Harrisburg, Pennsylvania – Below-average cold temperatures are expected to persist across much of the Middle Atlantic region through the coming week, increasing the potential for river and stream ice growth.
According to the National Weather Service Middle Atlantic River Forecast Center, colder-than-normal conditions are forecast to remain in place through at least the 6–10 day outlook period, valid through February 10. Temperature outlooks indicate much of the eastern United States, including Pennsylvania, Maryland, Virginia, West Virginia, and surrounding states, will continue running below seasonal averages.
Forecasters note that the persistent cold will allow rivers and streams to continue developing ice, particularly across inland and higher-elevation areas. Ice growth can lead to localized impacts, including restricted water flow and an increased risk of ice-related issues if future warming or precipitation occurs.
While no immediate flooding concerns are indicated, officials emphasize that prolonged cold sets the stage for potential ice movement later in the season, especially along major waterways and tributaries.
Transportation impacts may also continue, particularly during overnight and early morning hours. Motorists traveling along Interstate 81, Interstate 95, Interstate 76, Interstate 64, and Interstate 70 may encounter icy patches on bridges, overpasses, and untreated secondary roads as temperatures remain below freezing for extended periods.
The cold pattern may affect daily routines for commuters, students, and outdoor workers, while also increasing heating demand across the region. Snow and ice already present on the ground are expected to melt slowly, prolonging winter travel conditions.
The National Weather Service advises residents to remain aware of changing conditions and to use caution near rivers and streams where ice may be unstable. Ice thickness can vary significantly and is not safe for recreation.
Officials will continue monitoring river conditions closely and provide updates if the risk profile changes as the pattern evolves.
