Hot Stuff…100 Year Celebration

Back to above average temperatures today with the high reaching 92 degrees.  The humidity was up too with  dew points back in the 70s, that’s the oppressive zone. This pattern continues tomorrow with highs in the mid 90s and rising humidity.  Very little chance of rain expected tomorrow.

A front approaches Friday and increasing the chance of rain slightly.  I mean slightly from 20% to 30%. As the big area of high pressure is firmly east of Middle Tennessee, a strong southerly flow will keep the heat and humidity around through the weekend.


The National Park Service turns 100 tomorrow, August 25.  Yes, it was a century ago that U.S. President Woodrow Wilson signed the act that created the National Park Service.  The declaration read,  “to conserve the scenery and the natural and historic objects and the wild life therein and to provide for the enjoyment of the same in such manner and by such means as will leave them unimpaired for future generations.”

Today, the United States has 412 national parks. The National Parks Service lists 15 Parks, Trails or Historic Sites here in Tennessee.  By far the most famous is The Great Smoky Mountains National Park.  I’ve been visiting it since I was a little girl.  It’s the most visited park in America.

Like all U.S. national parks the warmer climate is having an impact on the Smokies. According to Climate Centeral temperatures are expected to rise in the future.



Changes in the national parks vary according to location… in the desert southwest they are becoming warmer and drier, parks in the northeast are becoming warmer and wetter, and parks in the Midwest and southeast are becoming warmer. These changes in climate could affect tourism and recreational activities.

For example:

  • Shorter winters could impact skiing and snowboarding
  • Increased heat, wildfires and reduced air quality could affect hiking, running and biking
  • Drought and reduced stream flow could impact lake and river recreation.

I don’t mean to be Debbie Downer on the eve of this big birthday to celebrate our great park system, but it is something we should all be aware of.

On a much light note, you can visit any of the National Parks starting tomorrow through Sunday, August 25-28.

I’ll have a weather update on Channel 4 News at 10pm.
