70+ after first sub 25

Posted: 10 Nov 2020 05:39 AM

Des Moines came up one degree short on Monday of extending a streak of six days at or above 70 degrees for daily high temperature. Having such warm days is doing well considering the very cold conditions just a few weeks back in October with numerous rounds of snow as well. The featured chart presents some metrics on having warm temperatures after the first fall temperature below 25 degrees. The top panel shows the maximum temperature for the period between the aforementioned date and the end of the year. The middle panel shows the maximum temperature against the date of the first sub 25 reading. The bottom panel shows the number of days each year with a high temperature of at least 70 degrees. The 2020 total of six days shown in the bottom panel is doing rather well considering the long term simple average is only one day. It appears unlikely that we will see such warm days again this season, but the year is still 2020 and about anything remains possible including severe storms over southeastern Iowa today.

Good = 14
Bad = 1
