Low pressure aloft that is cut-off from the westerlies is slowly meandering northward from the Ohio River Valley.
The influence of this low will be quite evident on Tuesday, but less evident by Wednesday and Thursday.
Tuesday looks cool with mainly just rain showers, and a rumble of thunder along the I-69 corridor.
As the low weakens and slowly lifts to the northeast, our temperatures will warm-up and we'll gradually see more sunshine.
However, scattered showers and storms will still be possible during the heating of the afternoon on Wednesday and Thursday.
