In Horn Lake and, more broadly, across the state of Mississippi: The late afternoon will continue to be warm, with temperatures ranging from the upper 70s to the low 90s. Expect the sky to be mostly sunny with a few clouds drifting through. Light south winds will persist, averaging around 6 mph, occasionally gusting up to 14 mph. There is a chance of scattered showers later in the evening, with some areas possibly seeing around 0.05 inches of rain. The likelihood of rain peaks at just under 60 percent, so brief showers could occur. Temperatures will gradually cool as night approaches, but conditions will remain warm overall. Keep an eye out for any sudden changes if you plan to be outdoors during the evening hours.
