Update, 6:45 p.m.: Crews have made progress clearing thoroughfares and main routes, but many side roads and neighborhood streets still remain covered in ice and snow, according to a county news release.

More snow, an anticipated wintery mix of snow and rain combined with bitterly cold temperatures tonight and Thursday morning led city and county mayors to urge residents to stay home and off the roadways.

“It’s been several years since we’ve been hit this hard with harsh winter weather,” Montgomery County Mayor Durrett said. “Fortunately this does not happen often. It’s important to exercise caution when it does happen.”

“Although the road crews have worked diligently and will continue clearing roads, we still have black ice on the roads and in parking lots where citizens use services,” City Mayor Joe Pitts said.

Update, 3 p.m.: Montgomery and surrounding counties are now under a Winter Storm Warning, which has been moved three hours earlier. It remains in effect through 6 p.m. Thursday.

Update, 12:10 p.m.: A Winter Storm Warning is now in effect for Trigg, Todd, Lyon, Christian and Caldwell counties in Kentucky, lasting through 6 p.m. Thursday. The National Weather Service in Paducah, Kentucky, predicts 2 to 5 inches of snow for the Kentucky counties.
