Across the Southwest region, the radar reveals quite a mix of weather conditions.

Heading into southern Utah, Cedar City could see some unsettled skies with clouds, although no rain or snow is presently in the forecast there. Arizona’s higher elevations, particularly around Flagstaff, are facing some potential light snow showers as cooler air dominates the region. Phoenix remains dry and warm, providing a nice break for outdoor activities. The southern expanse from Los Angeles down to San Diego is experiencing mild conditions with only a few passing clouds. Along the coast, the weather remains calm.
This evening in Phoenix, expect mostly cloudy skies transitioning to partly cloudy conditions. Temperatures will start at 97 degrees around 9 PM, cooling to 91 degrees by 11 PM, and further to 86 degrees by 1 AM.

Expect a dynamic weather day across the Southwest with a changing pattern through the weekend. A high-pressure system will maintain clear skies and dry conditions for much of Arizona and New Mexico.

Look for thunderstorms to develop in parts of Nevada and into western Arizona by Saturday evening. The storm potential comes with the chance for gusty winds and localized flooding. Be prepared for cooler temperatures as the frontal system moves in, dropping highs by about ten degrees into the low 70s. Stay alert for any weather advisories over the next 48 hours.
