Yesterday was another very hot day in Iowa with high temperatures nearing 100 degrees. It was the fourth day in a row with a high temperature over 90 for Ames. The featured chart presents the yearly maximum daily streak over 90 degrees for high temperature for Ames. Some years, like 2004, the temperature never got that warm for the entire year! Our current streak has a chance of being the longest we have seen in around 20 years.

Thanks for a strong low pressure center to our north pulling warm and humid air into the state on Sunday, temperatures climbed well into the 80s and even topped out at 90 in Des Moines. The featured chart presents the first day of each year that the temperature hit 90 or above. This year tied for second earliest behind 1986. The average first day is not until the first week of June! The bar colors represent if the year was earlier (red) or later (blue) than average. Temperatures today will struggle to reach 60 with cooler weather expected for the rest of the week.
