Refreshing night ahead, humidity returns this weekend

 It was a much more comfortable day in the Stateline Friday compared to the last several hot and humid days from the past week. Five of the last six days have featured highs at least 90° in Rockford. But Friday only reached 85°, the coolest daytime high since last Friday.

Late into the evening, temperatures will continue to drop following this morning's cold front. It will be a refreshing night, with overnight lows in the low 60s and even pushing upper 50s in some spots. With high pressure overhead, we will clear out overnight. We may see some patches of fog, especially in areas that saw heavy rain over the last few days.

Unfortunately, the relief from the heat and humidity is short-lived, as we see a return this weekend. Dew points will rise back near and above 70° through Sunday, pushing heat indices into the 90s Saturday and near 100° Sunday. Air temperature will reach the upper 80s Saturday and low 90s Sunday.

Much of the weekend will be dry, but there is a slim chance for stray thunderstorm or two across Southern Wisconsin Saturday afternoon and evening. Locally better chance for storms will arrive Sunday afternoon and evening, potentially lasting into Monday. Storm coverage will remain scattered, with the strongest storms possibly producing damaging winds and heavy rain.
