FORECAST & PILOT NOTES · SUPPLEMENTAL

Extended forecast and pilot notes

Current aviation conditions show flight category IFR, wind from 170° at 19 kt, gusting 25 kt, visibility 10 SM, ceiling 600 ft. This report is older than usual, so treat it with caution. Forecast suggests this afternoon rain, high near 41F, low near 39F, 100% chance of precipitation. Key risks: gusty winds; strong winds in the forecast. Note: the NWS forecast for now reads "Rain" but the current METAR shows none of it; the observation and forecast differ, so trust the METAR for current conditions.

PILOT WEATHER NOTES

Gusty windsMETAR
