A cold front is forecast to slide east across the region this afternoon and tonight. This feature will interact with a weak upper level disturbance as well as moist air flowing into the region from the south to produce showers and thunderstorms. Some of the storms may become severe, mainly south of a Lone Rock to Sheboygan line, as the cold front moves east into the region. Large hail and damaging winds would be the main hazards, especially across far southern Wisconsin, closer to the surface warm front which will be situated across northern Illinois. The most unstable conditions will be found here. Heavy rainfall is also possible across the area. The heavy rains received this morning have increased soil moisture, which means flash flooding is more likely to become a concern.
