Meteorological fall begins Thursday

We know it's still going to be hot, but those days are numbered as meteorological fall begins Sept. 1. So, what does that mean exactly? Here's the answer.

ST. LOUIS — Meteorological fall is here! But, what does that mean, exactly? And why is there a different "fall" date than the first day of autumn? Record keeping purposes are really the main reason.

Due to the position of Earth, the first day of autumn doesn't always fall on Sept. 22. For that reason, we start "meteorological fall" on Sept. 1 and carry it through Nov. 31.

It was a relatively hot summer throughout the area, with mostly above average temperatures. There were seven days that hit over 100 degrees with 105 degrees as our peak high. Forty-five days hit 90 or above since June 1. 

We’re not far off our yearly average (although that includes a few extra days before and after summer.)

We know we're going to hit 90 again, several more times this weekend. Our average highs start the month of September off in the mid 80s, but finish in the mid 70s. 

Spoiler alert: We should remain above this number for the first couple of weeks. No reason to close the pool just yet.
