Each colour starts at the value shown. Wind colours match across all three units. Dry cells stay neutral. Colours describe the displayed values, not official weather warnings.

Coordinates: 36.9891351°N, 138.8224874°E · Requested elevation: 258 m. Model terrain: 640 m. Terrain and 1000/925/850/700 hPa profiles are used for height estimates.
Outside the available profile, temperature uses an estimated 5.5°C/km height correction; wind retains the nearest available model-level value. Humidity is estimated with adjusted pressure and temperature.
These are altitude estimates, not a simulation of local mountain terrain. Precipitation, cloud and sea-level pressure use horizontal interpolation only.
Precipitation includes rain and snow water equivalent: preceding 3 hours through day 6, then 6 hours (see cell tooltip). Snow (cm) estimates fresh snowfall from precipitation and temperature using the GFS conversion; it is not snow depth on the ground. Freezing (m) estimates the lowest resolved 0°C crossing above sea level. When all sampled levels are warm, the upper profile limit is shown (see tooltip). < marks an entirely cold sampled profile and its lower height limit. No extrapolation is used.
