Some more classic autumn weather is finally arriving with a
reasonably strong low pressure system for the weekend.
Friday and Saturday will be mild with a moderate south or
southwest breeze. Friday will stay dry in Southern Michigan
and afternoon RH will probably drop below 40 percent. Then
occasional rain showers and perhaps a thunderstorm will
develop for Saturday and Sunday. Sunday has a chance to be
quite windy but this may happen after a soaking rain.
