Explanation of Climate Graphs

Temperature

The temperature graph depicts the normal, record and observed daily high and low temperature for each day of the year, starting with January on the left, through December on the right.
  • Normal temperature range (difference between the high and low) is shown in light green.
  • Record high temperatures are shaded light red.
  • Record low temperatures are shaded light blue.
  • The dark blue lines depict the actual observed daily high and low temperature range.

Precipitation

The two precipitation graphs depict both the normal and actual observed total precipitation (rain and melted snow) and snowfall, accumulated on a daily basis from the beginning of the year on the left, to the end of the year on the right (or to the current day on the present year's graph).  Total precipitation is the top graph, with snowfall on the bottom.
  • Normal amount of precipitation/snowfall is depicted by a yellow line and light green shading.
  • The stair step line indicates the observed precipitation or snowfall.
    • When the accumulation of observed precipitation/snowfall is above normal, that area is shaded dark green.
    • When the accumulation of observed precipitation/snowfall is below normal, the area is shaded tan.
