From “false fall” to September scorcher

Many enjoyed the spell of below-average temperatures across the Midwest in late August and early September. The fall-like air is but a memory this week, as late-season heat has made a comeback, reminding us that summer isn’t over yet.

A popular meme about Missouri’s climate sums it up: after the late July and August heat comes a stretch of cooler weather known as “False Fall,” followed by “Second Summer”.

The September scorcher will continue to build this weekend, and likely stick around well into next week. The Climate Prediction Center’s six to 12-day outlook shows above-average temperatures are likely for Northeast Kansas and Northwest Missouri.

As the first day of astronomical fall approaches, many look forward to the vibrant colors that emerge from deciduous trees. To get the most vivid colors of fall to “pop”, we need sunny days, cool nights and moderate rainfall. 

While some degree of color change is guaranteed, stretches of September heat are less than optimal for the best show of fall foliage. Extended hot and dry periods can dull the season’s display, leaving more browns than bright oranges, yellows and reds.

Even in the worst of weather years for fall color, shorter days and inevitably cooler air are sure to bring a few fleeting flashes of color.

Historically, the best time to get a glimpse of fall foliage in the Mid-Missouri River Valley is mid to late October. Depending on the year and species of tree, peak color change can take place a few weeks earlier or later
