You were extra cold getting your paper this morning, weren't you?
Fear not. The day will warm up, but an arctic front this week will make it feel like 30 below.
The wind chill will make this zero-degree morning feel like minus five-to-15 degrees, National Weather Service meteorologist Brad Rehak said. A wind-chill advisory remains in effect until 11 a.m. By evening, it will feel about 10 degrees, though the high will peak in the mid-20s.
"It's going to be a brief warm up until another arctic front comes through Monday," he said.
Monday night into Tuesday morning, temperatures will fall to minus 10, with a wind chill making it feel like 20 or 30 below. Tuesday afternoon will peak between zero and five degrees.
Less than an inch of snow today is expected to pile onto Saturday's 5.2 inches that fell in the Pittsburgh area. An additional inch or two fell northeast and east of Allegheny County, Mr. Rehak said.
Pittsburgh public works crews' 12-hour shifts started Friday night to treat roads and plow, mayoral spokeswoman Sonya Toler said.
During the day Saturday, 50 trucks and five tractors plowed Pittsburgh's 1,208 miles of streets, she said. An additional 10 trucks were added till 10 p.m. Through 4 a.m., 56 trucks were on duty.
Overnight, the Public Works Department spread a combination of liquid calcium and rock salt, which can make salt effective to zero degrees, Ms. Toler said. Because of the low temperatures, though, it may not be completely effective until the morning.
"For this reason, we are urging extreme caution on the roadways," she said in a statement.
