The Southwest region’s radar shows rain moving in from the Pacific northwest, bringing showers to Redding and surrounding areas. Reno is experiencing some light rain as the system pushes southeast. Ely and the areas in eastern Nevada see a mix of rain and snow, hinting at changing conditions as temperatures drop. While Flagstaff is currently dry, clouds indicate potential precipitation moving in later. Southern cities like Las Vegas, Phoenix, and San Diego remain clear for now, enjoying a respite from the stormy weather.
For this evening in Salt Lake City, temperatures begin at 83 degrees at 9 PM, and cool to 67 degrees by 1 AM.

A developing weather pattern will bring increased precipitation to the Southwest, beginning Tuesday. Expect rain showers to sweep from Northern California towards Arizona, with moderate to heavy rainfall in the San Bernardino Valley. Cold air from the north is colliding with moist air from the Pacific, leading to potential thunderstorms in the region. Temperatures in Southern California and Arizona will notably cool, with daytime highs dropping by around 10 degrees. Watch for slick roads and lower visibility especially across mountain passes as rain persists through Wednesday.
The UV index in Salt Lake City is high at 8 today, with a burn time of just 17 minutes under direct sunlight. For tomorrow, expect a moderate UV index of 6, with a burn time of 23 minutes. If storms roll in, they’ll provide a natural shield, reducing direct sun exposure.
