✅ Shorten inline switch with multiple passing values

Hi! Would there be a way to shorten this? In python, their pattern matching would have a simple in [x1,x2,x3]

    private static WeatherType WeatherCodeToWeatherType(int weatherCode) {
        return weatherCode switch {
            0 => WeatherType.Clear,
            1 or 2 or 3 => WeatherType.PartlyCloudy,
            45 or 48 => WeatherType.Fog,
            51 or 53 or 55 => WeatherType.Drizzle,
            61 or 63 or 65 or 66 or 67 or 80 or 81 or 82 => WeatherType.Rain,
            71 or 73 or 75 or 77 or 85 or 86 => WeatherType.Snowfall,
            95 or 96 or 99 => WeatherType.Thunderstorm,

Most you could do is, probably

return weatherCode switch {
    0 => WeatherType.Clear,
    var w when new[]{1, 2, 3}.Contains(w) => WeatherType.PartlyCloudy,
    // ...
}

return weatherCode switch {
    0 => WeatherType.Clear,
    var w when new[]{1, 2, 3}.Contains(w) => WeatherType.PartlyCloudy,
    // ...
}

But that hardly shortens the code
