Rain, rain go away. As Paul Douglas said in his Star Tribune column, "welcome to the land of Lakes, Ponds & Puddles".
If you're of the mind that it seems much wetter than normal, you're right on the money. It is wet, it has been wet, and we're setting records all over the state.
There is some data that points to these wetter years becoming more common as an effect of climate change. The Minnesota Pollution Control Agency says that we should expect as least a "slight increase in projected annual preciptation across the state". On average, they say summers will be warmer and drier while winters will be snowier (or wetter).
