美国东部寒潮将持续至感恩节前消退 气候预测中心称感恩节周大部地区气温偏高 南部平原或迎今冬首冻
据国家气象局的预报，美国东部正经历一场寒潮，纽约州部分地区降雪超过一英尺，东部大部地区夜间低温降至华氏20多度至30多度。预报人员说，这股冷空气将在11月中旬缓慢消退。
美国国家海洋和大气管理局气候预测中心的 Anthony Artusa 说，到11月20日前后，异常偏暖的天气将覆盖落基山脉以东的大部地区，只有远西地区气温低于常年。感恩节周全美大部地区将维持偏暖格局，目前没有迹象显示那一周会出现强风暴，大范围的重大出行干扰有望避免。
例外是南部平原。Artusa 说，俄克拉荷马州与德州在感恩节周可能迎来今冬第一次冻结天气。AccuWeather 则预计，感恩节出行周南部地区与加州将有降雨，加州高海拔地区有降雪；东北部在出行周初以干燥为主，之后降雨机会增加，纽约市 Macy's 感恩节游行时段预计以干燥为主、清晨偏凉。
Eastern cold snap to fade before Thanksgiving; Climate Prediction Center expects a mild holiday week for most of the U.S., with a possible first freeze in the southern Plains
Parts of New York saw more than a foot of snow and much of the eastern half of the country is facing lows in the 20s and 30s Fahrenheit in a cold snap, according to the National Weather Service. Forecasters say the cold will slowly fade in mid-November.
By around November 20, above-average temperatures should encompass all areas east of the Rockies, NOAA's Climate Prediction Center said; only the Far West will be cooler than average around that time. Thanksgiving week should bring a mild pattern across much of the United States, according to Anthony Artusa, a meteorologist with the Climate Prediction Center, and he does not see any powerful storms that week, so widespread, major travel disruptions could be avoided.
One exception is the southern Plains, where Oklahoma and Texas could see their first freeze of the season during Thanksgiving week, Artusa said. AccuWeather expects rainy weather across the southern tier of the nation along with California, where snow will fall at higher elevations; the Northeast should start the travel week mainly dry, with rain potential increasing later in the week, and mainly dry conditions are expected for Macy's Thanksgiving Day Parade in New York City, though it could be chilly early in the day.
