All things considered the weather around the central Midwest was pretty choice Wednesday as highs in many areas were back in the 80s. The month though has been a roller coaster with a high in Cedar Rapids of 91 the 6th followed by a 52 the 9th. Season change!

After a dry first week the 6th through the 12th was a wet period with some later reports (beyond the graphic) showing as much as 9 inches of rain in and around the Quad Cities. A real drought...

Before we get into the weather, I'm going to let you in on a special project I've been working on. I'm writing a brand new book on the August 10th Derecho which historically, could very well be the worst storm in Iowa Weather history. One of the key elements in telling the story will be pictures. I need good ones from all around Iowa. Not only can you help me, you can get your name, image, and community in the upcoming book.

With 7 tropical systems in the Atlantic being monitored, and only 3 names left reserved for the Atlantic Hurricane season, we are likely going to run out of predefined storm names to use.

The only time this has been done was during the historic 2005 hur...

Localized spots have had as much as 7-8 inches. These are the 7 day rainfall estimates. These only go through Thursday morning so significantly more has fallen and is not incorporated in the graphic.

The 7 day...

Just Looking at the 500mb jet stream pattern you would be hard pressed to think that some parts of eastern Iowa have had over 6 inches of rain the past few days (some estimates as high as 8"). There's ridging over much of the eastern U.S. with the majority of the upper air energy contained within a closed low centered over Colorado. At face value, not that exciting in my area..

However, the satellite tells a far different story. Around that circul...
