A cold front is expected to move through the region Wednesday night into Thursday, and remain near the area into Friday, forecasters said. Waves of low pressure are expected to ride along the front into the weekend, bringing multiple rounds of showers and thunderstorms, with the greatest chances of storms on Thursday.

The National Weather Service's Mount Holly office issued a Level 2 flash flooding threat for Thursday, covering the period from noon to 9 p.m. Rainfall rates of 2 to 3 or more inches per hour are possible, which could lead to flash flooding of urban areas, poor drainage areas, creeks and streams, according to the forecast.

"Flash flooding could result in disruptions to travel for the evening commute. Some roadways may become impassable," the National Weather Service said.

Forecast confidence on the timing and details of Thursday's storms remains low, according to the agency.
