Clear skies will prevail for much of the night before a few clouds roll in very late. With dew points very low, our air will feel quite comfortable. A cool front approaches Southeast Wisconsin Tuesday afternoon bringing a threat for showers, but with such little moisture any showers or thundershowers will be few and far between. The biggest change will be in wind direction. Most of Tuesday will have a Southwest breeze changing to a light Northwest breeze by the evening under partly cloudy skies. This will trigger cooler temperatures on Wednesday and for the remainder of the week. The best opportunity for rain occurs on Thursday in Milwaukee.
