Temperatures Shifting Nationwide in Late August

A changing weather pattern on the horizon for the US is bringing falling temperatures in the Midwest, while above-average temperatures will be sticking around on the East Coast and the West Coast.

As we go into next week, the jet stream that is normally situated over Canada will be dipping down over the Northern Plains and causing temperatures there, as well as in the Midwest, to fall as much as ten to fifteen degrees.

Late August Shift

West Coast

Thanks to the jet stream’s movements, though, a ridge of high pressure will build over the West Coast. As the hot air is cooled and blown away from the center of the country, the coast will see temperatures rise to above-average levels for the back end of August going into early September.

Expect highs of 106 in Las Vegas over the weekend, along with temperatures in the high 70’s to low 80’s in the Pacific Northwest.

Midwest

The Midwest will see a notable drop in temperatures over the weekend as the jet stream cools the region down and displaces lots of hot air. Expect to see temperatures like 77 in Kansas City, Chicago, and Omaha throughout the weekend. Even as far south as Little Rock and New Orleans, we expect to see temperatures falling to below-average ranges for late August.

East Coast

In a similar story to the high-pressure ridge that will develop over the West Coast, the East Coast is expected to see a similar ridge of high pressure. This means we can expect above-average temperatures across the weekend in the Southeast and East Coast.

However, the Southeast will likely also experience a number of thunderstorms, offering lots of cloud cover and precipitation. This could result in lower overall temperatures on the ground.

September

Another cold front will be hitting the Midwest early next week, likely setting up the beginning of September as a cold few weeks in the region. The Northern Plains and Great Lakes are likely to continue seeing below-average temperatures due to the jet stream’s movements.

This also means we can expect above-average temperatures to stick around on the coasts, as the high-pressure ridges there will have similar conditions should the cold fronts stay consistent.
