Much Cooler Weekend Ahead

Who's ready for a fall-like weekend? If you enjoyed the heat and humidity, you may not like what we have on tap by Saturday. Friday will be quite humid as we see a return to southwesterly winds. That will usher in higher humidity once again, in addition to keeping our temperatures in the lower 80's. As another cold front approaches and an area of low pressure deepens to our west, there is a risk of isolated showers and storms throughout the afternoon. However, Friday evening and Friday night feature a far better chance of rain and storms. Some of the rainfall could be heavy as another unseasonably moist air mass sits over northern Illinois and southern Wisconsin.

The front passes early Saturday morning, which will keep a threat of showers through lunchtime. As it passes, our winds will turn northwesterly and gust upwards of 20-25 MPH. Those northwesterly winds will usher in much cooler, less humid air. They will also be responsible for keeping mostly cloudy skies in the forecast through the day. In fact, an isolated shower is possible through the afternoon as highs only reach the lower 70's.

Saturday night could feature the coolest air we've seen since May! Models are suggesting upper 40's as skies clear and winds calm, which would allow very efficient cooling to take place. Sunshine returns Sunday as high pressure builds in, but highs again only reach the lower 70's with cooler winds still in place.
