Heat index of 102 degrees expected Tuesday as temperatures keep topping averages

If you’d held out hope for a break from the heat this week, maybe you should give it up now.

The National Weather Service is predicting an actual high of 97 degrees Tuesday and a heat index of up to 102, with only a 20 percent chance of rain and no breeze beyond a 5-10 mph wind from the East.

The rest of this week’s not looking much better, with highs in the mid- to upper 90s through Sunday.

To native Southerners, the heat may seem typical for August, but temperatures this summer have shown a trend: Most daily highs are hitting 3-5 degrees or more above average.

According to AccuWeather.com, the high for this date historically averages 92 degrees. AccuWeather’s records since June show that so far the recorded high has topped the historical average on 52 days, with only eight days cooler than the average and 10 days either matching or coming within 1 degree of the average.

According to AccuWeather, the high temperature typically averages in the low 90s this time of year, yet the recorded temperatures keep hitting the mid- to upper 90s, with five days in July and one this month reaching 100 degrees or more.

You might think the recent dearth of rain to cool things off would bode well for Thursday night’s Perseid meteor shower, but even that hope could turn false: The forecast says skies will be mostly cloudy here that night, with a 20 percent chance of rain and thunderstorms, and a low of 77 degrees.

The meteor shower’s to become visible about 10 p.m. Thursday and continue through dawn, with dozens of meteors hourly streaking across the sky just before daybreak Friday, reports the online news service Science@NASA.
