Your screenshot don't tell what you want, or I missed something.
I guess you want a meteogram, or at least a line, with precipitation types. Am I right?
Precipitation types are partly shown, with snow, mix of snow and rain, rain by icons.
Canon snow being artificial snow made by snow canons, do you want that Windy provide data showing when snow cannons can work?
Conditions with low air temperature (wet bulb temperature more exactly), humidity and low wind are needed.
