I need to visualize the snowfall in the USA for a given time period and city. So you could pick a given day and get a heatmap showing the amount of snowfall at each place in the USA on that day. Monthly or seasonal snowfall isn't granular enough for this application.
Does anyone know where I could get data like this? (Ideally it would already be hooked up to a map so I can explore the data before building the whole thing myself.)
