The chance of tornadoes and other violent storms grew for Charlotte, Rock Hill and Hickory this weekend, with those cities having the “highest chance of severe hazards” in the Western Carolinas on Monday, National Weather Service meteorologists said.

The cities are under an “enhanced risk” of “numerous severe thunderstorms” between 6 and 10 a.m., NWS forecasters said on social media.

“While a few isolated storms could occur ahead of a line of thunderstorms Sunday evening, the main concern is for Monday morning,” NWS meteorologists said.

“Confidence is higher for severe hazards like tornadoes in areas east of the mountains, especially along and east of I-77 and south of I-85,” according to the NWS office in Greer, S.C.

Damaging winds are likely, NWS forecasters said.

“Remember, straight line winds can snap trees, down power lines and cause damage to homes and cars,” the NWS said. “Know where your safe place is and avoid seeking shelter in a mobile home.”

“Our main concern is the line of thunderstorms anywhere from 6 to 10 a.m. Monday,” meteorologist Christiaan Patterson of the Greer office told The Charlotte Observer.

School buses and commuters will be on the roads, she said. It’s important for everyone to know in advance a “safe place” to go during storms and have a way of receiving weather alerts, she said.

Saturday afternoon, the S.C. State Climatology office issued a similar severe weather warning.

“We remain on track for an outbreak of severe thunderstorms on Monday, capable of causing widespread damaging wind, large hail, and tornadoes,” Frank Strait, severe weather liaison for the office said in a statement.

“It still looks like the timing will be early in the day over the Upstate, possibly even before daybreak in the far west, through midday,” Strait said. “The rest of the state will see the storms hit from midday through early evening.”

Thursday, five tornadoes ripped through parts of three Eastern North Carolina counties, injuring a person in a home, tearing roofs, slicing trees and overturning campers, the National Weather Service reported late Friday.

Charlotte has a 100% chance of showers Monday, the NWS forecast on Sunday showed. Sunny skies are forecast on Tuesday and mostly sunny skies through Saturday.

After an expected high of 72 on Sunday, Charlotte could see highs near 66 on Monday, 48 on Tuesday, 50 on Wednesday, 62 on Thursday, 70 on Friday and 75 on Saturday, according to the forecast.
