A rapidly deepening area of low pressure just off the East Coast of Florida will move northeastward to the Canadian Maritimes by Friday, NWS forecaster Paul Ziegenfelder noted 08:23 UTC, January 3.
The storm will produce areas of snow and rain/freezing rain along the Southeast Coast through Wednesday evening. As the storm continues to move northeastward, snow and rain will develop over parts of the Southern Mid-Atlantic Coast that will change over to all snow by Thursday morning. The snow may be heavy over parts of the Southern Mid-Atlantic Coast overnight Wednesday.
In addition, by early Thursday morning, snow will begin to develop over parts of New England and expand into Northern New England by Thursday afternoon continuing into Friday morning. It may very heavy at times over New England.

Meanwhile, a front over the Great Lakes to the Middle Mississippi Valley then extending northwestward into the Northern High Plains and move into the Lower Great Lakes/Ohio Valley to the Lower Mississippi Valley by Wednesday evening. The associated area of low pressure will be absorbed into the greater circulation around the rapidly deepening coastal storm over the Northeast by Thursday morning as the associated front dissipates, too.

In the wake of the storm lake effect snow will develop downwind from the Upper Great Lakes overnight Wednesday into Friday. The lake effect snow will be heavy at times during this time period.
NWS' Key Messages for East Coast Winter Storm
1. This winter storm is forecast to bring the potential for a mix of freezing rain/sleet/snow from portions of northern Florida to North Carolina, and snowfall northward along portions of the Mid-Atlantic into northern New England. Blizzard conditions are possible across portions of eastern New England late Thursday.
2. If this winter storm tracks closer to the coast, it could mean more snow while a track farther east could mean less snow.
3. This system has the potential to produce strong, damaging winds possibly resulting in downed trees and/or power outages.
4. Minor to moderate coastal flooding/erosion is possible due to a combination of high tides and wave action, especially Thursday afternoon, January 4.
5. Winter Storm Watches and Warnings are in effect from north central Florida northward through eastern New England.
