Choose a winter and compare observed snow against the long-run November-April climatology.
Observed snow depth is shown for lower and upper slopes, with temperature as context. The long-run reference comes from the historical weekly climate model and is deliberately kept separate from individual reporting seasons.
How the selected winter compares with the historical baseline.
The comparison uses only matching winter weeks, so an incomplete season is not treated as a full winter.
Altitude dependence, retention and temperature context.
Upper and lower-slope depth are interpreted together; the gap between them indicates how strongly snow cover depends on elevation.
Coverage and stability of the historical comparison.
This is an observational snow-depth archive, not a snowfall climatology. Confidence reflects reporting coverage and the number of comparable seasons.
Weekly snow depth and temperature through the selected winter.
Compare lower and upper-slope snowpack development through the active part of the season.
The preceding winter as a direct reference season.
Use this card to see whether the selected season accumulated and retained snow earlier or later than the winter before it.
Typical weekly mountain/valley depth and temperature from the long-run climate series.
This chart uses the indexed historical climatology behind Snow reliability. It is stable planning context, not an average of the currently selected reporting seasons and not a forecast.
What the historical profile says about snow reliability.
The archive is interpreted by timing, depth, lower-versus-upper spread and late-winter retention.
Upper-slope snow depth across the five most recent available winters.
The same week positions are aligned across winters, making year-to-year variability visible without duplicating week labels.
How much recent winters differ from each other.
Season means are calculated from comparable upper-slope weeks so missing observations do not automatically make a winter look weak.
