The threat of freezing rain overnight has increased based on the latest forecast and observations.

As a result, the National Weather Service just issued a Winter Weather Advisory for the early hours of Tuesday (January 8). This is in effect for Mercer, Burlington and Bucks Counties.

"Based on the latest observations, conditions could be a bit colder overnight than previously forecast meaning freezing rain may occur farther south....potentially even affecting the I-95 corridor," the Mount Holly office of the National Weather Service wrote on Twitter tonight.

A Winter Weather Advisory means that "periods of snow, sleet or freezing rain will cause travel difficulties."

Mixed precipitation is likely in our area overnight. "Additional snow accumulations of up to one inch and ice accumulations of around one-tenth of an inch (are possible)," according to the National Weather Service.

"Plan on slippery road conditions during the overnight hours into daybreak," the advisory says. "The freezing rain will eventually change to plain rain from south to north before tapering off late Tuesday morning."
