Key Takeaways:
Wildfire smoke, primarily from Canadian fires, is causing hazardous air quality and poor visibility across the Midwest and Northeast, severely impacting EAA AirVenture Oshkosh.
Arrivals to AirVenture are expected to be delayed due to widespread MVFR to IFR conditions caused by the smoke plume.
Pilots face significant challenges, including reduced visibility, unreliable automated weather reports, difficulty judging distances, and unpredictable conditions that may make VFR flight impossible.
The air quality map from AccuWeather shows a smoke plume from Canada, which is experiencing a record number of wildfires, reaching the Midwest and stretching to the Northeast. Conditions range from moderate and poor to unhealthy and dangerous.
