Baby It's Hot Outside.

Is it just me, or do you feel like It just keeps getting hotter and hotter outside? At Georgia Southern I know it had just begun to cool off and even started feeling nice. That is no longer the case down south. According to researchers, this is no longer the case anywhere in parts of the United States. Much of the United States is trapped under a heat "dome" caused by a huge area of high pressure that's compressing hot, moist air beneath it, leading to miserable temperatures in the mid-90s to low 100s and heat-index levels well above 100 degrees. The oppressive conditions extend from the northern Plains states to Texas and from Nebraska to the Ohio Valley. And they're expanding eastward. (FYI my beautiful people, we are eastward.) Eli Jacks is a meteorologist for the National Weather Service who describes this heat "dome" for us: When a high pressure system develops in the upper atmosphere, the air below it sinks and compresses because there's more weight on top, causing temperatures in the lower atmosphere to heat up. Thanks a lot, high pressure system.  Most people are satisfied with the gnats in south Georgia, but you knew we really wanted some extra heat, too. Notice the sarcasm people. The dome of high pressure also pushes the jet stream and its drier, cooler air, farther north — it's now well into Canada — while hot, humid air from the Gulf of Mexico circulates clockwise around the dome, traveling farther inland than normal. Combined with generally clear skies and the sun's higher summertime angle, "it gets really hot," Jacks said. According to the National Weather Service, heat domes are not uncommon, however this one is particularly interesting because of its size and duration. Americans who have been effected by this heat are learning to cope. This college kid is not a fan of the heat. But hey, i'll take it over a snow blizzard every day of the week. Fun Fact: Georgia Southern has Air Conditioning!!!
