An ice storm dumped a messy mix of precipitation onto the area Tuesday night, coating trees, cars and power lines with ice.
"It's been a night of freezing rain and sleet for most of the area," WKYT Chief Meteorologist Chris Bailey said.
He said some areas could get up to three-quarters of an inch of ice. Areas north of Interstate 64 were expected to get the heaviest buildup. Bailey said road conditions were not the primary concern.
"It's going to be the power, and it's going to be the trees and limbs," he said.
Kentucky Utilities reported scattered outages throughout Lexington toward midnight Tuesday.
There were increasing reports of downed trees and limbs, and standing water on roads was becoming a problem in some places.
Bailey said the Lexington area could expect snow showers off and on throughout the day Wednesday, with highs of around 30 early in the day and temperatures falling into the 20s during the afternoon.
"It's going to be really cold the rest of the week," he said, noting that another snowstorm could arrive over the weekend.
While most of Lexington's precipitation fell as rain early in the evening, roads were getting slushy and a thin layer of ice was coating cars and other surfaces by 8 p.m.
Drive-through customers at the Fazoli's on Richmond Road were asked to pull around to the window to place their orders — the speaker outside had frozen over.
Areas to the south of Lexington were primarily getting rain, although Bailey said a wintry mix had been reported as far south as Berea.
Bailey said some people in Madison County also reported thunder and lightning during the icy precipitation.
The state police posts in Elizabethtown and Campbellsburg reported that the slushy roads had resulted in several wrecks.
The state Transportation Cabinet urged people to stay off the roads if possible.
Crews were working past normal hours to treat the roads, and state contractors reported Tuesday night to supplement state crews, according to a news release.
City officials said crews from the city's Division of Streets and Roads and Division of Water Quality would continue to work around the clock and monitor the weather.
