So far this month, the National Weather Service has recorded 3.88 inches of precipitation. That's only good for the 8th wettest May on record if we use the Salt Lake City International Airport record for the past several decades and other nearby observing sites to go back to the late 1800s.

I think the key psyche points are 4" just because it's a nice round number and 4.27" as that would get us into the top 5 all time. Given the hit and miss nature of these storms, I make no specific predictions, but climbing up the list is certainly possible and if we can get a big dump right at the airport, perhaps we'll do even better.
