School delays are piling up for Monday morning as the Pittsburgh area braces for another bitterly cold night, but one coming at the start of a week with a modest warmup in store.
A cold weather advisory from Allegheny County north, including Westmoreland, Armstrong, Butler and Beaver counties, is scheduled to run from 10 p.m. Sunday through 10 a.m. Monday, National Weather Service meteorologist Matt Brudy said.
Lows in the Pittsburgh metro area are expected to get down to -7, while outside the urban area they could reach -12 to -15, he said.
With winds lighter than they have been the last several days, the wind chill will not be a factor, Burdy said.
Pittsburgh Public Schools is among districts announcing two-hour delays for Monday morning. A complete list of school delays is available online from TribLive news partner WTAE.
The forecast high for Monday is 29 degrees.
Tuesday looks to be the warmest day of the week, with high temperatures for the Pittsburgh metro and surrounding areas in the 40s and areas south of Interstate 70 possibly touching 50, Burdy said.
While that won’t last very long, highs the rest of the week are expected to be closer to normal, with highs the rest of the week in the low 30s. By the end of the week, lows will be in the teens, but not below zero, Burdy said.
There is not yet any concern about river flooding from ice melting, Burdy said. A significant warmup of 40 to 60 degrees over several days, along with rain, would trigger that.
There is only a slight chance of precipitation late Tuesday into early Wednesday, which Burdy said could see flurries mixed with rain.
