Warming temperatures and weekend rain will not impact river conditions or travel much, according to the National Weather Service.
Temperatures will hover in the upper 40s Saturday with a 40 percent chance of rain, National Weather Service meteorologist Lee Hendricks said. As much as three-quarters of an inch of rain could fall, but it won't be enough to cause the ice to rise on the rivers or cause major travel safety issues.
Some portions of the Allegheny River, including an area in Armstrong County, are covered in large areas of ice.
The rain will continue into Saturday night and Sunday morning, when temperatures will be in the mid-30s.
Patches of ice are possible over the weekend despite above freezing temperatures because the ground is still frozen, Mr. Hendricks said. No traffic warnings have been issued.
