Scattered areas of showers and t'storms will be ongoing across the state Saturday morning, as a warm front quickly lifts northward across the state.

Along and south of the warm front, a favorable environment will be in place, with low instability, good moisture, great forcing and great shear expected. Scattered showers and t'storms are expected to develop along a dry line, which is expected to be in the vicinity of the Mississippi River by early to mid afternoon.
