FORECAST & PILOT NOTES · SUPPLEMENTAL

Extended forecast and pilot notes

Current aviation conditions show flight category VFR, wind from 280° at 9 kt, gusting 16 kt, visibility 10 SM, ceiling none. Forecast suggests tonight slight chance rain showers then mostly cloudy, low near 70F, 15% chance of precipitation. Key risks: high density altitude; thunderstorms in the forecast. Note: the NWS forecast for now reads "Slight Chance Rain Showers" 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 7,975 ft (field elevation 5,055 ft). Expect reduced climb performance and a longer takeoff roll.

FREQUENTLY ASKED
Does KLMO have a METAR?
Yes. KLMO has a current METAR observation, decoded into plain English on this page.
Does KLMO have a TAF?
When KLMO 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 KLMO?
KLMO sits at 5,055 ft MSL, which factors into the density-altitude estimate on this page.
Is this an official preflight weather briefing for KLMO?
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.
