It was the 4th wettest May on record

Ames, Iowa – May rainfall ended up just a little short of being double the normal average.

State Climatologist Justin Glissen says we got trapped in a pattern that wouldn’t go away.


He says average rainfall for May is 4.5 inches.   The month ended up just a little cooler on average.


He says with all the cloudy days, the three-degree difference from the average was a little surprising.


Glisan says the climatological outlook early on for  June showed an equal chance for both higher or lower than normal rainfall and temperatures. He says the mid-May outlook showed a little warmer and less rainfall in the outlook.


The wetter than average June comes after March and April were both slightly below average in precipitation.
