Historical odds for a SPECIFIC trip window at one resort — 'Whistler on March 27', 'Vail Jan 10–17'. From ~30 years of ERA5 monthly history it blends the window's months (weighted by days) into: the snow-day probability (the headline — for a short window how OFTEN it snows beats how MUCH falls in a season), window-scaled expected snowfall and typical base depth, the same window across the last 5 individual seasons, and the best nearby month (±1) by snow-day odds. Window max 31 days; dates are YYYY-MM-DD. This is HISTORY, not a forecast and not a prediction — for the next 14 days use get_weather_forecast, and for a whole-month question use get_monthly_snow. Windows with under 5 tracked seasons return insufficient rather than thin odds.
