Skies will be mostly clear tonight and the winds calm down but temperatures stay warm, in the mid-70s with increasing humidity by the dawn hours. Mid to upper-nineties move in for Thursday and along with dew points in the sixties to low-seventies it will feel much more uncomfortable. There is a heat advisory posted for all of southern Wisconsin that starts at noon and ends at 8 pm in the evening. A weak cold front shifts our winds to the north late in the day and that cold front could touch off a few scattered showers or thunderstorms. Friday will be a little less humiod but still rather warm, with high temperatures in the upper-eighties.
