Overview

• Sunday and Labor Day feature mostly sunny skies with inland highs in the upper 70s and cooler lakeshore readings in the low to mid-70s due to a lake breeze.
• Holiday travel on Monday looks favorable with light winds, dry conditions and ample sunshine.
• A strong cold front on Wednesday has uncertain timing that would keep highs in the 70s if it arrives early or allow low 80s and a higher storm chance if it arrives later.
• Temperatures are forecast to tumble after the front, with highs falling into the 50s and 60s by Thursday and morning lows dipping into the 40s outside the city late week.
• Meteorologists describe the late-week cooldown as unusually early for September with the potential to challenge daily records for lowest maximum temperatures.
