IEM Daily Feature

Keeping the streak going

Posted: 30 Oct 2026 05:30 AM, Views: 474
The pleasant-for-late-October weather continued on Thursday with highs in the 60s and even low 70s for Iowa. For places like Des Moines, it was the 12th straight day with a high temperature above average. The featured map looks into the current daily high temperature streaks above (red positive numbers) or below (blue negative numbers) average based on the first order NWS CLImate reporting sites. Today's (30 October) high temperatures will struggle to keep the streaks going at a number of locations, but warmer weather is expected again on Saturday and lasting well into next week. Significant cool/cold weather continues to be absent so far this fall season!
