Still time for more 90s

Posted: 28 Aug 2012 05:33 AM

Warm and rather muggy weather has returned to Iowa with highs around 90 degrees. The forecast calls for more of this weather for this week to end August. Will the end of August bring the end of 90 degree weather for Des Moines? The featured chart presents the last day each year whereby the high temperature was at or above 90. The black line represents the average last date, which is still in our future this year! The bottom chart is a simple comparison between the last 90 degree date and the average temperature for that year. The really warm years do not necessarily have a late last 90 degree day. With this year set to smash the average temperature record, we will not necessarily see 90 degree weather into October.

Voting:
Good = 30
Bad = 7
