October Temp Ranks

Votes: Good: 12   Bad: 0 Abstain: 0

Today's featured map presents IEM computed and unofficial October 2025 average temperature ranks by climate district for the contiguous US. The pattern shown is rather interesting with below average temperatures confined to each coast and warm values found throughout the middle of the country. Persistent upper troposphere flow patterns lead to persistent areas of warmer or cooler than average air masses, which then nicely appear in monthly aggregate stats like today's feature. The start of November looks to be on the warm side of average for Iowa and surrounding states, much like the start of October was.
