Something like this would be good I think, and easy enough to add.
const snowfall = require('@erikwatson/snowfall')
snowfall({
count: 250, // The "base" number of snowflakes, as the true total is calculated
bgColor: '#cccccc', // the colour of the snowflakes in the background
fgColor: '#e3e3e3', // the colour of the snowflakes in the foreground
wind: 1, // Negative is left blowing, Positive is right blowing
minSize: 2, // the smallest snowflake radius
maxSize: 6 // the largest snowflake radius
})
