LOL! I think I have the same pic. If the kid has his left arm in a sling, that would be me. I had a bad accident with a picket fence while roller skating and it took over 150 stitches to close the wound.
The weather center may have recorded a trace in 1958, but I distinctly remember 4 inches on our picnic table. And the pics I have of 1949 (attached) look like 6 inches or more on the ground. In fact, my mother's note says 5-6 inches. Also, she dates the snowfall as Jan 31 - Feb 1, not Jan 30.
