Strong area of low pressure tracks into the Tennessee Valley through the overnight hours into Wednesday. It moves into Ohio then to the northeast late evening. The associated cold front crosses in the very early morning hours of Thursday. Ahead of the front, a surge of milder air moves in, which will allow temperatures to continue to climb into the evening Wednesday. The high for the day takes place just before midnight. We continue to warm into the very early morning hours Thursday, where the high for the day, in the low 50s is expected. Cooler air wraps in behind the departing system. Temperatures will fall through the morning, rebounding only a few degrees in the early afternoon Thursday to the mid 40s, then fall quickly in the evening. Showers and a rumble of thunder likely early Thursday, then later in the day, a few rain or snow showers possible.

High pressure builds in for Friday and Saturday. Colder air will settle in for a couple of days too. High temperatures will run below average in the mid 30s Friday. It will be a very cold morning in the low 20s for Saturday, however, temperatures rebound to seasonable averages in the low 40s under mostly sunny skies. A cold front approaches Sunday, but never moves through. It stays north allowing for milder air to transport in. With sunshine and a few more clouds, highs will jump to the low to mid 50s. Cold front comes through Monday, bringing our next rain threat. Highs will still be mild in the low 50s before colder, drier air returns Tuesday.
