Editor's Note: This entry was updated at 12:50p et to reflect the Storm Prediction Center's outlook update, which now includes a portion of "high risk" severe weather across portions of Georgia and South Carolina Wednesday.
Another round of severe weather is possible for North Carolina and South Carolina Wednesday - and this one could be even more powerful than Monday's storms.
We are watching another cold front moving into the region from the west. This will be a strong cold front, leaving behind brisk, winter-like temperatures - - but that's after the storms.
A warm front moved into western Carolinas Wednesday morning. That helped 'prime' the atmosphere, bringing in very warm and moist air; both are key features for severe weather formation. Portions of South Carolina and western North Carolina began to see non-severe thunderstorms by lunchtime.
Early Wednesday afternoon, the National Weather Service's Storm Prediction Center issued a rare "High Risk" for severe weather across portions of South Carolina and Georgia. This is the highest possible level on their severe weather outlook. Widespread severe weather is expected in those areas, which include parts of the South Carolina midlands including the Columbia and greater Augusta metro regions. Tornadoes and widespread damaging winds are likely.
The first round of severe weather Wednesday will arrive in the form of individual cells. While scattered, they tend to feature more "super cell" structures. This is when the tornado threat will be the highest. Most of the Carolinas can expected to see these cells between 4-8 pm.
Then the actual line of storms will move into the area between 8 pm - 2 am. This line would provide some heavy rain, and possibly damaging wind. We will also monitor any kinks in the line of thunderstorms. Those areas would provide the opportunity for an isolated tornado or two.
Those areas of South Carolina not in the "High Risk" are placed under a "Moderate Risk," which is the Storm Prediction Center's second highest tier. Those areas include Greenville, Spartanburg, Myrtle Beach and Charleston.
All of North Carolina is now in an "Enhanced Risk," the Storm Prediction Center's third of five tiers. The metro areas in this threat include, but are not limited to, Charlotte, Raleigh, Greensboro, Fayetteville, and Wilmington.
While not everyone in the Carolinas will see tornadoes, we will all need to monitor for damaging winds. Strong winds can damage property and bring down power lines.
Once the front moves through the region, we will see northwest winds. This will actually provide a decent snow event for the mountains. It looks like they could receive a coating of snow.
It is quite the active pattern setting up for the region. We hope you will stay with the Carolina Weather Group, the National Weather Service, your local broadcasters and your community emergency managers for important updates. The Carolina Weather Group will be dedicating our regular Wednesday night podcast episode to the day's severe weather. Join us live at 8p et for coverage on YouTube or Facebook Live.
