Chaque couleur commence à la valeur indiquée. Les couleurs du vent correspondent dans les trois unités. Les cases sans précipitations restent neutres. Les couleurs décrivent les valeurs affichées et ne sont pas des alertes officielles.
Préparation des graphiques…
Les heures et valeurs correspondent aux prévisions détaillées. Touchez une valeur pour plus de détails et faites défiler horizontalement pour les jours suivants. Les précipitations représentent l’équivalent en eau total par intervalle, neige comprise. La neige fraîche correspond à chaque intervalle, et non à l’épaisseur au sol.
Comparaison GFS et ECMWF. Chaque modèle conserve ses heures et son horizon de prévision. Les quantités de précipitations et de neige couvrent leurs propres intervalles, qui peuvent différer entre modèles.

Coordinates: 45.1643259°N, -84.9324011°E · Requested elevation: 218 m. Model terrain: 283 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) uses additional 600/500 hPa temperatures when available and 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.

Boyne Mountain is a downhill ski area in Michigan, United States. Mapped terrain includes beginner, easy, intermediate, advanced routes. Its mapped lift network extends from approximately 218 to 352 metres above sea level. Cross-country skiing is also mapped within the area.

Forecast table times: UTC.
Coordinates: 45.1615545°N, -84.9393051°E · Requested elevation: 352 m. Model terrain: 282 m. Terrain and 1000/925/850/700 hPa profiles are used for height estimates.
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) uses additional 600/500 hPa temperatures when available and 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.
