This week will bring a big change in weather conditions across the area. After another warm and dry day with elevated fire danger tomorrow, several rounds of precipitation chances and cooler temperatures are expected over the remainder of the week. Our first chance for precipitation will be Wednesday over northwestern SD, where light snow is possible. Cooler temperatures arrive from north to south Thursday and Friday, along with expanding precipitation chances and breezy conditions. More widespread precipitation chances, especially in the form of snow, are anticipated this weekend into early next week. Heavy snow will be possible in spots, with the highest potential for plowable snow (4 inches or more) across northwestern and south central SD for now.
