Weather Report informs you of changed weather.
If "useSnowDuration" is true, it rains when it's not in specific duration(using "ChanceToRain_duration"), snows in the duration(using "ChanceToSnow_duration").
If false, both chance to rain and chance to snow applied as is, and chance to sunny is a value of 1 minus these two values.
Requires SMAPI, not uses Harmony patch.

for legacy only:
If "useSnowDuration" is false, the lower chance is taken from the higher of the two. ex) if rain chance is 0.3, snow chance is 0.2, then actual rain chance is 0.1.
