What Pittsburgh Weather Means Today
Pittsburgh weather refers to the local pattern of cold, often snowy winters and rapidly changing conditions that can swing from rain to snow within a day. In December, typical highs are near 40°F and lows cluster around the freezing mark, creating a frequent risk of snow, freezing rain, and icy surfaces that affect commuting and outdoor plans.[5][1]
Today, that seasonal pattern is visible in lingering snow impacts from a recent winter system and a surge of very cold air behind it. While the heaviest widespread snow has ended, forecasters still point to localized snow bands north of the city and subfreezing temperatures that keep roads, sidewalks, and elevated surfaces slippery, especially during the busier travel periods.[3]
Snow and Cold: Travel and Safety Impacts
Recent winter weather has brought several inches of snow to parts of the Pittsburgh region, with advisories and warnings issued as totals increased and visibility dropped.[2][3] Although the broad storm has moved on, narrow lake-effect snow bands north of Pittsburgh may still produce additional accumulations through Monday, particularly near I-80, keeping some secondary roads and rural routes snow-covered or slick.[3]
Behind the storm, much colder air is moving in, prompting a Cold Weather Advisory for ridge communities with wind chills as low as -10°F to -15°F and even lower in the coldest spots.[3] Even within the city, a combination of subfreezing temperatures and gusty winds pushes wind chills near or below zero, intensifying the cold and increasing the risk of frostbite and hypothermia for anyone spending extended time outside without proper winter clothing.[3]
December Patterns and What to Expect Next
Climatological data show that December in Pittsburgh averages just above freezing overall, with typical highs in the upper 30s to low 40s°F and lows in the 20s°F.[5] Forecast services highlight that this month tends to feature frequent precipitation, including multiple snow days and periods of freezing rain, so residents can expect a mix of cloudy, damp, and snowy days rather than prolonged dry stretches.[1][5]
For the rest of December, outlooks suggest continued cold with several more chances for snow and wintry mix.[1][5] Because temperatures often hover near freezing, small forecast changes can decide whether a particular system brings mostly snow, icy conditions, or cold rain, making it important for people in and around Pittsburgh to follow daily updates from trusted local and national weather providers to plan travel, school activities, and holiday events safely.[2][3][4]
