Fitting for it being "Friday the 13th", a very large website change has been implemented. This update was driven by the need to migrate from Bootstrap version 3 to version 5. This required updates to most every app on this website. So please let us know of any issues or poorly rendered pages.

Daily Feature
Hours of 65+°F Dew Points

Votes: Good: 9

It has certainly started to feel more like summer this week with the warmest temperatures so far this year and an increase in humidity with dew point readings reaching the upper 60s degrees Fahrenheit. Such humid conditions have been somewhat infrequent so far this growing season. The featured chart looks into the number of hourly observations from the Des Moines airport with a dew point of at least 65°F between 1 May and 12 June. The top panel displays the yearly number of hours and the bottom panel shows the hour of day simple climatology count and 2025's total. This year's total barely eclipses the next previously lowest value during 2009. The plot shows plenty of year to year variability and the low total this year doesn't even crack the top 10 lowest plotted over the period of record for the site. The humidity does look to stick around into next week and help support a number of chances of needed rainfall.
