Snow melt calculations

I am unsure if this is the correct way to calculate snow melt. Rather should only negative changes in snow depth be summed? I'm thinking of the situation where a single event includes both melting snow and new snow.

storms$snwd_diff[i] <- sum(weather_temp$snwd_diff)*0.0393701 # convert from mm to inches
