After weeks of the same broken, skipping record, it finally looks as though our weather pattern is going to change. And whether you've liked these cooler-than-normal summer days, we're going to tap into some serious summertime heat by this weekend.
For most of this summer, the jet stream has been sitting to the south of the Old Dominion. Why is this important? The jet stream does two things: 1) steers storms, and 2) marks the line between cold air to the north and hot air to the south. With its position over the Carolinas for most of the summer, we've seen temperatures mainly at or below normal. At last check, the hottest temperature at the Charlottesville airport was 92° back on July 16th, and 94° at the McCormick Observatory on the same date. Starting this weekend, the jet stream will shift and pass directly through the Great Lakes. This will allow hot air (the same hot air that brought record highs to Seattle, Washington, not too long ago) to dominate the eastern United States and send temperatures well into the 90s. If I read correctly, New York City has yet to hit 90° this summer. That's about to change. Keep in mind that the humidity will be high, preventing your body from cooling off quickly. This will lead to heat indicies - a measure of temperature & humidity - well above 100°.
Heat-related illnesses kill hundreds of people every year. Heat stroke, dehydration, and heat exhaustion are three of the most well-known. Some ways to keep cool in high heat: 1) Drink plenty of non-caffeinated, non-alcoholic beverages; 2) wear light-colored clothing; 3) limited direct exposure to the sun; 4) watch out for pets, the young, and the elderly; and 5) take frequent breaks when working outdoors.
So, it's going to get hot this weekend. That gives us all the more reason to head to the swimming pool and eat snow cones. Guess I'll have to brush the dust and dirt from my air conditioner. it's been a while since I've used it!
