Showers will diminish across the Southeast by Thursday, although cool conditions will persist through week’s end.
Meanwhile, a developing storm system will reach the northern Rockies on Thursday and areas from the central Rockies into the upper Midwest on Friday. Late-season snow can be expected from the central Plains into the upper Midwest, while rain will fall farther south and east. Storm-total precipitation could reach 1 to 2 inches from the east-central Plains into parts of the Midwest.
During the weekend and early next week, a surge of very cool air will trail the storm into the Plains, Midwest, and South, with frost and perhaps a brief, light freeze possible as far south as central Texas and portions of the central Gulf Coast States.
