After slamming the southern Plains and Deep South on Christmas Day, a powerful winter storm will continue to invade more of the eastern Great Lakes and Northeast through Thursday.
As proven already on Christmas Day, the storm is complete with substantial snow, an icy mix, soaking rain, strong winds and severe weather.
Snow Totals to Top a Foot
On the storm's cold northern and western flank, substantial snow will spread will continue to invade more of the eastern Great Lakes and interior Northeast through Thursday.
More than a foot of snow will bury places from northeastern Ohio and northwestern Pennsylvania to northern Maine and neighboring communities in Canada's St. Lawrence Valley.
Cities in line to receive at least or more than a foot of snow include Buffalo, Syracuse, Rochester, Burlington and Caribou.
A half of a foot or more of snow will alone clog roads and severely disrupt travel and daily routines, but gusty winds will worsen the situation by blowing and drifting the snow around.
Soaking Rain to Bring Flash Flood Threat
Severe weather was not the only concern on the storm's warm side, but also torrential rain capable of causing urban and flash flooding.
Rain will continue to spread northward across the mid-Atlantic and southern New England through Thursday morning.
The heaviest rain and accompanying flash flood threat will reach Philadelphia and New York City tonight and Boston late tonight into Thursday morning.
Icy, Wintry Mix Another Concern
This potent winter storm is expected to unleash nothing but snow from Illinois to northern New England, while plain rain soaks the mid-Atlantic coast. In between, the snow will either mix with or the rain will start as a wintry mix.
Rain will continue to be preceded by an icy mix at the winter storm's onset along I-95 corridor north of Philadelphia.
Just because heavy snow is not falling, motorists should not take the wintry mix lightly. With sleet (ice pellets) and freezing rain involved, roads could still turn slick for a time.
Coastal Flooding/Damaging Winds Along Northeast Coast
As the heaviest rain invades the Northeast, strong winds will develop along the coast.
The burst of strong winds will then push northward along the coast into Thursday, whipping through Long Island and New York City during the evening and overnight hours of today and Boston later tonight.
The strongest winds will gust between 50 and 60 mph for a time, threatening to cause tree damage and power outages. The combination of the winds and higher astronomical tides could also lead to coastal flooding.
Conditions throughout the East Coast will improve on Friday, when a new storm may be gathering in the Deep South.
Following a bout of stormy weather that has lingered through the week, drier and more tranquil weather will move into the Atlanta area for the weekend.
Chicago is facing a mostly clear weekend with the threat of some disruptive thunderstorms on Saturday.
The peak of hurricane season, among other things, arrives in the fall.
After former Hurricane Odile battered resorts across Cabo San Lucas, Mexico, vacationers were left stranded and isolated while waiting for evacuations with sparse communication to loved ones back home.
A search for a sheriff's deputy in Austin, Texas, will continue Friday, after she called for help as she was trapped in flood waters.
Odile and other weather systems will bring both dangerous flooding and drought-busting rain in parts of Texas and the southern Plains.
