Pittsburgh, Pennsylvania — Snow squalls are expected to develop across western Pennsylvania Monday afternoon and evening, creating hazardous travel conditions that may develop rapidly, according to the National Weather Service in Pittsburgh.
Forecasters said snow bands and snow squalls are expected to move into the region during the afternoon and evening hours, with the highest impact window between 3 PM and 8 PM. During this period, bursts of snow could quickly coat roadways and sharply reduce visibility, especially as temperatures fall below freezing.
Snow squalls are intense but short-lived bursts of snow accompanied by gusty winds, often lasting one to three hours. While total snowfall amounts may be limited, the rapid onset can create whiteout conditions and cause road conditions to deteriorate within minutes. The National Weather Service noted that these events have a long history of being associated with serious and sometimes deadly traffic accidents.
Hourly snowfall rate projections show brief periods where snowfall rates approach or exceed a few tenths of an inch per hour, particularly during the late afternoon and early evening. Even these short bursts are enough to make untreated roads slick, especially on bridges, overpasses, and higher elevations.
The National Weather Service urged motorists to exercise extreme caution. Drivers are advised to avoid or delay travel when snow squalls occur. If caught in a squall, officials recommend reducing speed, turning on headlights and hazard lights, and exiting the roadway if possible until conditions improve.
Because snow squalls can develop quickly and with little advance warning, residents across the Pittsburgh region are encouraged to remain weather-aware throughout the afternoon and evening commute. Conditions may improve just as quickly as they worsen, but the sudden nature of snow squalls makes preparation and caution critical.
Travelers should monitor updated forecasts and road conditions closely as the evening progresses.
