4th of July Preview

The weather in the days leading up the 4th of July could be rather unsettled. Warm and more humid air is expected to begin flowing into the region by Sunday, with high temperatures in the upper 80s to lower 90s forecast for Monday thru Wednesday. Also, this developing pattern will favor the development of mesoscale convective complexes (a big complex of thunderstorms) somewhere in the northern Plains, and these complexes could then move east and southeast toward Wisconsin. Usually, with this type of pattern, rain and thunderstorms are more likely locally during the overnight and early morning hours, with the daytime hours usually remaining dry, but very warm. These complexes can also be severe sometimes. It will be nearly impossible to pinpoint the timing of these expected storms until about a day before the event, unfortunately.
