The Desert Southwest is set for a significant weather change this weekend. After a pleasant, warm Thursday with clear skies and light winds, temperatures will dip by 5-10 degrees starting Friday. A low-pressure system will bring cooler conditions, gusty winds, and slight chances of rain, especially in southeast Arizona. Wind advisories are in effect for Imperial County, with gusts up to 55 mph possible. As the system progresses into Saturday, temperatures are expected to be 10 degrees below normal, with highs in the mid-60s for lower deserts. This cooler trend may continue into next week, with additional rain chances, the NWS stated.
