Winter Storm Warnings in Allentown, Pennsylvania
Nestled in the Lehigh Valley, Allentown sits in a part of Pennsylvania where winter weather can swing from a quiet dusting to a genuine nor'easter within a single season. Across the 13 years analyzed from 2012 through 2024, the city averaged 26.2 inches (66.7 cm) of snowfall annually — enough to make winter a real consideration for residents and travelers alike, but not so extreme that heavy events are routine.
The snowiest stretch of the year runs through February, January, and March, in that order, meaning late winter can be just as punishing as the heart of the cold season. Average winter overnight lows hover around 25.3°F (−3.7°C), keeping accumulated snow on the ground and roads for extended periods after a storm passes.
Significant snow events are relatively infrequent here. On average, Allentown sees roughly half a heavy-snow day per year, underscoring that when a winter storm warning is issued, it genuinely warrants attention.
A winter storm warning signals that dangerous snowfall, ice, or a combination of both is imminent or already occurring. It is the highest-tier advisory in the warning sequence. Keep in mind that the snowfall thresholds used to trigger these warnings differ by region — what qualifies in Allentown may not match criteria used in New England or the Deep South.
