Clouds will start to increase Friday afternoon in eastern Pima county, as moisture is pushed up from the south. Some storms could even develop over the higher elevations in areas near the International Border later today.
Cochise and Santa Cruz counties will see the best chance of storm coverage today through Saturday. Some moisture will move far enough north and west to bring Tucson a chance for storms Friday night into Saturday, but it will be limited and mostly over the mountains.
Gusty winds and cooler temps will accompany these storms. Highs will drop 5 to 7 degrees Friday into the weekend.
