Demanding this hour because of a 128° low-level direction change combined with a strong-convection indicator, a 3.2 mph gust spread, and estimated building thermal activity with strength unknown. The combined low-level change may produce changing drift and a more demanding control workload.
At least one forecast input indicates strong convection.

What stands out
The strongest forecast concern is a 128° low-level direction change combined with a strong-convection indicator, a 3.2 mph gust spread, and estimated building thermal activity with strength unknown.
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.
