South takes hit

Storms were only one aspect of the extreme weather across the Southeast as heavy rain soaked much of the region. Rain around the slow-moving cold front prompted flood watches and warnings from southeastern Louisiana to central Georgia through Tuesday afternoon.

Those states could get 3 to 5 inches of rain, CNN meteorologists said.

The Southeast and Gulf Coast may see severe storms Monday, with heavy rainfall and gusty winds, the Storm Prediction Center said.

Warmer weather

Daytime temperatures were expected to climb Monday into the 40s in much of southern Connecticut, Rhode Island and Massachusetts, where rain may fall as well.

That would help melt snow, though it could make what's there heavier and increase the risk of roof collapses. There were reports Sunday of a barn, a sports facility, commercial buildings and other buildings suffering cave-ins, Malloy said.

Freezing rain will change to rain as temperatures warm in the Northeast on Monday. But overnight lows will dip below freezing, causing melted snow to refreeze on roads.

A weak system will move through the area on Wednesday and will drop dustings of snow across the area, but the system should clear out by Thursday morning.

The mix made for a messy Monday morning commute into cities such as Boston, though schools remained closed there and in many other locales as the snow clean-up effort continued.

Flights resumed Sunday at Boston's Logan Airport and Amtrak restored limited service.

"We're working as hard as we can," Rhode Island Gov. Lincoln Chaffee said of efforts in his state. "We're seeing efforts every hour."

Lots and lots of snow

The blizzard that began burying the Northeast on Friday was historic by many measures -- most of all, by the amount of snow that fell.

In Hamden, Connecticut, for instance, 40 inches of snow made it difficult for plows to get on the roads. CNN iReporter Mia Orsatti said streets there had transformed into "white, wide, soft blanket(s) of snow."

Lesser depths still led to major headaches, especially when combined with hurricane-force wind gusts, storm surges and snow drifts.

"There's a ton of snow, and there's nowhere to put it," said Lena Berc of Boston, where 24.9 inches fell. "So it's really frustrating to find nooks and crannies."

Many still without power

About 270,000 utility customers were in the dark late Sunday, down from 635,000 a day earlier.

The outages were the result of a combination of whipping winds and power lines sagging, and sometimes snapping, under the weight of wet snow and ice.
