Summary: On Friday, the axis of an upper-level trough will be just to the West of New Hampshire.  The trough combined with a stalled front over the region will lead to scattered showers throughout the day. Overnight, the trough axis will move east of the region.  On Saturday, zonal flow will dominate the pattern but the stationary front will still be in place.  Stronger flow off the Atlantic Ocean will lead to showers and thunderstorms throughout the day.  On Sunday, a robust upper-level trough will make its way over the great lakes region, leading to large amounts of upper-level divergence.  The stationary front will transition into a warm front associated with an approaching low pressure system from the west and move North. Some scattered showers and thunderstorms are possible throughout the day on Sunday in the warm sector. We will continue to update the forecast throughout the week.

New Hampshire Motor Speedway is a 1.058-mile (1.703 km) oval speedway located in Loudon, New Hampshire, which has hosted NASCAR racing annually since 1990, as well as the longest-running motorcycle race in North America, the Loudon Classic. Nicknamed “”The Magic Mile””, the speedway is often converted into a 1.600-mile (2.575 km) road course, which includes much of the oval.

The track was originally the site of Bryar Motorsports Park before being purchased and redeveloped by Bob Bahre. The track is currently one of eight major NASCAR tracks owned and operated by Speedway Motorsports.

The track length is disputed by the two major series that run at New Hampshire. The NASCAR timing and scoring use a length of 1.058 miles (1.703 km). The IRL timing and scoring use a length of 1.025 miles (1.650 km).
