In Winthrop and, more broadly, across the state of Maine: This evening, expect mostly cloudy skies with temperatures remaining mild, ranging from 64 to 67 degrees Fahrenheit. There is a strong likelihood of light rain, with total accumulation around 0.09 inches. Winds will be coming from the south at speeds up to 13 mph, with gusts reaching 35 mph. The rain may occur intermittently over the next few hours, so a light rain jacket might be helpful if you're heading outdoors. Be prepared for gusty conditions, especially if you plan to be outside for an extended period. Temperatures will remain steady through the evening, gradually cooling later at night.
