Severe Thunderstorm Watch Summary

Storms clusters are forming over the Mogollon Rim and the mountains in southeast Arizona, and the storms are expected to spread westward through late evening. The storm environment favors severe outflow gusts of 60-70 mph as the primary threat as storms propagate into the lower deserts, especially where outflow mergers occur. Otherwise, the strongest initial cells could also produce isolated large hail near 1 inch diameter.
