Excessive Heat Warning issued. Dangerous heat possible

News

Just because it’s August doesn’t mean it magically stops being hot out. It is still summer after all and the mercury can rise just as high in August if not higher than July, and that’s exactly what we’re talking about across the Tennessee Valley and the Southeast.

Excessive Heat Warning Valid Augst 13, 2019

The entire Tennessee Valley with a couple of exceptions will be under an Excessive Heat Warning on Monday, August 12, 2019, starting at 7:00 PM and running through 6:00 PM Tuesday, August 13, 2019. An excessive heat warning is issued when the heat index climbs higher than 110°. In the case of Tuesday, the heat index will near 114° in most locations.

Jackson and DeKalb Counties in NE Alabama and Giles County in southern Middle Tennessee will remain under a Heat Advisory during the same time period.

Regional Watches/Warnings

We’re not alone when it comes to the extreme heat. 12 states are sitting under a heat advisory or excessive heat warning.

1:45 PM August 12, 2019 heat indices across the Southeast.

As of 1:45 PM heat indices in some locations across Arkansas, Missouri, Louisiana, and parts of Alabama, and Mississippi have soared higher than the 110° mark and are approaching 115°. It is at this point that the heat can become dangerous.

Outside temperature verse inside car temperature

The heat becomes especially dangerous when referencing the inside car temperature verse the outside car temperature. Notice in the chart with an air temperature of 95° the inside car temperature quickly rises to 129° after just 30 minutes.

Futurecast Road Temperatures

Something we don’t commonly think about are the road temperatures. This is the temperature of the pavement. It is important to think about this when walking your dog or trying to go barefoot. The road temperature on Tuesday will exceed 125° across the Tennessee Valley.

Heat Safety Tips

These tips may seem like common sense, but they are so important to remember when the temperature climbs as high as it’s forecast the next couple of days.

Our next chance of relief looks to come Wednesday when some rain moves into the Tennessee Valley.
