Mostly on Warm Side

Posted: 09 Aug 2018 05:33 AM

The featured chart shows a weekly progression of trailing 14 day normalized temperature and precipitation departures for Des Moines. The arrows indicate movement from one week to the next with the labelled day showing when the trailing 14 day departure is valid for. The chart is shown for data this year since the end of April. Please recall how cold and snowy it was in April this year. Since that time and only up until recently, temperature departures have been on the warm side of average and precipitation departures have been both wet and dry. Our current weather is trending toward the dry and hot side of this chart, so our brief period below average on temperatures will end with the next update of this plot.

Good = 7
Bad = 0
