Latest PA Snowfall Estimates, Timing For Sunday Storm

EASTERN PENNSYLVANIA — A fast-moving coastal storm is expected to drop 3 to 4 inches of snow in Eastern Pennsylvania on Sunday. The storm is expected to last through the afternoon, with snow stopping by 4 p.m.

Forecasters early Sunday slightly reduced the estimated snowfall totals expected from the storm. The estimates were downgraded after overnight temperatures were warmer than predicted, forecasters with the weather service said.

Snow rates of 1 to 3 inches per hour are possible at times in the heaviest snow bands on Sunday morning. "This may result in treacherous driving conditions," the National Weather Service warned.
