Periods of wintry precipitation are possible for the mid state through Monday...
A surface low pressure system over southeastern TX will organize and track eastward along the Gulf Coast through Saturday. Moisture will be lifting northward and will be interacting with colder air over middle TN. The first bout of wintry precipitation will occur tonight and early Saturday across northern portions of the area, generally to the north of I-40. A mixture of sleet and snow is expected. However, amounts will be light and little if any accumulation is expected. Further south, the precipitation should fall as rain, primarily.
AdvertisementA better chance of mixed precipitation will occur Saturday night across the northwest third of the mid state as well as far northern areas including the northern Plateau. Rainfall across this area will change to a mixture of freezing rain and sleet. Ice accumulation of less than one tenth of an inch is possible. Further south, the precipitation should fall as rain. The mixed precipitation will continue into early Sunday morning. On Sunday night, our cold air depth will begin to increase as an upper level slug of energy dives southeastward from the mid west. This will bring a chance of some snowfall to the area. Amounts of 1/2 inch to 1 inch will be possible, with the best chance occurring to the east of I-65, and in particular the Cumberland Plateau region. Note that there is still a great deal of uncertainty with this winter weather scenario
