How snow days work in Maryland
There is no single Maryland snow day threshold, which is why this page scores each town separately. Hagerstown averages 33 inches of snow a year against Salisbury’s 8, and a district that plans for the first amount does not close for weather that would shut the second one down.
Each score compares what the National Weather Service is forecasting against that town’s own NOAA 1991-2020 snowfall normal, then adds weight for ice, wind and dangerous cold. Every number on this page links through to the full factor breakdown, because the reasoning is the part worth checking.
