FORECAST & PILOT NOTES · SUPPLEMENTAL

Extended forecast and pilot notes

Current aviation conditions show flight category VFR, wind from 270° at 6 kt, ceiling 4,200 ft. Forecast suggests this afternoon chance showers and thunderstorms, high near 57F, low near 39F, 74% chance of precipitation. Key risks: high density altitude; thunderstorms in the forecast. Note: the NWS forecast for now reads "Chance Showers And Thunderstorms" but the current METAR shows none of it; the observation and forecast differ, so trust the METAR for current conditions.

PILOT WEATHER NOTES

High density altitudeMETAR

Density altitude about 7,746 ft (field elevation 7,171 ft). Expect reduced climb performance and a longer takeoff roll.

FREQUENTLY ASKED

Does KLAM have a METAR?

Yes. KLAM has a current METAR observation, decoded into plain English on this page.

Does KLAM have a TAF?

When KLAM issues a TAF, its decoded forecast timeline loads live on this page; otherwise use the nearest TAF-issuing field as a planning reference.

What is the field elevation at KLAM?

KLAM sits at 7,171 ft MSL, which factors into the density-altitude estimate on this page.

Is this an official preflight weather briefing for KLAM?

No. wxdecoder.com is for education and situational awareness only. It is not an official weather briefing or a substitute for official sources, NOTAM review, and pilot judgment.
