Nashville, TN – The National Weather Service has issued a winter storm warning for ice and snow which is in effect from noon Friday, February 20th to 9:00am CST Saturday, February 21st for Clarksville-Montgomery County as well as Middle Tennessee.
Accumulations from 1 to 2 inches of snow are expected Friday, followed by one tenth to one half inch of ice in the form of freezing rain Friday evening through early Saturday morning. Areas along and east of Interstate 65 will be the hardest hit with new ice amounts up to one half inch. The east half of Middle Tennessee may later be placed under an ice storm warning.
Going into Friday evening, warm air above the surface will surge across the region, changing snow over to sleet and mostly freezing rain. Significant ice amounts are expected with one tenth to one quarter of an inch of ice over the west half and one quarter to one half inch of new ice for areas east of Interstate 65. This additional ice is likely to cause major problems.
Fortunately, warmer air will continue to move in late in the night with a transition over to liquid rain beginning along the Tennessee River around midnight and moving east to the plateau by 9:00am Saturday. After the change to rain, some heavy rainfall is possible through Saturday with the potential for localized flooding.
Ice and snow will make travel hazardous. Freezing rain will add to ice that is already on trees and other surfaces to cause damage. Tree limbs are likely to fall and power outages are likely.
Major disruptions to travel are expected Friday afternoon through early Saturday morning. Gusty winds will add to the threat for falling limbs and power outages.
Warming temperatures and heavy rainfall will bring the potential for localized flooding on Saturday.
