Weather Flashback

October 2021 - September Summertime (September 3, 2021)

Summary

This summertime scene from Norman captures the warmth and dryness that would end up characterizing the month. Daytime highs in the 90s (or even 100s) are not uncommon in Norman in September; however, the 20 days with highs at or above 90 °F stand out as rather unusual for the month. Precipitation was similarly unusual with only about a half-inch of rainfall for the entire month versus the 3-4 inches that usually falls. Synoptically, the unusual warmth and dryness was caused by persistent high-pressure aloft.
