Episode narrativeepisode_narrativeA dry cold front dropped south through California November 21st, ahead of an upper-level trough that arrived the next day. A very cold airmass moved into inland Central California during the 21st-22nd, bringing the first hard freeze of the season to the Kern County deserts. Low temperatures bottomed out at 23 degrees at Edwards Air Force Base). During the early morning hours of November 24, frost occurred across portions of the San Joaquin Valley floor, as a result of the same cold airmass. Low temperatures dipped to 27 near Wasco and Gustine, and 28 at the Coalinga Airport.||The upper-level trough dropped into the Great Basin early on November 23rd, while high pressure moved into southern Idaho. This resulted in a northeast wind flow over the Southern Sierra Nevada. Strong winds developed over the Sierra Nevada crest near Yosemite National Park, with the highest wind gusts of this event occurring at Tioga Pass, reaching 74 mph at 8:00 AM PST on November 23. Other wind gusts were measured between 40 to 55 mph through the Southern Sierra Nevada and locally in the Sierra Nevada Foothills as well, such as in the Mariposa area where 2 trees were downed and blocked Road 222. This ���Mono wind��� event also toppled numerous trees in Yosemite National Park, and blocked Tioga Pass Road as well.
