On Friday, a warm front will be working its way northward to the southern part of Wisconsin that will keep an already unstable atmosphere active as there will be plenty of heavy showers and storms that will already be moving through the northern half of Wisconsin. For the track, scattered to numerous showers and storms will be possible during the morning and into the start of the afternoon hours, but rain chances will drop to a small chance by the mid-afternoon hours. Skies will be mostly cloudy throughout the day, with the afternoon high maxing out in the mid-70s. Rain chances will be around 50% to start the day, but will eventually fall to around 30% by the mid-afternoon hours. Winds will be out of the southeast at 5-15 mph.
The good news is the coverage in the scattered shower and thunderstorm activity will be less on Saturday, even though we'll be in-between a warm front to the north and a cold front to the west. The overall rain chance will be maxed out around 40% mainly during the morning hours, but becoming a little less likely during the afternoon to early evening hours. Skies will be partly cloudy, with afternoon highs topping out in the lower 80s. Winds will be out of the south at 5-10 mph.
The cold front will get closer to the area on Sunday, and it will keep the overall shower and thunderstorm chances around 40%, mainly during the afternoon hours, but we can't rule out a passing shower before that. Skies will be partly cloudy and afternoon highs will max out in the lower 80s. Winds will be out of the southwest at 5-10 mph.
