Watching for Shortwaves & the Return of Rain

Today – More Humidity – High: 94°

Humidity was low this weekend thanks to dewpoints in the 50°s and low 60°s. This ends today.

The dewpoint will move into the mid 60°s, a decent crank-up of humidity.

Meanwhile, we’re watching for shortwaves — ripples in the atmosphere that can set off rain and thunderstorms.

We see one that may bother us tonight, but it’s pretty small.

HRRR has it coming down I-24 this afternoon and tonight, then breaking apart before it really gets to us:

So, maybe a chance of rain tonight, but probably not. However, if we do end up getting something, there’s a small chance of a strong thunderstorm.

Tuesday – Stronger Shortwave; Better Rain Chance – High: 93°

A stronger shortwave will be sitting to our NW, ready to roll in sometime Tuesday night into Wednesday morning:

Thunderstorms – a few possibly strong – are possible.

Wednesday – Decent Chance of Rain – High 91°

That rainmaker circled above may arrive and scatter showers and thunderstorms all across Middle TN. Exactly when and where, we don’t know.

Right now, we think the stronger storms will stay west of us:

Even those storms to our west won’t be that strong.

The best rain chance of the week arrives Thursday.

Wet & Stormy Thursday & Friday

How stormy? “Predictability too low,” says the Storm Prediction Center.
