Over the weekend, low pressure will develop in the Mississippi River Valley pulling in moisture and more seasonable air ahead of it. As it progresses toward the Northeast U.S. on Sunday, a very strong cold front will barrel through East Tennessee changing rain to snow and causing temperatures to drop sharply.
At this time, we are expecting 2"-3" of snow in the Knoxville area on Sunday night. Monday morning temperatures will be in the teens and will continue to drop through the day. In fact, temperatures could be in the single digits by Monday afternoon with strong northwest winds creating wind chills below zero. Monday night looks like it will be the coldest night with temperatures possibly dipping below zero in Knoxville. Several models are indicating surface temperatures dropping to between 0°F and -5°F which would be a record low temperature for January 7. The current record low is 6°F set in 1970. After an extremely cold morning, highs on Tuesday may only make it into the mid teens. It appears that Knoxville could experience a period of 60 hours below freezing between Sunday night and Wednesday.
Remember that this is dangerous, extreme cold weather. Please take action to protect pets and animals by finding warm shelter for them. Also, protect any exposed pipes and ensure proper insulation around your home. If you have elderly family members or neighbors, it would also be good to check on them and help them through this extreme cold period.
