High northerly winds are pushing bitter cold into the Pittsburgh region, threatening to sink the mercury to its lowest level of the season.
Bob Davis, a meteorologist with the Moon office of the National Weather Service, said the ushering in of the inclement weather began when a wind advisory was issued until 11 a.m. Sunday.
While the high winds were to dissipate, they are leaving in their wake drastically falling temperatures.
"It's going to be really noticeable," Mr. Davis said, noting that temperatures early Sunday hovered around 48 degrees. Those numbers dropped to the upper 20s Sunday afternoon and were expected to continue downward to single digits tonight, then getting only colder on Tuesday. "There's going to be a push of arctic air. The high temperature for Tuesday could be just 11 degrees. It will be bitter. With wind gusts of 15 to 25 mph, we could have wind chills of 15 to 20 below zero on Tuesday morning," Mr. Davis said. The low temperature tonight into Tuesday is expected to be 4 degrees.
Little is expected in the way of precipitation in the coming days, he said. Accumulation could be between 1 to 2 inches today.
"The big weather story for Pittsburgh will be the cold," Mr. Davis said.
