Increasing clouds tonight with spotty showers moving in from the west late tonight as a cold front approaches on Sunday. The best chance for rain comes in the morning hours, though some spotty showers are still possible throughout the afternoon and early evening hours. The driest times on Sunday will be midday and after 6pm when skies will start to part from mainly cloudy. Highs will be in the upper 70s for most with a few spots hitting 80 degrees with a southwest wind, rain totals will generally be less than a quarter of an inch.
Monday starts out dry but a very saturated storm system from the southwest rolls in by the afternoon hours, this will start the chance for rain and downpours with an occasional thunderstorm. Due to the increasing cloud cover and northeasterly wind, highs will be mainly in the 70s. The heaviest rain falls Monday evening and night with some locations picking up more than an inch of water by Tuesday morning when the showers exit southeastern Wisconsin. Skies will be clearing in the afternoon with highs in the mid-70s. High pressure gives us sunshine for the rest of the work week with the coolest day, temps in the low 70s, on Wednesday. We'll reach 80 degrees again by Friday and the weekend which will start off with storm chances again.
