A gorgeous Fall day continues as the workweek wraps up today. Afternoon temperatures will top out in the lower 70s with mostly sunny skies. Clouds will gradually build tonight. Overnight lows will fall into the lower 50s.
A developing tropical system is in the Gulf of Mexico and will continue to move northeastward. This system will give the Tennessee Valley its next chance for rain. It will not rain everywhere and it will not rain all day. For those attending the Liz Hurley Ribbon Run, the first few hours after sunrise should be dry and the run should not be affected. Sprinkles could be possible toward the end of the run, and rain will increase in coverage heading into the late morning hours, midday, and the early afternoon. Showers will taper off after sunset as the system tracks farther northeast. Areas to the east of I-65 have the best potential for showers. Dry conditions should return by midnight. Sunday looks dry with highs in the upper 70s.
The best chance for showers and thunderstorms comes on Monday with a cold front. Rain picks up around noon in northwest Alabama, then storms will continue to slide throughout the rest of the Tennessee Valley during the afternoon and evening. Storms could be strong Monday afternoon, and a few severe thunderstorms are not out of the question. Cooler and drier air will rush in behind the rain, and temperatures drop for Tuesday with sunshine.
