People stroll in the warm weather near Central Market in Lancaster on Saturday, January 11, 2020.

Those relishing in the unseasonably mild temperatures of late are in for a rude awakening.

Come Friday, temperatures will plunge back into the 30s, and there’s a chance of snow Friday night into Saturday, Millersville University meteorologist Eric Horst said.

“Where’s winter?” Horst said in a tweet Monday. “It’s going to make a … comeback at the end of this week.”

Daytime temperatures, however, will remain above average in the high-40s, low-50s through Thursday, Horst predicts. That’s following record warmth this past weekend, when high temperatures reached a balmy 65 degrees.

The average high temperature for mid-January is 38 degrees, Millersville’s weather records show.

Horst’s forecast shows the high sharply dropping from 50 degrees Thursday to 36 degrees Friday, setting the stage for a possible “plowable snow/mix storm” Saturday, Horst said.

The National Weather Service predicts snow to start before daybreak Saturday followed by a dangerous mix of rain, snow, freezing rain and sleet into the evening. There’s an 80% chance of precipitation, the service said.
