Pittsburgh, Pennsylvania – Drivers across northern and western Pennsylvania could face slick and icy roads early Tuesday as a low-pressure system moves into the region, briefly allowing snow to change to freezing rain before warmer air arrives.
Weather system moving in overnight
According to the National Weather Service in Pittsburgh, precipitation is expected to move into the region after midnight Monday night. Snow will be the initial form for many locations, but a quick transition to rain is expected as temperatures rise.
The concern comes during the brief transition period early Tuesday morning, when some areas may experience a wintry mix that includes freezing rain.
Higher risk along Interstate 80 and elevated terrain
Communities along the Interstate 80 corridor and across higher elevations in northern Pennsylvania have a greater chance of seeing freezing rain. Even a thin glaze of ice could create hazardous travel conditions, particularly on untreated roads, bridges, and overpasses.
Elevated terrain in western Pennsylvania may also experience brief icing before surface temperatures climb enough to support plain rain.
Pittsburgh area expected to see limited impacts
Farther south and west, including the Pittsburgh metro area, snow is forecast to change over to rain relatively quickly. At this time, little to no ice accumulation is anticipated in the city and surrounding lower elevations.
Still, forecasters caution that conditions can change rapidly over short distances, especially during overnight and early morning hours.
Travel safety concerns
The primary risk window appears to be late Monday night through early Tuesday morning, when temperatures hover near freezing in northern counties. Motorists traveling during this period are urged to take extra precautions.
Drivers should:
- Reduce speeds and avoid sudden braking
- Increase following distance
- Watch closely for icy patches on bridges and shaded roadways
- Be especially cautious in higher elevations and rural areas
Advisories and updates possible
Winter Weather Advisories may be issued if confidence increases in the extent or severity of icing. Forecasters expect to refine the forecast as the system moves through the region early Tuesday.
Residents and travelers are encouraged to monitor updated forecasts and road conditions before heading out, particularly if traveling through northern Pennsylvania overnight or during the Tuesday morning commute.
