Activity on the 25th was mostly concentrated across higher terrain areas of eastern AZ, fueled by MLCAPE values approaching 2000 J/kg. Strong to severe thunderstorms developed during the afternoon hours, producing rainfall accumulations of over 2 inches in less th...

Thunderstorm activity during the afternoon hours developed across southwest Maricopa County as well as across the Mogollon Rim area. By the mid to late evening hours, colliding outflows from these storm complexes led to the development of additi...

Severe thunderstorms moved through the Tucson Metro area on October 11th causing multiple reports of 1 inch hail and uprooted trees on the southeast side of the metro. Additionally, as this storm moved northward c...

Beginning late on the 8th through the 9th, very anomalous moisture from Tropical Cyclone Priscilla surged northward with PWATs rising to over 1.5+...
