Beneficial Rain, Snow On The Way For The Southwest

Phoenix and Las Vegas are two low-elevation cities that could pick up around a month's worth of rain in a matter of days as these waves of moisture move across the interior. Rainfall amounts in Phoenix could approach or exceed 1 inch by the middle of next week, while Las Vegas may receive around 0.50 of an inch. Each city averages 0.87 of an inch and 0.56 of an inch in January, respectively. COURTESY/ACCUWEATHER

As the storm train continues to slam California into the third week of January, happens when a line of warm, moist air flows from near the islands across the Pacific Ocean to the West Coast, which falls as heavy rain when it reaches cooler air over land. These “rivers in the sky” can be more than 1,000 miles long and carry more water than the Mississippi River.
