It looks like summer continues this week. The main story is going to be this heat and humidity.
As of 8:14 AM, it is 73°F with a dew point of 68°F. Ugh.
It isn’t getting much better than this.
The high today is going to reach 94°F. Dew points hanging out in the low 70°s. Heat index values could approach the low 100°s today. Take extra precautions if you are going to be out for an extended period of time today. Keep water close, and shade even closer – if possible.
Hot and humid with highs in the lower 90s and dew points in the upper 60s and lower 70s. This will allow for heat indexes to climb into the mid and upper 90s.
A few isolated showers and thunderstorms can’t be ruled out Friday through Sunday due to the instability in the atmosphere from the heat and humidity, but we do not expect widespread storms like we saw the past couple of days. The latest run of the NAM3 model shows just a few pop up storms Friday through Sunday:
Yesterday was an eventful day weather-wise as storms bubbled up over I-65. They exceeded our expectations both in how many there were and how long they lasted. The expectation was that a few isolated cells would develop in the heat of the day, rain themselves out as the sun began to set, and leave us with a quiet night. Instead, we had numerous storms develop that were very electrically active and dropped some small hail.
Notice the H’s near us on the map. High pressure is in control today. This typically puts a lid on the atmosphere’s willingness to storm. While it’s possible the western half of the state could see a brief storm, the odds are against any one place receiving rain. Temperatures will be slightly above average with a forecast high of 91°. There won’t be much of a breeze to provide relief, so take frequent water breaks!
NWS-Nashville says:
“During the afternoon, short-range guidance depicts a few hit and miss thunderstorms, but nothing terribly organized. Instability, lapse rates, and moisture will be in place for thunderstorm development…however, low shear and weak mid-level ridging will work to keep storm coverage to a minimum. Any storms that do get going have the potential of becoming strong/severe with damaging winds and hail being the main concerns.”
