The skies will be clear to partly cloudy overnight and it will still be rather uncomfortable with low temperatures between 73 and 78 degrees. The heat warnings will continue until 7am for Milwaukee and 2pm on Saturday for counties south of the city. The timing of a cold front's passage is key for how hot we get on Saturday. It's possible readings could rise quickly into the upper-eighties across parts of the southwest viewing area before relief arrives later in the day. Sunday looks much more seasonal with plenty of sunshine. There are no widespread storms in the picture, only isolated showers or thunderstorms on Saturday afternoon.
