HAPPINESS

IS A WARM CUP

Southern California Overview:

Building high pressure will lead to warmer temperatures across Southern California through the middle of next week. The nights will still be cold in the valleys, but along the higher terrain, some wind will keep it a bit warmer. Onshore flow returns by late next week as a trough moves inland across the Pacific Northwest. This will bring stronger westerly winds across the mountains and deserts through next weekend, along with cooler conditions.

United States Overview:

A multi-day atmospheric river event will continue to impact the Northwest and Rockies with heavy rain and significant mountain snowfall Sunday and into Monday. Unsettled weather is forecast across the eastern third of the country with rain along the East Coast & wintry weather from parts of the Midwest and Great Lakes to northern New England. Generally milder than normal temperatures expected for across most of the Lower 48.

Heavy rain drenched the region, even the mountains, from 12/2 to 12/7.

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.
