85+ in September
Posted: 20 Sep 2017 05:32 AM
Temperatures were warm on Tuesday along with some rather muggy conditions for this
time of the year. The high temperature for Des Moines reached 85 degrees after a morning
low of 62. The featured chart looks at the hourly temperature distributions on days in
September with the high temperature at least 85 degrees for the site. The boxes represent
the 25th and 75th percentile and the whiskers are the 5th and 95th. It is kind of interesting
to note the tight temperature ranges overnight on these days. Having temperatures in the
60s to start off the day are the most common. In some cases, we can warm out of starts in
the upper 40s, but it is rare. The forecast looks to continue today's trend of 60s for lows and
80s for highs as it will feel like summer for a bit longer.
