Enjoy Brief Cooler Temperatures; Expect heat belt to expand in 30 years

About 70 percent of Americans are experiencing cooler temperatures only possible during autumn. While it’s forecasted to be cooler than average in much of the eastern two-thirds of the country over the coming days, parts of the Northwest and California will bake, with temperatures 10 to 20 degrees above normal.

The cooler weather is coming from the Arctic. According to the Washington Post, using NOAA’s HYSPLIT model, which simulates the movement and origins of air parcels all around the world, we can deduce that this air mass actually began over the Arctic back on Aug. 3. It was north of Greenland, then traced a loop before sauntering south over Hudson Bay and settling over the interior Northeast and Mid-Atlantic over the weekend. Now it’s spread across much of the eastern United States.

In a study from the nonprofit First Street Foundation, the heat risk prevails in the United States over the next 30 years. It uses heat index, which measures how hot it feels outside by including temperature and humidity. At least 46 percent of Americans will be in the heat belt line of 100 – plus and over the 30 years, increasing to 63 percent of the population.

The triple-digit heat days will be increased to 20 extra days per year and will be in most of the southern states. Texas and Florida could see over 70 consecutive days with the heat index over 100 degrees Fahrenheit.

Days like these won’t last, so enjoy them as much as you can.
