The decision to cancel a show due to bad weather needs to be well-informed. Fortunately, there are a lot of resources available. Websites like livewxradar.com offer real-time moving Doppler radar images that can drill down to a matter of meters to show where storms are and in which directions and how quickly they’re moving. One thing I’d strongly recommend doing is not only consulting those sites but also taking screen shots of them as well. The Live Weather Radar site is time-stamped in both ET and GMT and can provide a record, not only of the weather at a particular moment in time, but also of the fact that you consulted it, because, given the amounts of money involved, even a decision not to go on can lead to litigation.
