West:
A series of Pacific storms will produce heavy rainfall, very heavy snowfall in the mountains, strong gusty winds, dangerous coastal surf, and possible coastal flooding into early next week. The heaviest precipitation is expected today through Saturday morning. Total precipitation up to 6 to 12 inches (rain or melted snow) is possible through the weekend. Heavy rain could result in flash flooding and, particularly in the burn areas of southern California, mud and debris flows. At lower elevations in California, 2 to 3 inches of rainfall is possible. With a few exceptions, river flooding is not a major concern, as soil conditions have been dry and reservoirs have been at low levels. Minor flooding is forecast along the Eel River at Fernbridge and along the Sacramento River at Tehema. As of Thursday afternoon, snow levels ranged from 4000 feet in the north to 8000 feet in the south. Snow levels will lower through the weekend to 1500 feet (north and central) and 3500 feet (south). Snow accumulations of 2 to 5 feet are expected at the pass levels through Sunday, with several feet of additional snow possible at higher elevations. Wind gusts exceeding 100 mph are possible today in the Sierra Nevada, with blizzard conditions in the mountains near the California-Oregon border and in the northern and central Sierra Nevada. The coast from southern Oregon through southern California will experience dangerous high surf and possible coastal flooding conditions, with wave action peaking in northern California tonight through Saturday morning.
Northeast:
A frontal system moving along the Canadian border will produce light rain/drizzle and even freezing rain along the border in Upstate New York and northern New England. The high pressure centered in the Southeast will produce Southwest wind flow with temperatures increasing into the 30s and lower 40s across the Mid-Atlantic with 20s and the teens in northern New England. Increasing temperatures through the weekend will result in snow melt and ice jams which may produce localized flooding.
Midwest:
High pressure moving east of the area will result in increasing gusty (20 to 30 mph) south-to-southwesterly flow and rapidly increasing temperatures in the Plains and Midwest. Temperatures will be 10 to 25 degrees above average across most of the Plains and Midwest this weekend. Warmer air will result in snow melt and ice breakup, ice movement and possible jamming on area streams and rivers. Resulting in localized flooding this weekend in the Midwest and western Great Lakes.
South:
High pressure over the region will produce generally clear skies and very cold dry air. Low temperatures will range from the teens from eastern Tennessee and North Carolina to central Georgia and 20s into northern Florida. A warming trend is expected over the weekend as the high pressure moves east and south-to-southwesterly wind flow returns (NWS, Media Sources)

The minor effects of the recent cold snap will be gone by this weekend, when warmer temperatures are forecast to prevail. (NWS)
A significant warm up this weekend and early next week will cause rapid snowmelt. This is expected to combine with periods of rain into early next week leading to the possibility of flooding.
