Warmth will continue to spread eastward, reaching into areas of the South, East, and lower Midwest that have been experiencing cool weather. Late in the week, however, a new surge of cool air will affect parts of the Midwest and Northeast.
Meanwhile, unusual warmth will persist in much of the West, with record-setting high temperatures extending as far east as the Plains. By week’s end, cooler air will finally arrive along the Pacific Coast, signaling a pattern change.
