Definitely a change has returned with temperatures struggling to climb above freezing in the TN Valley and stuck into the 20s up into the mid-Mississippi Valley. The next change will be the return of winter precipitation Monday-Tuesday.
Along and north of the Ohio River, the precipitation will be in the form of snow. Further south, a wintry mix and finally just cold rain is anticipated. Could be a bit interesting for a period of time in portions of the TN Valley, Monday night into Tuesday morning, as precipitation could begin as snow transitioning to all rain with some icing possible, too. At this point, still too far out to nail down the specifics but something to monitor.
Right now, appears the heaviest snowfall will streak out from the Ozarks into western Kentucky with 2" to 4" possible. Further north, up to the I-70 corridor, the snowfall will be lighter, generally 1" to 2"
