HAPPINESS

IS A WARM CUP

Southern California Overview:

Weakening high pressure aloft, and an incoming Pacific trough, will flip our winds back onshore, beginning the return of marine air tonight, with possible coastal fog. Strengthening sea breezes will spread cooling and humidity well inland on Wednesday. By Thursday, strong westerly winds will drive further cooling across the mountains and into the deserts. Winds will flip again on Friday, becoming northerly and gusty below the passes and canyons. This will return Southern California to Santa Ana conditions again this weekend, complete with locally gusty northeast winds, low humidity, and above average daytime temperatures west of the mountains.

United States Overview:

Excessive rainfall and flooding potential continues across the Pacific Northwest. Moderate upslope snow forecast across the central and southern Appalachians today. Well above average and potentially record-breaking warmth forecast across the central United States over the next few days.

Heavy rain drenched the region, especially the mountains, from 12/2 to 12/7. Storm totals for the period: 27.79 inches in Lake Arrowhead (believed to be a 100 year rainfall), 23.73 inches in Palomar Mountain, 18.72 inches in Big Bear Lake, 17.85 inches in Idyllwild, 9.14 inches in San Bernardino, 7.63 inches in Redlands, 6.21 inches in Santa Ana, 5.19 inches in Riverside, 2.99 inches in San Diego, 2.73 inches in Palm Springs, but only 0.66 inches in Victorville and 0.28 inches in Barstow! At least two homes were destroyed by floods and debris flows in Mill Creek Canyon. Debris flows and floods damaged homes and roads in Wrightwood and Lytle Creek. Homes and businesses were flooded in Redlands and Palm Springs. Many roads across the region were flooded and washed out. Scuba divers could not recover a Montclair man believed drowned in floodwaters. Strong storm winds caused power outages. On this day 9.43 inches of precipitation fell in Big Bear Lake, the greatest daily precipitation amount on record. Incredibly, only 0.07 inch fell in Victorville on this day.
