Climate data on this page is PRELIMINARY (unofficial). CERTIFIED (official) climate data is available from the National Climatic Data Center (NCDC).
Monthly plots for each station can be viewed by clicking on the station name below.
For the yearly plots shown above, observed temperatures are shown by the dark blue areas, normals with the light green areas, record highs in the light red areas, and record lows in the light blue areas. The bottom portion of the graph indicates the precipitation for the year to date. The yellow line (and green area below it) represents the normal year to date total at the given time frame. Periods that have year to date totals above the climatological normals are shown by dark green areas above the yellow line. Periods that are below normal are shown with the brown areas below the yellow line.
Below is an example of the monthly climate plot. The observed high and low temperatures are indicated by the tops and bottoms of the vertical dark blue bars, respectively. The normal temperature ranges are indicated by the green band. Record highs are shown on the top of the light pink band, and record lows are indicated along the bottom of the light blue band.
