High readings in Northern Minnesota

Hi Icebox
Your sensor readings have doubled recently into the Warning range. Is there a change in your environment or in your sensor?

Hi Icebox:
Your station has recently returned to more normal readings. Have you changed the sensor in some way? Your readings were very different between Sept 9 and Oct 16, but similar increases were not seen on other sensors in the area. A post to the forum would help clear this up. I tried to PM you but your user name no longer appears in the valid list.
