Philadelphia ( CNN ) -- Bob and Debbie Burns endured three dark and powerless days after Hurricane Sandy . When the lights went out this time -- the result of a powerful winter storm -- they were ready . Candles give a pleasant glow to their living room in Abington Township , Pennsylvania , a Philadelphia suburb . Burning logs in the fireplace give at least a little warmth . They have hot water , and a gas stove to cook on -- both products of their experience in the wake of Sandy -- the 2012 hurricane that caused widespread damage and power outages up and down the Eastern Seaboard . And they huddle under blankets and pass the time talking . `` We 're very content , '' Bob Burns told CNN on Wednesday night . `` It gives us more quality time to sit and talk . '' The couple are among an estimated 578,000 who remained without power early Thursday in the wake of Wednesday 's snow and ice storm , according to a CNN tally of outage figures provided by electric utilities . In Philadelphia alone , electric provider PECO said that at the peak of the outages midday Wednesday , more than 623,000 homes and businesses were without power . That number had fallen to about 431,000 Thursday afternoon , according to the company . The vast majority should get their power back by Friday , but for some , the wait could stretch to Sunday , spokeswoman Debbie Yemenijian told CNN . After all , it 's the second-most damaging storm in the company 's history , PECO said . Crews from Arkansas , Illinois , Massachusetts , New York , Ohio and Canada have joined PECO 's workers to fix the damage , the company said . In all , more than 1,500 workers are in the field , it said . A similar number have been fielded in the Baltimore area , where some 45,000 homes and businesses remained without power early Thursday , utility Baltimore Gas and Electric Co. said on Twitter . Tens of thousands also remained without power elsewhere in Pennsylvania and New Jersey , with a handful of outages remaining in Ohio as well . The storm that caused all the problems moved out of the Midwest on Wednesday , bringing more than 10 inches of snow to Boston , 13 inches to other parts of Massachusetts and 4 inches of snow and a quarter-inch of ice to New York . The wet , heavy snow was a delight for children who got a snow day , less so for everyone else . `` Harder to push , not as easy actually to plow , '' said Boston snowplow driver Nick Sfravara . `` It 's definitely a challenge to get this stuff out of the way rather than the light stuff . '' Another system is forecast to bring snow to the region this weekend , but it 's not expected to produce as many problems , according to CNN meteorologists . The central United States will continue to deal with unusual cold , with wind chill warnings or advisories posted in more than a dozen states where highs are expected to be 20 to 40 degrees below average .
