黑山地区10月26日迎今秋首场降雪：拉皮德城或见雨夹雪，山区可积数英寸
南达科他州彭宁顿县拉皮德城及黑山地区10月26日迎来今秋第一场有规模的降雪天气。根据10月25日的预报，冷空气南下给黑山地区带来降雪，拉皮德城可能出现今季首次雨夹雪天气。AccuWeather高级气象学家鲍勃·斯默贝克表示，黑山地区有可能降下数英寸的雪。美国国家气象局拉皮德城预报则相对保守，预计拉皮德城市区10月26日的积雪不到半英寸。两家预报的差别提醒出行者：山区降雪量不能直接套用到附近城市。
预报同时指出，白天温度偏高时落雪不易存留，清晨日出前和傍晚日落后落下的雪更容易积存。国家海洋和大气管理局天气预报中心把黑山地区和南达科他州西北部列为10月26日可能积雪的区域。这场降雪是落基山脉和北部平原多州同期天气过程的一部分，怀俄明州东部、内布拉斯加州西北部和北达科他州西南部也有积雪可能。有关部门提醒驾车者注意山区路段能见度下降和路面湿滑，出发前查看最新路况，山区行驶减速慢行。
Black Hills See Their First Snow of the Fall on October 26: Rain-Snow Mix Possible in Rapid City, Several Inches in the Hills
Rapid City and the Black Hills in Pennington County, South Dakota, saw their first sizable snowfall of this fall on October 26. According to the October 25 forecast, cold air moving south brought snow to the Black Hills, and Rapid City could see its first rain-and-snow mix of the season. AccuWeather senior meteorologist Bob Smerbeck said the Black Hills could receive several inches of snow. The National Weather Service forecast for Rapid City was relatively more conservative, projecting less than half an inch of accumulation in the city on October 26.
The difference between the two forecasts reminds travelers that mountain snowfall totals cannot be applied directly to nearby cities. The forecast also noted that snow falling while daytime temperatures are higher does not accumulate easily, while snow falling before sunrise and after sunset in the evening accumulates more readily. NOAA's Weather Prediction Center listed the Black Hills and northwestern South Dakota among the areas where snow could accumulate on October 26. The snowfall is part of a weather system affecting several states across the Rocky Mountains and the northern Plains at the same time, with snow also possible in eastern Wyoming, northwestern Nebraska and southwestern North Dakota. Authorities remind drivers to watch for reduced visibility and slippery surfaces on mountain roads, check the latest road conditions before setting out, and slow down when driving in the mountains.
