FORECAST & PILOT NOTES · SUPPLEMENTAL

Extended forecast and pilot notes

Current aviation conditions show flight category VFR, wind from 170° at 9 kt, gusting 16 kt, visibility 10 SM, ceiling none. Forecast suggests tonight mostly cloudy, low near 25F, 2% chance of precipitation. Key risks: high density altitude.

PILOT WEATHER NOTES

High density altitudeMETAR

Density altitude about 5,259 ft (field elevation 5,550 ft). Expect reduced climb performance and a longer takeoff roll.
