snow17.py generate a non-zero outflow even when there is no precip or snowmelt. In the screenshot below, cumulative outflow (after all snow has melted) exceeds cumulative precip:
I noticed that when I comment out the w_q term in line 234 (see screenshot below), I no longer see the discrepancy between cumulative outflow and cumulative precip.
Here's a plot of the results after commenting out w_q in line 234:
Commenting out w_q in line 234 appears to have resolved the issue in this particular case, but I don't know if it's a sound solution. Somewhere in the code, it seems there must be an implementation error, because the unedited snow17.py code generates a non-zero outflow in the absence of precip and snowmelt.
