亚利桑那州马里科帕县凤凰城万圣节周末将迎降雨：11月1日雨势最大，高海拔地区或再添2英寸降水
亚利桑那州马里科帕县凤凰城地区将在万圣节周末迎来一轮降雨，预报于2026年10月28日发布。预报指出，10月31日星期六白天中段天气仍以多云为主、相对平静，但傍晚之后出现零星降雨的可能性上升，夜间外出者遇到零星雷阵雨的概率更高。11月1日星期日将是本轮降雨较强的一天，降雨从上午开始、中午达到高峰、傍晚减弱，11月2日星期一天气转晴。星期日的降雨水汽来自一股规模不大的大气河，降雨形态较为传统，雨水自西南方向随槽线而来，最强降雨预计出现在莫戈隆边缘及亚利桑那州东南部。预报估计，中亚利桑那州高海拔地区还可增加约2英寸降水，低海拔地区增加约0.5至1英寸，伴随雷阵雨的局部地区雨量可能更高。由于两轮降雨间隔很近，低洼地区需留意局部积水。气温方面，10月30日星期五和31日星期六最高气温维持在70多华氏度，11月1日星期日可能降至60多华氏度，三晚最低气温在60多华氏度。预报还提到，凤凰城上一次万圣节出现可测量降雨还是1988年。
Rain Coming to Phoenix, Maricopa County, Arizona, for Halloween Weekend: Heaviest on November 1, with About 2 More Inches at Higher Elevations
The Phoenix area of Maricopa County, Arizona, will see a round of rain over Halloween weekend, according to a forecast issued on October 28, 2026. The middle of Saturday, October 31, is expected to remain mostly cloudy and relatively calm, but the chance of isolated showers rises into the evening, and late-night revelers have a higher likelihood of catching stray storms. Sunday, November 1, is meant to be the greater rainfall day, with rain beginning in the morning, peaking during the middle of the day and fading by the evening, leaving clarity by Monday, November 2. Sunday's moisture comes from a modest atmospheric river, in a more traditional pattern in which the trough brings moisture from the southwest, with the heaviest totals expected along the Mogollon Rim and in southeastern Arizona. Higher elevations of central Arizona could add another 2 inches of precipitation, while lower elevations could see an additional half inch to 1 inch, with locally higher totals possible with thunderstorms. With the two rainfall events close in time, localized flooding in low-lying areas is possible. Highs on Friday, October 30, and Saturday will stay in the 70s, Sunday may fall to the 60s, and lows on all three nights should stay in the 60s. There has not been measurable rain during a Phoenix Halloween since 1988.
