July Climate Summary

July Precipitation Highlights:

As is typical during mid-summer, rainfall was hit and miss over much of the area. Well below normal rainfall was reported over most of central Illinois, where some locations were 2-3" below normal. Springfield recorded only 0.52" of rain, which set their 5th driest July (since 1879). The lack of widespread rainfall resulted in "abnormally dry" conditions developing over much of the area by late month, according to the U.S. Drought Monitor. More frequent rainfall over far southeast Illinois produced above normal totals, southeast of a Flora to Casey line.

July Temperature Highlights:

Temperatures were well above normal across the area in July. Monthly averages of 2 to 3 degrees above normal were common. A stretch of hot and humid weather from the 18th-20th saw highs reach the mid 90s, with dew points in the mid 70s to around 80 degrees. This produced peak heat indices of 110-115 degrees. Record warm lows in the upper 70s were set over parts of central Illinois on the 19th.
