In Louisville and, more broadly, across the state of Alabama: Clear skies are expected through the morning and into the afternoon, bringing very hot conditions with temperatures ranging from around 70 to 95 degrees Fahrenheit. During the day, light east winds will blow at up to 9 mph, with occasional gusts reaching 28 mph. No precipitation is anticipated, so it should remain dry throughout. As temperatures climb, it’s important to stay hydrated and protect yourself from the sun, especially during peak heat hours. The light breeze may bring some relief, but overall, it will be a warm and dry day.
