A cold front marched eastward across the United States on Friday, threatening to bring heavy rain and thunderstorms from Florida to the Northeast and snow to New England.
It was part of a broad storm blamed for at least three deaths as it moved across the nation earlier in the week.
The system will bring much cooler temperatures to the East Coast during the weekend, forecasters at the National Weather Service said.
"Mixed wintry weather is also expected for parts of the Great Lakes and into northern New England, where the air is cold enough for that," the forecasters said.
The storm brought heavy snow to Colorado, South Dakota and Minnesota earlier in the week. In Nebraska, the state patrol said 37-year-old Lisa Conrad, of Berea, died from exposure Tuesday after abandoning her disabled car and trying to walk to her home a mile away during a blinding snowstorm.
The system spun off a tornado that killed one person and injured five in Mississippi on Thursday, and brought, hail, damaging winds and twisters to Arkansas, Texas, Oklahoma and Kansas.
High winds and heavy wet snow downed power lines in several states, and outages persisted Friday in nearly every state from Missouri eastward.
A utility worker in Ameren, Miss., was electrocuted Thursday while helping restore power knocked out by the storm in the St. Louis area, the company said.
Missouri was hardest hit with about 5,000 electrical customers without service Friday, while 3,000 were without power in North Carolina, utility companies said.
