Way below March 2012

Wednesday was yet another rather warm day this March with highs well into the 70s and even a few 80s. A few folks have wondered how this March compares with the benchmark warm March of 2012. The featured chart presents the month to date accumulated average temperature computed over the state of Iowa by the IEM. The black line is 2012, the red line is 2026 and then the spaghetti lines after the 25th represent scenarios appending previous 26-31 March values onto this year's accumulated value to represent a range of possible scenarios. As you can see, even the warmest scenario still comes up about 6 to 7°F (hi kids) degrees short of 2012. It is interesting to see how 2026 did have a lead over 2012 up until the Ides of March, but the second half of March 2012 was exceptionally warm.
