Saturday will feature mostly cloudy skies and a few showers thanks to an area of low pressure working across the Great Lakes. But as that low pressure exits the region, skies will gradually clear through the evening. We'll be left with mostly clear skies and chilly temperatures Sunday morning. Morning lows will be in the upper 30s to low 40s, making for a cool start to the Columbus Marathon. We expect mostly sunny skies Sunday with afternoon highs in the low 60s--great weather for runners!
