Big Temperature Drop On The Way (This Fall)

It’s now September and I’m sure some of you are ready for the cooler temperatures and pumpkin-flavored everything!

We ended August with over eight inches of rain (8.07″) making it the eighth wettest August on record in the Quad Cities.

While we still have three more weeks before the official beginning of fall, it’s now “Meteorological Fall”.

Met Fall

That’s what meteorologists call the three months of September, October, and November, the transition between the three warmest months of the year to the three coldest months.

This is also the time of the year when we see the biggest drop in temperatures.  At the beginning, September 1st, the average highs and lows are 82° and 60°.

By the end of November, the average high is 41° and the low is 24°!

Over the next three months, we normally have 8.62″ of rain (and melted snow).  Yes, snow.  In November, we average 1.2″ of snow!

    Thank you for all the hard work you do to explaining meterology.Q:do you think there will be a low to medium la Nina effect this fall/winter season?Also will the PDO or NAO will be significant?-Thanks again,if you’re ever in Galesburg, stop by,Douglas Summers😎🌏🌏🌏


    • Douglas,

      Hello to you and Galesburg! Thanks for the kind words.

      Interesting that you ask about La Nina. It doesn’t look as likely as it did last month, but that doesn’t mean we won’t see it.

      Here’s what NOAA is now saying, “models have slightly backed off their confidence—from 75% to 55-60%—that La Niña will occur this fall and winter. While tropical Pacific waters have cooled, the trade winds have not showed the La-Niña-like strengthening needed to amplify cold-water upwelling. The current outlook favors a weak event.”

      I’m ready for a snowy winter.
