Cold air is here, but it didn't arrive in time to equal widespread travel impacts and accumulating snow.
For days on end, our forecast data has been consistently in agreement on accumulating snow in the Tennessee Valley. Even as of midnight, data sources were offering solutions of 1 to 2 inches of snow along and east of I-65. By 2 AM, some rain across higher elevations was turning to snow. However, it was becoming clearer that this was a winter weather event that the data sources (i.e. computer models) we so heavily rely upon weren't handling the system well.
At least, in regard to the snow forecast. Cold air has been arriving more slowly, and while wind chills are indeed in the teens, the delay of the cold air is exactly what caused our snow forecast to bust. Now we can focus on the what's to come.
The remainder of Tuesday will be cold and windy with highs only reaching the mid 30s. Wind chill values linger in the teens and lower 20s through the day. Expect similarly cold temperatures Wednesday before we plummet into the mid teens by early Thursday morning.
