1 Rain season: Jan 1st to Dec 31st.    2 Snow season July 1st to June 30th.    3 Snow manually measured usually around 7AM and 7PM.    5 Estimated amount of water needed to replace the water used by plants and evaporation from the past week. (Negative numbers mean amount of water needed, positive numbers mean excess water is present.) 6 Air Quality Index is provided by Minnesota Polution Control Agency and is updated hourly between the hours of 6AM and Midnight. 9 Solar Index represents either an absolute scale of solar energy (W/m²) using the station’s recorded maximum or a percentage of computed theoretical solar maximum using the station’s location and time of day. These indices differ most when the sun is low on the horizon. The current scale is shown, and will toggle if it or the icon is clicked.
