Overview

• Saturday starts cloudy and mostly dry with only a slight chance of sprinkles before sunshine breaks out and highs reach the low to mid-70s, a bit below the seasonal average near 81 degrees.
• Sunday and Labor Day trend mostly sunny with highs in the upper 70s to around 80, offering favorable conditions for outdoor plans and travel.
• Easterly winds off Lake Michigan will keep the shoreline cooler than inland neighborhoods through the holiday period.
• A cold front is projected to arrive Wednesday with roughly a 60% chance of showers and possible thunderstorms, and timing could determine whether highs reach the 70s or briefly the low 80s before the front passes.
• Temperatures turn sharply cooler after the front, with highs falling into the 60s late week; NBC meteorologists note some spots could see upper-50s highs Thursday and morning lows dipping into the 40s later in the week.
