Fans headed to Lowe's Motor Speedway for Friday night's and Saturday night's racing might have to deal with rain, but the fog that shrouded the Charlotte metro region early Friday was expected to dissipate.
Steamy dewpoint temperatures were helping create the fog, and visibilities dropped below one mile at several airports in the Charlotte region. The fog was expected to give way to mostly cloudy skies, but occasional sunny periods were forecast.
Sprint Cup practices in advance of Saturday night's all-star race were scheduled Friday at the track in Concord, along with practices and qualifying for Friday's event in the NASCAR Truck series. That race was scheduled for 8 p.m.
Showers and thunderstorms were expected to develop across the region Friday afternoon.
Never miss a local story.
No severe weather is predicted, but forecasters say the storms will be slow-moving, so heavy rain and possible spotty flash flooding could be a problem later in the afternoon and Friday evening. High temperatures were forecast to reach 80 degrees.
Saturday's forecast is much the same, but the chances of showers and thunderstorms in the afternoon and evening might be greater than on Friday. A few sunny periods are likely in the morning, but the evening storms could be a problem for the NASCAR event at the speedway.
A cold front is forecast to cross the area Sunday morning, and that means a high chance of showers and storms, especially in the first part of the day.
Much cooler conditions are expected to arrive for Monday, with a gradual warming trend as the week goes on.
