Rain For Some, Heat For Everyone

By on

Today marks a return to normalcy for August: dewps in the upper 60s and afternoon storms/showers. Highs likely won’t break 90 just yet, but the heat is just getting started.

Rain is back in the forecast today. Model runs are showing activity in the afternoon (see HRRR run below). I say more activity, but we’re not expecting widespread coverage, severe weather, or anything of that nature. Anticipate unpredictable scattered showers/storms here and there, but any action could miss you altogether. Not washout material. Still could delay outdoor festivities. read more

Three Things About Last Night, & Then Good News

By on

Microbursts dropped out of severe thunderstorms.

Imagine a giant water balloon crashing to the ground. Now imagine you’re an ant on the ground. When that water hits the ground, it pushes wind away in all directions. Straight line winds race away from where the balloon hit and burst, knocking over trees. Microburst winds are intense. They aren’t tornadoes (no upward motion), but microbursts can do low-end tornado damage. read more

Storms and Heavy Rain Possible Tonight, End of Crazy Heat In Sight

By on

First things first, smoke and haze will continue today, as shown below, which has warranted an Air Quality Alert for both counties.

Near Surface Smoke – Davidson and Williamson counties outlined in the white box

For the first time in a few days, our counties are not under a Heat Advisory, but it will still feel very hot and humid. Actual temperatures will be in the mid 90’s and dewpoints in the upper 60’s, which will lead to the heat index being in the upper 90’s. Make sure to drink plenty of H20 and limit your time in the direct sun. read more

A Heat Advisory starts at 11 AM and ends at 7 PM tonight. This means the temp/humidity combo will push the heat index/feels like temp to 105° in shaded areas. Much hotter in direct sunlight. Our local heat index should hit 107° in Nashville and 106° in Franklin. You know what to do. Take breaks, guzzle water, etc. read more

Very, Very Hot

But first, a pre-forecast PSA

If I were to put “summer” in all caps, bold, underline, and italics, that’s what today will feel like. SUMMER. Heat index will almost reach 100, there is pretty much no chance of rain. At the time of writing this, we are not predicted to reach the heat index needed to issue a heat advisory (105), but we are very close. Highs in middle TN will vary in the 90s, and Nashville could hit 98. read more
