A slow buildup in heat, humidity plus rain, storm chances

MILWAUKEE (CBS 58)--Enjoy the dry, seasonably cool weather while it's here because more unsettled changes are coming by the end of the week.  In fact, we could see a few showers late Tuesday into early Wednesday with an upper air feature.  Then stronger low pressure begins to move into the area from the southwest.  This will trigger showers and storms on and off Thursday and Friday.  And then it looks like showers, widely scattered, will linger through the weekend.  But there will be plenty of dry hours as well.  Temps will be fairly seasonable during the weekend.
