WEATHER UPDATE — The weather in Las Vegas is miserable right now, with light rain falling and temperatures in the low 50s. But the poor weather should only be a factor for today. According to the National Weather Service, there is a 70 percent chance of rain today, but that drops to 20 percent tomorrow and zero percent for Sunday’s Kobalt Tools 400 at Las Vegas Motor Speedway.

There are 44 cars entered for Sunday’s NASCAR Sprint Cup race, and if qualifying is rained out, the only driver to miss the race would be Mike Bliss.

Congrats to NASCAR Sprint Cup veteran AJ Allmendinger, who will race in the Indianapolis 500 for Roger Penske and at least one other IndyCar race this season, it was announced this morning.

The ‘Dinger had a great run in Phoenix last weekend, where he drove the low-budget No. 51 Phoenix Racing Chevrolet SS to an 11th-place finish. Allmendinger will not race on Sunday at Las Vegas; instead, Austin Dillon will pilot the No. 51.
