arcgis desktop - Sum attribute in overlapping polygons


I have a month's worth of snowfall contoured polygons in one feature class. Polygons represent one day and has a field called SNOWFALL. How can I display the total snowfall for the month? I have the standard license.


I have attached a screenshot of the identity tool on a polygon.


I tried a union, then after that a dissolve by Shape area with Sum of Snowfall checked. However many polygons have the same area so that didn't work.
