Yearly profiles

Posted: 13 Sep 2012 05:40 AM

Yesterday's feature compared 2012 total number of days above a given high temperature threshold for Des Moines with the maximum for any year. Today's feature is a slight modification showing the number of days above a given threshold for every year for the period up till 11 September. For temperatures above 100, 1934 and 1936 stand apart from any other year. But for lower temperature thresholds, this year shows a remarkable departure from other years. Much of this was thanks to one of the most extremely warm months on record, March 2012. The forecast for the next week has our weather turning much more fall like and very comfortable!

Good = 38
