Will Summer Heat Return After September 14?

Temperatures across central regions are expected to drop by nearly 20 degrees in a matter of days, shifting seasonal patterns as average autumn thresholds approach, according to the Columbia Missourian.

Climatological data indicates that the average last 90-degree day falls on Sept. 14, making sustained high temperatures increasingly unlikely as the calendar advances, the Columbia Missourian reported.

The forecasted cooldown marks a distinct transition away from summer-like heat into more typical September conditions. Meteorological tracking highlights that sustained triple-digit or high 90s readings become statistically scarce after mid-September.

Regional forecasts from the Columbia Missourian point to a swift descent in daily maximums, altering local outdoor activities and energy demand profiles as autumn weather takes hold.
