The NASCAR Cup Series is set to run its annual event at New Hampshire Motor Speedway on August 23, with the green flag scheduled for 2:20 p.m. Eastern time.
Meteorologists from the National Weather Service predict a 27% chance of rain at the start, but that probability climbs to 57% as the day progresses, driven by an approaching line of storms.
Potential Impact on Race Duration
The speedway does not have permanent track lighting, meaning that if rain delays the event, the race could be cut short once darkness falls.
Temperatures are expected to hover in the low 70s, with winds around 6 mph, conditions that could make the track slick but not necessarily halt competition.
NASCAR has said it can deploy wet‑weather tires if needed, though the series will not run on a completely washed‑out surface.
The race will be broadcast on the USA Network, giving viewers a direct look at the unfolding weather challenges.
Location and Context
The track lies roughly 15 miles north of Concord and is situated north of the town of Loudon, placing it in a region prone to sudden summer thunderstorms.
While the event is part of the broader NASCAR schedule, it remains a key date for teams seeking playoff points and for fans who travel to the New England area.
