I have a love-hate relationship with thunderstorms. As a Dispatcher, thunderstorms bring what I feel is the biggest challenge to the job. It is also a Dispatcher’s time to shine and when their pay check is truly earned, making the job fun, rewarding and incredibly satisfying.

The level of challenge sometimes surprises many people because thunderstorms have a relatively short life. Snowstorms present some challenges, but when a blizzard is present, if conditions are that bad, the airport will often shut down in advance or the airline will have canceled enough flights to where the dispatch workload is lighter. Snowstorms are easier to predict and sit over an airfield for a long period of time, so when you can’t get in, you know you’re done for a while. Thunderstorms, on the other hand, tend to pass through a location in about 20-30 minutes. Though fast-moving (average from 25-40mph, or faster!) there are multiple influences that affect the growth, dissipation and speed of the storm, making predicting the time of the storms arrival very challenging. Not to mention that storm cells may be in clusters, where an airport can receive a torrential downpour, while a neighboring town a few miles away can be dry as a bone. Try forecasting that 8 hours out!
