Midweek Temperature Swing
By Thursday, temperatures jump more than 20 degrees compared to the start of the week. This rapid change supports rain rather than snow, though colder overnight lows could briefly mix precipitation types in some areas.
Unsettled Holiday Setup
As Christmas approaches, Pittsburgh remains under a pattern of cloud cover and mild air. Rain appears more likely than snow, but temperatures close to freezing overnight could still affect travel during early mornings.
What This Means for Residents
- Commuters: Expect slick conditions early in the week and wet roads later.
- Outdoor Plans: Cold weather dominates initially, but midweek warmth offers brief relief.
- Travel Planning: Monitor daily changes, especially around December 18 and December 23 when rain chances increase.
