This in-depth blog post provides daily weather forecasts and analyses for Phoenix and the surrounding Southwest regions. From sunny highs to stormy possibilities, find out what’s behind this weather phenomenon, tips on staying safe, and a day-by-day breakdown as your guide to staying informed and prepared.
Over the Southwest region, the radar reveals a fascinating mix of weather conditions. Showers are moving in from the Pacific Ocean, bringing much-needed rain along the California coastline. As this system moves inland, it is delivering rain across the central California Valleys and bringing snow to the Sierra Nevada. Higher elevations are seeing the bulk of the snow, particularly near areas like Reno and Ely. The possibility of strong winds accompanies this winter weather system, especially in mountainous areas. Down in Southern California, Los Angeles and San Diego are experiencing more mild conditions with only light drizzle expected. Moving eastward, the radar shows Flagstaff is prepared for a chill, potentially receiving some light snow showers. Las Vegas appears to be on the dry side of the system, avoiding the precipitation impacting areas farther west and north. Meanwhile, the regions to the east, including Phoenix, are staying dry for now. This dynamic weather system is offering a mix of relief and challenges as it moves through the Southwest.
