As always, when there is wind I struggle to get a good measurement. I'm going with 4.5".
It appears the wind destroyed the ratio(the blowing snow really compacts). Despite the wind, my gauge still caught 0.53", which suggests even more than that fell. However, even the 3.1" on my snow board melted down to 0.48", a terrible 6.5 to 1 ratio. I know we got more than 3.1". The reports from in and around Cedar Rapids range from about 4.5 to 6", so I'm going with the low end of that. I always end up with the low end of the range where there is wind.
Much of the Des Moines warning area crapped out, only receiving 0-2". The MN/IA border area was the winner.
