Peoria, Ill. – Through the 29th, the month of July has been a warm and dry month for much of Illinois. The worst of the heat came between July 17th and July 21st when high temperatures peaked between 89° and 95° with heat index values near 110°.
Since then, there have been a few hot and muggy days but temperatures have generally been near average with high temperatures in the mid-80s. As we round out the end of July, it looks like cooler weather will be moving in and will stick around through the first few weeks of August.
As previously mentioned, it has been a warm July. According to data from the Midwestern Regional Climate Center (MRCC), temperatures have been about 2-3 degrees above average across Central Illinois throughout the month. Peoria’s average temperature through July 29th is 78.8° which is tied as the 18th warmest since 1883.
It has also been a dry month for the region with much of the area sitting at 1-3 inches below average in precipitation for the month. Despite all the rain that had fallen earlier in the year, the latest Drought Monitor now considers portions of Central Illinois to be “abnormally dry” which is low-end drought conditions.
Cooler weather is settling into Central Illinois this week with high temperatures expected to sit in the lower to mid-80s through Friday with dry conditions. While temperatures are expected to warm up for the weekend, the 6-10 Day Outlook from the Climate Prediction Center shows that cooler and wetter conditions will return next week. This pattern may persist through the first half of August.
