I feel like I am a broken record here, but again, I live very, very close to Evansdale and I remember the details of this weekend very vividly. For one, it was my son's birthday weekend, and two, my family goes camping every weekend. We stayed local that weekend (at Deerwood) because of my son's birthday party.
Since we go camping, rain tends to cause problems. However, due to the drought this Summer, the rain was welcomed and I was hoping the burn ban would be lifted if we received enough rain.
I believe the official rainfall totals are recorded at the Waterloo Airport. This is on the far Northwest edge of town. I remember it raining early the morning of the 13th, all through the morning. It tended to be a sprinkle/mist from about 5-6am to about 11am. It was enough of a nuisance that a client of mine had a daycare fieldtrip cancelled that morning. The sprinkling started again around 3pm, when I left work that day. This was a very, very short-lived bout, but with unusually large raindrops. After rain in Iowa, the humidity becomes unbearable! I have assumed there were not many people out that day due to the sprinkling rain in the morning, and then the humidity afterwards.
Not that it matters, but it started to sprinkle again the morning of the 14th. I was on my way to the hair salon, worried my hair would be immediately ruined and frizzy for the birthday party. It stopped sprinkling again before I left the salon, only to be replaced by the horrid humidity again.
My opinion only, of course!
