Early-morning clouds over over Williamson and Davidson Counties have disappeared.
Some puffy cumulus clouds are appearing over us, but they’re not blocking sunshine from reaching the surface.
High temps will reach into the low 90’s, with dewpoints remaining in the low 70s. It’s going to feel close to 100° this afternoon.
You guessed it: the typical summertime pattern today.
Pop-up showers and storms are the story of the day. A high temperature of 91º expected today in Nashville. Dew points in the low 70º range.
It is the Monday morning after a holiday week, so let’s keep this short and to the point. It is going to be hot, and it might rain.
Isolated showers and storms will be prevalent Monday, Tuesday, and Wednesday. As typical for summer, we do not know exactly when, or exactly where.
Expect heat and humidity with pop-up afternoon/early evening showers and storms possible this week. Exactly when and where is not knowable.
Dewpoints near/above 70° announce near-oppressive humidity.
Muggy air returns today. It’ll be more humid than it was yesterday. Dewpoints near/above 70° announce near-oppressive humidity returning this week.
After cool/cloudy Saturday, today we’re back to normal: hot/humid, pop-up afternoon/early evening showers and storms possible. NWS-Nashville wrote:
Yesterday’s frontal passage left us right on the fringes between two air masses. GOES-16 Water Vapor imagery (below) does a great job showing this: dry air can be seen as the warm, orange color; moist air is the cooler, blue color.
Today’s lunchtime thunderstorm is prompting forecast changes. We thought tonight would be rainy/stormy, but it appears this big thunderstorm has taken all the fuel needed to maintain storms later today and tonight.
NWS Nashville has placed Williamson and Davidson Counties in a Heat Advisory between 11 AM and 8 PM today.
More from NWS Nashville:
The combination of heat and humidity will lead to an increased risk of heat-related stress and illness. The very young, the elderly, those without air conditioning, and those participating in strenuous outdoor activities will be the most susceptible. Also, car interiors can reach lethal temperatures in a matter of minutes.
The United States of America is turning 242 years old today (no… not 2018 years old…)
[Editor’s Note: that’s The Intern’s joke. I would have led with: “We’re celebrating our 242nd birthday with a heat index of 242°.” You decide which joke is better.]
Cloud cover should increase this afternoon, tossing shade and bringing our high temps down. The high will hover around the low 90s. Dewpoints remain in the low 70s – humidity will be “oppressive.”
