Episode Narrative An upper-level low developed off Point Conception by October 27, and slowly drifted northeast toward the central California coast. The low pulled a moist, tropical airmass, including remnants from former Tropical Storm Kiko, into the central California interior on the 29th. A dry air flow became trapped in the area around the storm, clearing skies over the San Joaquin Valley during the late morning, allowing for extensive heating of an already unstable airmass. Then, in the late afternoon, a weather disturbance moved over the southern half of the San Joaquin Valley.
This combination of weather patterns triggered the worst severe thunderstorm outbreak over the central California interior in recent memory, with 15 Severe Thunderstorm Warnings, two Urban and Small Stream Flood Advisories, and a Flash Flood Warning issued between 4 PM and 8 PM. Another Severe Thunderstorm Warning had been issued earlier in the day, at 1:16 PM PDT, for the Sierra foothills in Madera and Mariposa counties. Hail up to an inch in diameter was reported, and flooding occurred in parts of the San Joaquin Valley, including sections of northwest Fresno and downtown Visalia.
Thunderstorm activity continued into the early morning hours of October 30, as a cold front moved through central California. A strong push of cold air into the region dropped the high temperature at Fresno from 80 on the 29th to 68 on the 30th. Bakersfield saw even stronger cooling, from 84 on October 29th to 63 the next day, a 21-degree cooling.
Severe thunderstorms caused several reports of downed power lines and trees, large hail, and flash flooding throughout portions of the San Joaquin Valley.
Event Narrative Newspapers and broadcast meteorologists reported a number of roadways flooded in Northwest Fresno. Numerous vehicles were stranded and water rescues occurred. Heavy rain caused a roof to collapse at an industrial plant on the northwest side of the city. Damages were estimated at 250,000 to the roof structure alone.
