Residents in Central New York should prepare for a shift in weather conditions as the weekend progresses. While Sunday is expected to be pleasant for outdoor activities, including boating on Lake Ontario, Oneida Lake, and the Finger Lakes, Monday's forecasted rain could disrupt plans. The rain may also lead to wet and slippery conditions on roads and outdoor surfaces. Additionally, the return of heat and humidity later in the week could bring thunderstorms, some of which may be strong or severe.
