The National Weather Service is predicting an end to the spring-like conditions over the past few days.

Beginning Monday evening, a rain/snow mix is expected to continue into Tuesday. 1-3 inches are possible in greater Glenside.

“One thing is for sure, this storm will start a pattern that brings colder, more active weather from the Midwest to the Northeast with reinforcing shots of seasonably cold air masses with the potential for some clipper systems to bring snow events,” AccuWeather Meteorologist Dean DeVore said.
