CHICAGO (AP) – Unseasonably cool temperatures will arrive next week in the Midwest and as far south as Arkansas and Oklahoma. It is not, however, the second coming of a polar vortex, something the National Weather Service says it regrets tweeting earlier this week.

Weather Underground meteorology director Jeff Masters says the weather pattern is similar to those dreaded words, but the key difference is that the chilly air mass isn’t coming directly from the arctic.

Masters says that Typhoon Neoguri in Japan altered the path of the jet stream and allowed polar air to spill out of Canada. That means next week’s temperatures will be as much as 15 degrees cooler than normal in the Midwest and could reach 90 in the normally temperate Pacific Northwest.
