Weather Today: Polar Vortex Returns This July; See Map of US States Affected

And you thought the polar vortex was over and done with.

Months after one of the chilliest weathers in recent history, forecasters are now warning that it will get colder than usual (or less hot) at this time of the year, which is supposed to be the peak of summer in the Midwest and Central U.S., as noted by Mashable. Which also makes the phenomenon's timing odd.

"The region that was locked in the deep freeze for the entire winter and much of the spring - Lake Superior's ice cover lasted until June, setting a new record - is about to shiver again," the site said. "OK, maybe not shiver. But it's going to be 20 to 30 degrees cooler than average for this time of year."

Although the timing is indeed bizarre, the positive consequence of this unusual climate change is that the cold won't be felt as much.

"Forecasters say polar air from the Arctic Ocean is expected to arrive in Canada and the United States next week, bringing unseasonably cool temperatures to the eastern half of the country," Yahoo! News explained. "Temperatures in Chicago will top out in the low 70s by midweek, making it seem like mid-September rather than mid-July. Compare Wednesday's forecasted high - 72 degrees - with the temperature on July 16, 2013: 93 degrees."

Texans can also expect "comfortable" temperature levels due to the backward trajectory of air, as how the National Oceanic and Atmospheric Association described it.

"Temperatures could fall to about 20 degrees below normal in Kansas and Oklahoma," Yahoo! News continued, quoting information from the National Weather Service.

"On the west side of the Rockies, tropical Pacific air gets funneled northward from around Hawaii toward Alaska while California dries out and roasts; on the other side, cold air from the Yukon cascades southward toward the Midwest and East Coast," reported Slate's Eric Holthaus, the site's resident meteorologist.

Some may not be pleased with the dip in summer temperatures, like Jerry Shields of Local2.com. "Instead of warm summer-like conditions it will feel more like fall. Temperatures are likely to be 5-10°C below normal. This will keep daytime highs buried in the teens with overnight lows in the single digits," he said.

Will this mean more Americans will be going on an overseas tropical holiday this summer? Mashable did say that much of the world will experience "remarkably warm" weather this year, unlike the U.S.

"May was the world's hottest such month on record, and it's likely that June and July will rank in the top five as well," the site concluded.
