For specific daily observations, visit http://www.weather.gov/climate/index.php?wfo=ilx and select the "Preliminary Climatological Data (CF6)" option. 


 Here are descriptions on how to interpret these graphs:

Climate plot for Lincoln for July 2013

This is an example of the monthly climate plot.  The observed high and low temperatures are indicated by the tops and bottoms of the vertical 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.

Please note that while all sites (except Bloomington Airport) have the normals indicated on the plots, only the data for Lincoln, Peoria, and Springfield will have record data included. 

Lincoln climate data for 2013

This is an example of the year to date climate plot.  As with the monthly plot, 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 and snowfall 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.

As with the monthly graphs, the records are only available on the graphs for Lincoln, Peoria, and Springfield.
