Forecast issued Tuesday, January 31, 2023
Special Note
A winter weather adivisory is in effect from 6:00 pm tonight to 11:00 a.m. Wednesday. Freezing rain may not begin until closer to midnight, but the NWS is right to err on the side of caution and begin the advisory at 6:00 pm. The main threat from ice will be to roads. Travel troubles are likely areawide Wednesday morning. Please stay tuned for updates.
Ice accumulation is expected to range from 1/10 (0.10) of an inch to 2/10 (0.2) of an inch across the area, with the higher amounts found across northern Cumberland County and Fentress County. The minimal criteria for ice storm conditions is 0.25 inches of ice. While we are not expected to reach that criteria, under the “worst case scenario” some isolated locations (especially across northern Fentress County) could get close to meeting that minimal criteria.
Wednesday night will be a close call, with temps flirting with the freezing mark as rain falls. Stay tuned for updates to that forecast, just in case temps trend just a bit colder.

Radar Model
This radar model runs from 9:00 a.m. this morning to 9:00 a.m. Wednesday morning. The trend is for rain to transition to freezing rain overnight. Amounts will be light, but enough to cause travel troubles.
Weather Summary
Today, rain chances increase and, as temps fall after sunset, the rain will begin mixing with and changing to light freezing rain and sleet across the area. This wintry precip will lead to the potential for hazardous roads across the area tonight and Wednesday morning. Total ice accumulations are expected to stay in the tenth to two tenths range. This is not enough to qualify for ice storm conditions, though isolated locations, especially in Fentress County, could get close to reaching the 1/4 inch criteria for minimal ice storm conditions. If temps trend colder and moisture trends upward, more ice could accumulate.
The emphasis continues to be on the impacts to roadways. The ice that accumulates tonight is not expected to be enough to cause disruptions to the power grid or lead to tree damage.
Rain continues Wednesday night but temps should stay above freezing, though it will be a close call. That rain moves out on Thursday but could end as some snow flurries or snow showers Thursday night.
Stay tuned for forecast updates.
