  • Precipitation amounts during the cold season are not accurate.
  • Newton's (TNU) precipitation counter was resetting at :45 after the hour instead of :55 after the hour during the first half of 2003.
  • Fairfield's (FFL) tipping bucket appears to have been plugged during the
  • Decorah's (DEC) rainfall counter is resetting at :45 after the hour instead of :55 after
