Monday started mild across the Pittsburgh region and ended as the snowiest 60-degree day on record, according to the National Weather Service in Moon.
“Most places got between 2 and 5 inches, but there were a couple of localized areas that got over 6,” said Bill Modzelewski, meteorologist. “Our office was one of the places that saw one of those heavier bands.”
Waking up to a half-foot of snow was a surprise to many.
Modzelewski said the initial forecast of 2 inches was guided by the thought that snow would melt on impact with warmer ground temperatures.
“Sometimes you get that base layer, and it just keeps it accumulating,” he said.
Yesterday was the snowiest 60°F day we've seen in our records (dating back to 1948). Out here in Moon Township, the high was 60 degrees and we measured 6.3" of snow. pic.twitter.com/Clj9YCz6Wv

Dozens of school districts issued a two-hour delay Tuesday, while some switched to remote learning after the heavier-than-expected snow.
Duquesne Light and West Penn Power continued to make progress restoring electric service in areas that lost power after weekend wind storms.
As of about 9 a.m. Monday, Duquesne Light reported about 3,840 customers out, down from 40,000 over the weekend. West Penn Power reported about 600 customers still without power in Allegheny County and about 400 in Westmoreland.
On-and-off snow showers were expected to continue Tuesday, with wind gusts of up to 30 mph blowing snow and re-covering roads, according to TribLive news partner WTAE. Pockets of heavier snow will fall with some areas picking up 1 or 2 inches.
A winter weather advisory is in effect for Westmoreland and Fayette, and some northern counties that include Clarion, Indiana and Venango through 5 p.m. Tuesday.
Tuesday’s high of up to 30 degrees will give way to temperatures in the 50s by Thursday, Modzelewski said.
“After we get through today, things should be quieter,” he said.
