Marquette, MI – Residents along the East Coast and throughout the Midwest could get a “fake fall” preview next week as temperatures are forecast to dip below normal to close out August.
According to the National Weather Service office in Marquette, Michigan, the pattern shift begins Monday, August 26, and is expected to carry through Sunday, September 1. The latest outlook shows favorable probabilities for below-average temperatures stretching from the Great Lakes eastward through New England and southward along much of the Atlantic coast.
Forecasters said the change comes after a brief warmup this week. By late August, cooler Canadian air is projected to settle over the Great Lakes and push into the eastern United States, bringing daytime highs several degrees lower than seasonal averages.
Maps released by the Climate Prediction Center show the strongest likelihood for cooler-than-average conditions centered over the Upper Midwest, including Michigan, Wisconsin, and Minnesota, with below-normal probabilities extending across the Ohio Valley, Mid-Atlantic, and Northeast. Portions of the Southeast, particularly along the Appalachian corridor, may also see cooler readings.
Meanwhile, warmer-than-normal temperatures are forecast to hold across much of the West, including California, Oregon, and Washington, as well as parts of the southern Plains. Florida and the Gulf Coast are also expected to remain above seasonal averages.
The National Weather Service noted that while this “fake fall” signals a temporary autumn-like feel, the region is still several weeks away from consistently cooler weather. The shift, however, may offer a welcome break from summer’s lingering heat and humidity for millions across the eastern half of the country.
