(WHAS11) -- A potentially very large snow-maker is working its way to the Ohio Valley and by Wednesday a large part of the WHAS11 viewing area could see significant snowfall.
The north and west counties in our viewing area currently in a Winter Storm Warning will see rain turn to a wintry mix of freezing rain and sleet tonight. Around 3:00 Wednesday morning, a transition to snow is expected. Heavy snow could last through Wednesday afternoon. Depending on your exact location, the hardest hit areas will see between four and nine inches of snow. This will be mainly the counties of Jackson, Jennings, Lawrence, Dubois, Orange, Washington and Scott. There is also a threat for light ice accumulations.
For the area currently in a Winter Storm Watch (Jefferson, Crawford, Perry, Harrison, Floyd, Clark and Trimble Counties in Indiana) accumulation of three to six inches is possible through Wednesday evening.
For Metro Louisville, we're expect one to three inches of snow. The rest of the area will see about an inch.
There is still a lot of uncertainty to this system. A shift to the north or south slightly can influence snow totals greatly.
This storm is part of a large system, threatening to bring snow, thunderstorms and tornadoes to a large portion of the country on Christmas and Wednesday. It could create travel problems for a large part of the United States.
WHAS11's Good Morning Kentuckiana will be on the air early Wednesday morning monitoring the snowfall, ice, rain and what it means for road conditions.
