1 Rain season: Jan 1st to Dec 31st.   2 Snow season July 1st to June 30th.   3 Updated at 7:00 AM Daily..   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 Source: New York State Department of Environmental Conservation.   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.
