Pennsylvania starts the morning in deep winter cold, with bright skies across western counties. The air bites sharply. The sidewalks crunch. Temperatures are hovering around 17 degrees, making today one of the coldest December mornings in Pittsburgh so far.
The cold subsides swiftly as the week goes on. Sunshine today helps temperatures rise into the mid-30s, providing some relief from the cold spell. Roads stay dry throughout the day, ensuring smooth driving throughout Allegheny County.
On Wednesday, warmer air continued to rise. Afternoon highs reach the low 40s, indicating a marked shift in the trend. Clouds build late, paving the way for altering conditions as moisture rushes in from the west.
Attention shifts to Thursday, December 18th, when weather conditions worsen. According to the National Weather Service, rain begins in the afternoon as temperatures reach 53 degrees. By dusk, colder air pushes back in, resulting in an overnight switch from rain to snow.
This shift increases the risk of slick roads, particularly on untreated surfaces. Bridges, overpasses, and shaded roadways may experience early icing as temperatures drop into the mid-20s. Drivers should allow extra time Thursday night and early Friday.
Snow continues throughout Friday morning, with a 60% probability of falling before tapering off later in the day. High temperatures struggle to reach the mid-30s, making slushy conditions probable on the commute.
The weekend looks calmer, but still wintry. Saturday is partly cloudy, with highs reaching 45 degrees. Sunday cools again, with a risk of light snow returning late.
Winter is setting in over western Pennsylvania, and conditions could change quickly as systems pass through.
