Past IEM Features tagged: summer09
Just about any way you slice it, the summer of 2009 has been exceptionally cool. The featured graphic tallies the number of days between 1 May and 9 Sep that had a high temperature below 80 degrees. With unofficial data, the total for 2009 dwarfs the next highest value and nearly doubles the average value. The next two highest years and lowest two years are shown for comparison. Cedar Rapids has a chance to hit 80 today!
Preliminary data suggests that Cedar Rapids has only seen 26 days with a high temperature above average since 1 May and that would be a record minimum for the time period up until 25 August. The next two lowest and two highest years are shown on the featured chart. 1988 was a very hot and dry year in Iowa with just a mere 17 days below average. The forecast for today places us around 80, but thunderstorms will prevent significant warm ups.
Since the first of May, the warmest temperature recorded in Ames was 86 degrees back in mid May. This ranks as the third lowest high temperature for the period as compared with all other years back to 1893. It is disconcerting to see the years 1993 and 2008 (flood years) show up on this plot as well. There is some hope in the forecast for warmer weather with highs back in the 80s by Wednesday.
