The unseasonably warm weather the past few days in Western Pennsylvania didn’t break any records for November, but they are certainly giving residents a chance to enjoy the outdoors before winter begins to set in.

Temperatures Monday reached 75 degrees and Tuesday’s high is forecast at 77 degrees.

“This last bout has been due to a large high-pressure system over the eastern part of the country,” said Pat Herald, a National Weather Service meteorologist in Moon Township. “It’s caused by low pressure in the West.”

It won’t last much longer, though, Herald said.

“The high is eroding as we sit here and talk,” he said Wednesday afternoon. “There’s a front coming out of the Midwest, a low-pressure system centered today over the Dakotas.”

Herald said that system is expected to push eastward overnight, “and we’ll get increased rain chances and lower, more seasonal temperatures later in the week.”

Rain is forecast for Veterans Day. By the end of the week, temperatures are expected to sink to the mid- and low-50s.
