Compaction definitely plays a role, especially in long duration storms like this one. Plus with the marginal ground temperatures, the snow struggled to accumulate on the concrete until mid afternoon on Wednesday. Some people definitely drift measure or over-inflate their totals for sure, but there are definitely a lot of people that’ll just stick the ruler on the ground after the storm and call it good. For me, I have a snowboard that is placed as well as I can place it and go out and measure every 6 hours (00z, 06z, 12z, and 18z). I make sure it doesn’t get drifted into or anything, and clear it every 6 hours as well. I have one of those official snow measuring rulers and get down low when measuring so I’m staring at the lines straight on. The Tuesday night into Wednesday morning portion seemed to overperform imby, as I measured 2.0”, while areas farther north definitely didn’t get that much. It also basically didn’t accumulate on the concrete except for shaded areas. The afternoon round only brought 4.1” to mby, and I think some of the better banding avoided Macomb County. I can confidently say I measured 6.1” from the event, and then a random 0.1” Thursday morning. I was a student volunteer at DTX in 2016 and I’ve gone through multiple rounds of spotter training, so I know the importance of accurate reports and strive to not low-ball or high-ball amounts. Snow measuring is definitely tricky at times and some people treat it as a competition, so I get how that can be really frustrating.
