Volunteers not needed for Wednesday morning shift at NFL Experience.

  Although the weather didn't impact too many Super Bowl XLV volunteers on Tuesday, it already has on Wednesday.

A private, mid-morning event for children at the NFL Experience - the NFL Play 60 Kids Day - was cancelled Tuesday night, prompting officials to send emails to first-shift volunteers telling them they weren't needed Wednesday morning.

But only during that time.

The email strongly urged the volunteers - who had previously been assigned to the 10 a.m. to 2:30 p.m. shift on Wednesday - to show up for the 2 to 7 p.m. shifts or the 5:30 to 10:30 p.m. shifts, when the NFL Experience is scheduled to be open to the public.  

Earlier in the day on Tuesday, Amanda Whitelaw, the host committee official coordinating the 10,000-plus Super Bowl volunteers, said they are prepared for the worst, but hoping for the best.

"The weather is just something you have no control over," Whitelaw said. "We control what we can and react to things we can't."
