There was a brief respite before the next upper-level low pressure trough reached California on October 24th. This system tapped into a deep fetch of tropical moisture that extended across much of the northern Pacific Ocean. As a result, snow levels were high and most of the precipitation that fell in the Southern Sierra Nevada was in the form of rain. The parent low stalled southwest of the Queen Charlotte Islands, keeping the trough from digging into the southern half of the San Joaquin Valley. As a result, there was a tight precipitation gradient from north to south, with 3-4
inches of rain falling on Yosemite National Park, but only a few hundredths falling in the south end of the San Joaquin Valley and around a half inch in the Tehachapi Mountains.
Runoff from the heavy rain over Yosemite National Park caused the Merced River to rise. Fortunately the river did not flood, but it did crest at a stage of 9.51 feet at Pohono Bridge. This was only 6 inches below the flood stage at that point of 10.0 feet.
Despite the shortfall of rain over the Kern County mountains and deserts as the cold front moved through, the system generated very strong winds over the ridges and through and below the mountain passes of the Kern County mountains. There were two separate episodes of strong winds during the early morning of October 25th. The first, which began around 2:30 AM, saw gusts as high as 92 mph. The second episode, four hours later, saw gusts up to 65 mph. Trees were damaged in and near Tehachapi and Twin Oaks, and power lines were downed.
Another very cold airmass moved into interior central California with this trough. Low
temperatures on October 26th for the central and southern San Joaquin Valley ranged from 40 to 50 degrees. Low temperatures for the Valley were even colder, by around 5 degrees, the next morning, ranging from 35 to 47 degrees. The 27th also saw a moderately strong offshore flow develop over southern California. East winds over the Tehachapi Mountains funneled through the Grapevine and Tehachapi Pass into the south end of the San Joaquin Valley. The winds warmed adiabatically as they descended to the Valley floor, resulting in Bakersfield reaching a high of 78 degrees.
Warming continued on October 28th and 29th, ahead of an upper-level trough digging down the eastern Pacific off the California coast. Fresno had a high of 78 degrees both days, while Bakersfield warmed to 82 degrees on the 28th, and was only a degree cooler the next day.
The trough moved onshore during the night of October 29th-30th, bring rain and snow (above 5500 feet) to interior central California. Snowfall in the Southern Sierra Nevada ranged from around an inch at Bald Mountain to 8 inches at Tamarack Summit. Up to two inches of snow fell near Pine Mountain Club in the San Emigdio (western Tehachapi) Mountains, and light snow fell in the hills above the Tehachapi Pass. Below the snow line (around 5500 feet), up to an inch of rain fell in the Southern Sierra Nevada and the foothills, except at the Lake Kaweah Pool, where
1.20 inch of rain was recorded. On the San Joaquin Valley floor, rainfall amounts were as high as 0.36 inch. (By coincidence, the amounts of rainfall at both Bakersfield and Fresno on October 30th were the same as the monthly totals for May, the last month prior to October in which measurable rain fell.) In addition, wind gusts up to 63 mph developed overnight not only over the mountains but also along the west side of the San Joaquin Valley.
October ended with the upper-level trough moving east of California, allowing an upper-level ridge to build into the state. With a stable airmass, breaks in the high clouds over the region on the 31st allowed patches of dense fog to develop on the San Joaquin Valley floor by daybreak, especially in the Merced area. Otherwise, October ended on a quiet weather note.
