From what I recall, Forecastie already does this. The "rainfall" should be named "precipitation" and shows either snow or rain, whichever is forecast to fall.
There are a few issues with that. First, as far as I know the app only shows rainfall in a graph format and the scale is completely ambiguous. How much time does each bar represent? Do I have to add the bars together to get the total or is it accumulative?
Also, snowfall is always much more than rain for a given amount of precipitation. The general rule of thumb is that a storm that would have produced 1" of rainfall will instead produce ~10" of snowfall. This conversion is simple if you are looking at a pure snowstorm, but often they start or end as rain or sleet making the conversion more complicated. Weather forecasters take all of that into account when projecting snowfall from a given storm.

i presume you mean the x-axis? all forecasts in the app are shown at 3 hour intervals.
also, the blocks are labelled with the day, so they're not entirely ambiguous

that makes sense, but doesn't change my answer. the graph will show whichever type of precipitation is predicted on the same scale. the app also provides text descriptions of the forecast weather, on the "main" screen

i don't have much experience of snow, this sounds reasonable though. i'm not sure how to respond, the API docs on the OWM site will have more info
https://openweathermap.org/forecast5
look for the item named forecast.precipitation
all forecasts in the app are shown at 3 hour intervals.
This is very helpful, thanks!

I have seen that, but it is unclear how far into the future that figure is projecting. But with the info above, I should be able to figure it out.
Thanks!
5 days, at 3 hours. all forecasts in the app are that length, it's what the FLOSS subscription provides.
I'm not sure if this is possible with the OWM API, but it would be useful to get projected snowfall either by day or for the next 24 hours.
