This morning, at 10:12 a.m. PST, I spotted a rare funnel cloud over Los Angeles, CA. The air was calm and the temperature was about 68 degrees Fahrenheit (20 degrees Celsius), with mostly overcast skies and high ceiling.
The cloud was approximately 5 miles north of Culver City, and appears to be a cold air funnel cloud, rather than the larger, far more powerful type of funnel cloud associated with tornadoes. It continued drifting eastward.
Though the surface air temperatures can be quite warm in Los Angeles in the winter, temperatures higher aloft can be very cold, and it is not unusual for seasonal winter rains to bring snow to the mountains near the city.
