Temperatures will warm into the upper 40’s/lower 50’s ahead of a very potent arctic front later this weekend. Rain chances increase as the front nears during the day on Sunday. The cold front will be very noticeable. A strong northwesterly wind will draw much colder air into the Tennessee Valley late Sunday and early Monday. Precipitation should end in snowfall area wide Sunday Night and early Monday.
At this time, accumulations are possible, however, there will not be much moisture left for a more significant snowfall event as dry air moves very quickly into the region. About an inch or two of snow is expected with the highest amounts over the Cumberland Plateau. Road conditions are expected to decline Sunday evening and become hazardous overnight into Monday.
Monday looks COLD! High temperatures will not get out of the teens. In fact, Temperatures may linger in the lower to middle teens through afternoon. We are going with a high of 14 degrees, however, this may be a bit too warm given the magnitude of the cold surge and heft snowpack upstream.
Monday night looks to be the coldest night we’ve seen since before the start of the millennium. We are expecting lows to be around 0 for most and below 0 for some. Wind chill values are going to be in the dangerous category (between -15F and -5F). The record low temperature for Tuesday is 9 degree in Chattanooga. That record will be in serious jeopardy.
Don’t wait for the cold weather to get here! Now is the time to prepare for an unprecedented and potentially dangerous arctic blast. Make sure you shutoff water to outdoor faucets. Also, it may be a good idea to let a stream of water flow through your indoor faucets (a narrow stream will do) to prevent pipes from freezing. Exposure to outdoor animals could result in death if action is not taken. Please plan ahead in order to mitigate for this potential.
Additionally, make sure your vehicle is winterized and has a full tank of gas. Stay with MarionCountyMessenger.com for the latest on this developing weather situation.Meteorologist: Robert Frye Updated: 1/4/2014 at 1:30pm
