A wave of summer-like heat is headed east across the United States and is set to heat up the Midwest and northern Plains over the next several days, including Mother's Day Sunday, forecasters said. The heat starts in the West, where "significant temperature anomalies" are bringing high heat on May 10. Forecasters said some parts of Southern California could reach triple digits. As the holiday weekend progresses, the heat will shift into the upper Midwest, with 90-degree and higher temperatures forecasted in the Dakotas and Minnesota, the National Weather Servicesaid. Then the high temperatures are heading into the Northern Plains, where they could approach 30 degrees above normal on May 11, the weather service said. Maps from the weather servicealso show the heat moving eastward, and by Friday, May 16, highs in the 80s and 90s could stretch from Texas to New York. But first, unusually cold temperatures are confounding the national temperature forecast with 10 to 15 degrees below normal seen across the South and Northeast, the weather service said May 10. Showers and thunderstorms in the Southeast will also last through the weekend. "Storms and heat could impact outdoor plans for Mother's Day for millions of families this weekend. It's going to be downright hot in the Upper Midwest," AccuWeather Chief On-Air Meteorologist Bernie Rayno said. "We're forecasting a soggy and stormy Mother's Day weekend across much of the Southeast. Downpours and thunderstorms could spoil cookouts and picnics."
