The heat is on the way back to the Mississippi and Illinois Valleys for a few days before rain arrives this weekend and cools us back to typical late August temperatures.
After highs in the mid-to-upper-80s Wednesday, we could reach or top the 90° mark Thursday, Friday, and Saturday.
So far in 2012, we’ve already been 90° or warmer a total of 37 times. That is the most we’ve experienced since we had 34 of them in 2007. That August we hit 90° or higher twelve times. Earlier this month, we had five days at that level.
Temperatures this August, with all the pleasant days and cool nights, are running 3.3° below average.
After the midweek to early weekend warmth, high temperatures start falling back into the low-to-mid-80s Sunday through next Tuesday.
As September draws closer, a look back at the past five years shows that we had two days in September 2011, 2010, and 2008 with highs of 90° or higher.
In September 2009, there were no 90° days. However, in September 2007, we had eight days when the highs hit 90° or warmer.
And, while we have not had any 90° days in October from 2007-2011, on October 3, 2006, we hit the record October high in the Quad Cities of 95°.
While it’ll be warmer than average through Saturday and then cool back some by early next week, more warmth is on the way. Here’s the Climate Prediction Center temperature forecast that takes us through Tuesday, September 4, 2012.
So, don’t pull out the sweatshirts and put away the air conditioners just yet.
