About Author

Jeff Wilcox serves as the Senior Forecaster at the Iowa Weather Network with primary focuses in long term weather operations and climatology. Weather has always fascinated me since I was young. My first memory of weather was back in 1988 during the Mother’s Day Tornado Outbreak in 1988. I can vaguely remember the cold snap the state experienced around Christmas Time in 1983, but was too young to remember that vividly. Growing up in Anamosa since moving there in 1981, I’ve experienced all the weather imaginable from bitter cold in early 1996 to hot and humid weather in 1995 and again in 2012, to floods in 1993, 1999, 2008 and 2013, Droughts in 1988 and 2012. After doing some other website work and other interests which included publishing a novel in 2007, I finally began the Iowa Weather Blog on June 27th 2008, right after the Flood of 2008. I worked it alone for hours on end giving out weather information that I thought was appropriate for those that wanted to know what was going on in their skies and what was to come. I continue to work on the blog along with the Iowa Weather Network which was created back in 2012 and continue to do so to this day.
