Demanding this hour because of a 4.7 mph gust spread, estimated building thermal activity with strength unknown, and a 5.2 mph surface-to-flight speed change. This speed change may alter drift between launch and the forecast flight layer.
Low forecast confidence: review data limits and model ranges.

What stands out
Three ACTIVE factors combine: a 4.7 mph gust spread, estimated building thermal activity with strength unknown, and a 5.2 mph surface-to-flight speed change.
Key takeaways
- This speed change may alter drift between launch and the forecast flight layer. Thermal strength is unknown because the activity is estimated.
- Consider a calmer window, especially for newer pilots.
