2025 Summer Outlook: What to expect in Middle Tennessee
During the average summer in Middle Tennessee and Southern Kentucky, we see high temperatures and high humidity compared to folks to our north. The average high temperature for Nashville during the summer months gets as high as the low 90s.
Lows are typically in the upper 60s and low 70s.
The warm overnight temperatures are partially caused by the high humidity that's common here. Dew points are routinely in the 70s from June through August. This makes it feel even hotter.

The Climate Prediction Center issues seasonal outlooks, and they are forecasting slightly warmer than normal temperatures from June through August.
Their forecast is for near-average precipitation.
The forecast for above-average temperatures is no surprise. Out of the last 10 summers in Nashville, 7 of them have featured warmer-than-normal temperatures.
The precipitation trend is also above average. Eight out of the last 10 summers featured more rainfall than normal.
This spring was the 5th wettest on record in Middle Tennessee. Let's look back at Nashville's wettest springs to see if it had any impact on what we saw in the summer.
During the years that we had record rainfall during the spring, most of the following summers featured cooler-than-normal temperatures. This makes sense because a saturated ground favors higher humidity. Air with a lot of moisture in it takes more energy to heat up.
There wasn't much correlation between record wet springs and summertime rainfall. But if you're tired of the rain, 6 out of 10 of those summers had below-average rainfall.
⏩
It's unlikely it will be as hot and as dry as last summer, but it will feel hot no matter what. The extreme heat and humidity start this weekend. The forecast for Saturday, June 21st, and Sunday, the 22nd, is for temperatures in the mid-90s and feels like temperatures over 100°.

What flood insurance does and does not cover
SEATTLE — Though natural disasters cycle across seasons and regions in the U.S., it's often a shocking discovery for property owners how expansive and expensive flood and water damage can be when a major storm devastates their homes, businesses and communities. That's because oftentimes insurance doesn't cover what the policyholder thinks it does — or thinks it should.

Few Texas Homeowners Hit by Extreme Rains Have Flood Insurance
The narrow canyons and shallow soils in the central Texas area pummeled by recent storms long ago earned it the nickname of 'Flash Flood Alley.' Yet only a fraction of homeowners there have flood insurance, data show. In Kerr County, where the Guadalupe River swelled, killing more than 90 people, only 2% of homeowners hold federal flood insurance. In neighboring Kendall, another hard-hit county, that share is less than 5%.
