In Fountain Lake and, more broadly, across the state of Arkansas: As the afternoon progresses into the evening, expect mostly sunny skies with a few clouds drifting by. Temperatures will remain very hot, ranging from the mid-70s to the low 100s. Light south winds at around 5 mph will occasionally gust up to 11 mph, providing minimal relief from the heat. There is a slight chance of light rain, with the possibility of around 0.01 inches falling, but the likelihood remains low. Overall, it will stay quite warm through the evening, so outdoor plans should account for high temperatures and limited wind. No significant weather disturbances are expected overnight, and temperatures will gradually ease as the night progresses.
