Will my flight be impacted?
Probability your flight will be impacted based on how far in the future it is scheduled to leave:
| 60 Minutes | Three Hours | Six Hours |
| HIGH | HIGH | HIGH |
Things are scheduled to get worse and not significantly improve in the near future.
Airlines have a tendency to have a “wait and see” approach to weather, so they may delay your flight gambling that the weather will improve enough to fly. In these situations expect to see your departure time shifting further into the future in roughly 30 minute increments.
This situation is the most likely to see flights canceled, and flights are nearly guaranteed to be delayed.
