A taste of fall could arrive early for parts of the U.S., with cooler-than-normal temperatures expected across the Midwest and Northeast during the final stretch of August, according to recent outlooks from the Climate Prediction Center.

Newsweek contacted the CPC for comment via email on Tuesday.

Why It Matters

While meteorological summer runs until September 1, according to AccuWeather, the CPC's map indicates that several areas could experience below-normal temperatures in the final stretch of August.

What To Know

In a six-to-10-day temperature outlook issued on August 18, which was valid for August 24 to 28, the CPC's map suggested that states with the highest chances of experiencing below-normal temperatures over this period included Michigan, Wisconsin, Ohio, Indiana, Illinois and Iowa.

Parts of northwestern Pennsylvania and northeastern Missouri were also included in this category.

On the other hand, the CPC's map showed that the areas most likely to experience above-normal temperatures during the same period included southern Florida, eastern Washington, eastern Oregon, western Montana and parts of Idaho.

The CPC said its six-to-10-day and eight-to-14-day temperature outlook maps indicated the probability that the observed temperature—defined as the average of daily mean temperatures over the period—would fall into one of three categories: above normal, near normal or below normal.

A daily mean temperature is the 24-hour average of all temperature observations recorded at a given station on a given day. The six-to-10-day and eight-to-14-day averages are then calculated by averaging all the daily mean temperatures within their respective forecast periods, the agency said.

What People Are Saying

Meteorologist Mark Margavage wrote on X on Sunday: "Meteorological Fall Begins on September 1st, but we'll be feeling like fall in the Northeast long before that!"

Meteorologist Bryan Schuerman wrote on X on Monday: "COOLER CHANGES AHEAD: By the weekend, we're going to see the 70s roll in! The Climate Prediction Center's 8-14 Day Temperature Outlook for the end of August and into Early September, brings below average temperatures into play from the Midwest into the Great Lakes & Northeast."

CBS 6 chief meteorologist Steve LaPointe said on X on Wednesday: "Longer term trend shows cooler than average weather returning for a time later this month. This is the latest 8-14 day temperature outlook from the Climate Prediction Center showing probabilities favoring some cooler than average days in the August 20-26th period."
