FORECAST: Severe storms, heavy rainfall possible
The cancellations and delays are due to the incoming storms and the ripple effects of the fire last week at an Aurora FAA facility, according to the aviation department.
Thunderstorms, including heavy rainfall and damaging winds, are expected to move into the area Thursday evening, according to the National Weather Service.
Some areas may see more than inch of rain by Friday morning, and high winds and hail are also possible, according to the weather service.
