along the banks in the coldest stretches, and the first thaws watched as carefully as the snow itself by the boroughs downstream in Old Forge and Duryea.
