Five 50s So Far

Posted: 15 Feb 2017 05:35 AM

The Des Moines Airport was able to reach 50 degrees for the fifth time this February. The featured chart presents the number of 50+ degree days for this same 1-14 Feb period each year. The top panel shows the number of days each year with the bottom panel showing the distribution. The total of five days is around the 10% frequency, so roughly one in ten years. The largest number of such days was 15 back in 1954. Accumulating 11 more days this month to break the record is not impossible giving the current very warm forecast.
