Winter Weather in Fayette Ridges, Pennsylvania

Four inches fell at Ohiopyle, while 2.5 inches was reported near Farmington.

While surface low pressure tracked from the southeast CONUS off of the Mid-Atlantic coast on January 15th and 16th, an upper-level shortwave trough dug from the Upper Midwest into the Upper Ohio Valley. While moisture overall was not excessive, snow accumulation was highly efficient thanks to sufficiently cold temperatures and upward motion in the dendritic growth layer. This led to an accumulation of several inches across the region.
