A breezy Wednesday will bring sunny spells and a high of 66 degrees to Alton and the River Bend before a much cooler Thursday. Clouds will mix with sunshine through the day, with dry weather continuing into tonight. The evening remains breezy before partly cloudy conditions accompany an overnight low of 41.
Wednesday’s wind deserves attention despite the mild temperatures. Westerly winds near 14 mph could gust to 33 mph during the day, with nighttime gusts near 30 mph. Those gusts could blow around loose outdoor items, making wind the main concern during an otherwise dry day.
