Pittsburgh and its surrounding areas are in for a chilling and snowy start to the week, as stated by the National Weather Service in Pittsburgh. A light snowfall that graced the city this morning will taper off this afternoon, but not without the potential for "convective bursts of moderate snow," which could lead to treacherous travel conditions, should they occur. The afternoon could see snowfall rates between 0.5 and 1.0 inches per hour, particularly north of Pittsburgh around 1 PM, according to the National Weather Service’s Area Forecast Discussion.
In addition to the snow, a biting cold will blanket the region, with a Cold Weather Advisory and an Extreme Cold Warning set to take effect tonight through Tuesday morning. The onslaught of arctic air will drop temperatures into the single digits by sunset in northwest PA, and could plunge below zero along the I-80 corridor, with wind chills forecast to hit 10 below zero or colder for most of the area on Tuesday morning. The National Weather Service warns that these conditions, breezy overnight, could make it feel worse, with wind chills in Eastern Tucker County, WV, expected to plummet to around 25 below zero. In light of these conditions, residents are advised to brace for potential infrastructure issues late in the week as the cold extends its stay.
The wind is also a cause for concern, particularly in Eastern Tucker County, WV, where wind gusts of 50 to 60 mph are possible today. A Wind Advisory is in effect through midnight due to strong gusts exceeding 46mph, resulting from the stiff pressure gradient across the area. According to the National Weather Service, the high winds are a near-certainty in Canaan Valley, with probabilities staying above 80% for the majority of the day.
Looking at aviation conditions, snow throughout the morning has led to mainly MVFR (Marginal Visual Flight Rules) visibility, but flying conditions should improve slightly later in the day. Pilots can expect gusty west winds following a frontal passage with speeds around 15-20 knots, and occasional gusts reaching 30-35 knots. The forecast indicates a return to VFR (Visual Flight Rules) conditions on Tuesday under high pressure, but MVFR conditions and snow could return by mid-week with another cold front on the way, as suggested by the National Weather Service’s aviation outlook.
Travelers and residents across the area should take note of these warnings and advisories, ensuring they prepare for sub-zero wind chills and hazardous travel conditions for the coming days. For more detailed weather updates and advisories, individuals should keep an eye on the National Weather Service Pittsburgh PA website.
