[Weather Channel] Winter Storm Thor: Snow, Sleet, Ice Mess In South, Midwest, East
A final swath of snow, sleet and freezing rain will lead to dangerous travel from the Southern Plains into the Ohio Valley and East starting Wednesday.
There is also the risk of heavy rain, which brings the threat of flooding, before the rain changes to snow.
The second chapter of Winter Storm Thor spread snow and a little ice into parts of the Midwest and Northeast Tuesday.

Winter storm watches and warnings have been hoisted in parts of the South and Ohio Valley, ahead of Thor’s final phase beginning Wednesday.
All told, more than 88 million people – were under some kind of watch, warning, or advisory for winter weather related to Winter Storm Thor as of Wednesday morning.
The daily forecast details from coast-to-coast are below.
Wednesday – Wednesday night
Wednesday Night’s Forecast
Rain, with perhaps even a rumble of thunder, is possible into early Wednesday from the Ohio Valley into the Mid-South region. This rain could be locally heavy, with 1 to 3 inches of rain possible.
Due to this rain, saturated ground from recent rain, as well as snowmelt adding to water levels in creeks, streams and rivers, flood warnings are in effect in parts of the Ohio and Mississippi Valleys.

The arctic front will gradually push to the south and east. At the same time, an active jet stream and moisture will intercept this sagging front.
As our forecast map for Wednesday shows, a change to snow, sleet or freezing rain is forecast to occur in a swath from the Ohio Valley to the Tennessee Valley and into the Southern Plains.
In some places temperatures will fall rapidly during the day Wednesday, causing rain to change over to wintry forms of precipitation and eventually all snow. (This is why you may be seeing puzzling combinations such as “icy, high 47” on the forecast map.) The rapid fall in temperatures could cause wet roads to turn into a sheet of ice while a significant amount of snow falls onto them.
If you have travel plans, bear in mind that roads may be difficult to treat as snowplows may be able to remove the snow, but not the sheet of ice underneath.
Wednesday night, rain should mix with or change to snow in a swath from the West Virginia and western Pennsylvania to southern New England, including theNew York City, Philadelphia and Pittsburgh metro areas. Farther south, precipitation may transition to freezing rain or sleet, before switching to snow around sunrise inBaltimore and Washington, D.C.
Mainly light snow will shift south from the High Plains of eastern Colorado into eastern New Mexico, before ending Wednesday night.
Lingering freezing rain, freezing drizzle or sleet is possible Thursday morning in parts of the Deep South and Southeast.
A second area of sleet and freezing rain is possible Thursday in parts of Virginia and northern North Carolina, before changing to snow later Thursday as Winter Storm Thor exits.
Meanwhile, accumulating snow will fall from the Mid-South and parts of the Tennessee Valley into the Appalachians, Mid-Atlantic states and I-95 corridor into southern New England, making for a potentially tricky pair of commutes from Boston to Washington, D.C.
The snow will end from west to east through the day, pushing off the East Coast Thursday evening.
Here’s our latest snow and ice forecast:
- Heaviest snow potential: 6 inches of snow or more is possible for parts of southeast Missouri, far southern Illinois, far southern Indiana, Kentucky, far northern Tennessee, southern Ohio and West Virginia eastward into the Delaware Valley and New Jersey. Parts of Kentucky may see up to a foot of snow, locally.
- Accumulating snow will also blanket parts of Arkansas, Oklahoma, north Texas and the Texas Panhandle, southern Kansas as well as the southern Rockies and adjacent High Plains. In the East, accumulating snow, generally less than 6 inches, will fall in parts of southern New England and the Lower Hudson Valley, including the New York City metro area.
- Ice potential: Some accumulations likely from north, perhaps central Texas to parts of Arkansas, northern Louisiana, Mississippi, northern Alabama, Tennessee into southern Virginia as well as northern and eastern North Carolina. Sleet accumulations may top 1 inch from parts of Arkansas and far northern Louisiana to western Tennessee, far northwest Mississippi, western Kentucky, southeast Virginia and northeast North Carolina.
- Impacts: Roads may become treacherous and locally impassable in the southern Plains and Ozarks Wednesday and in the Mid-South and parts of the Ohio Valley by later Wednesday. Lingering icy roads are likely into Thursday in ice-affected areas. Power outages and downed tree limbs are possible in areas where freezing rain is most persistent.
