i'm around same. maybe a tad more. I'm not going to account for compaction. will just use the old stick ruler in ground. and round up if i'm between numbers
90% sleet. 5.5"
NAM did good with the warm nose. 13z. The other models didn't catch on until later or not at all. There were a couple runs with an 11z warm but it still was a legit red flag. it was awful on everything else
if you don't have a ruler, a credit card is 3.4" measure and use this site. hopefully this will be moot in about 45 minutes
