Heat on the Plains & across the South...
Dry and rather warm conditions are expected Sunday and early next week.
Elsewhere, a very warm weather pattern will persist nationwide into next week, except in the Northwest and along the Atlantic and Pacific Coasts. In the Northwest, markedly cooler air will arrive this weekend. Weekend highs may exceed 100 degrees as far north as the Dakotas, but extreme heat will not affect the Corn Belt.
Showers and thunderstorms will spread from the Midwest into the East. By early next week, a new batch of showers will develop from the upper Midwest into the Southwest.
