Pittsburgh, PA – Freezing rain may lead to hazardous ice accumulation across parts of western Pennsylvania and nearby states on Friday, prompting continued concern under an existing Winter Storm Watch.
According to the National Weather Service in Pittsburgh, ice accumulations of one-quarter inch or more are possible within the Winter Storm Watch area, which includes portions of western Pennsylvania, northern West Virginia, and eastern Ohio. Areas just outside the watch could still see a trace to one-tenth of an inch of ice.
Forecast graphics indicate the greatest uncertainty lies in the timing of the transition from freezing rain to plain rain. If warmer air arrives more quickly, ice amounts would be lower. However, prolonged cold temperatures could result in greater ice accumulation, increasing the risk of slick roads, downed tree limbs, and power disruptions.
The ice accumulation forecast covers the period from 7 a.m. Friday through 7 a.m. Saturday, with freezing rain expected to be the primary hazard during that window. The National Weather Service noted that Winter Weather Advisories may be needed for areas outside the current watch area.
In a separate update Thursday morning, the National Weather Service reported showers and a few thunderstorms with small hail moving through the region early in the day, with activity expected to end by mid-morning. No changes were made to the Winter Storm Watch.
Residents and travelers are encouraged to monitor updated forecasts and prepare for potentially dangerous travel conditions, especially during the Friday commute.
