Swap out those sandals for a pair of mukluks.
A day after the temperature soared to 67 degrees, Pittsburgh and much of Western Pennsylvania were under a winter weather advisory and wind chill advisory that will continue into Thursday.
Rain began before 7 a.m. today with temperatures in the mid-40s, but that was expected to change -- dramatically -- as the day wears on.
Temperatures will begin to fall after 11 a.m. and the rain will change to snow around 3 or 4 p.m., National Weather Service meteorologist John Darnley said. Because of warmer surface temperatures, snow won't immediately accumulate on roads, but high winds will reduce visibility during the evening rush, he said.
"There's still going to be driving hazards," Mr. Darnley said.
The winter weather advisory was in effect from 1 p.m. today until 1 a.m. Thursday, with 2 to 4 inches of snow possible. Winds of 15 to 25 mph will gust to 45 mph at times, and with the temperature falling to near 10 degrees overnight, wind chills of minus-10 to minus-15 were forecast.
As an added treat, locations south of the Mason-Dixon Line may hear rumbles of thunder as a low pressure front moves through today, Mr. Darnley said.
Thursday's high will be in the mid-20s but Friday will bring another hint of spring, with temperatures rebounding to the lower 50s.
Northwest Pennsylvania was under a winter storm warning, with as much as 10 inches of snow possible.
