Demanding this hour because of a 71° low-level direction change combined with a 7.8 mph gust spread, a strong-convection indicator, estimated building thermal activity with strength unknown, and a 4.4 mph surface-to-flight speed change. The combined low-level change may produce changing drift and a more demanding control workload.
Gust assessment includes the highest forecast input (10 mph). At least one forecast input indicates strong convection.

What stands out
The strongest forecast concern is a 71° low-level direction change combined with a 7.8 mph gust spread, a strong-convection indicator, estimated building thermal activity with strength unknown, and a 4.4 mph surface-to-flight speed change.
Key takeaways
- The combined low-level change may produce changing drift and a more demanding control workload. Thermal strength is unknown because the activity is estimated.
- Consider a calmer window, especially for newer pilots.
