Overview

• Sunday brings a noticeable cooldown behind the Saturday night front, with highs in the low to mid-70s around Chicago and only the upper 50s to mid-60s in parts of Michigan.
• Lake-effect rain showers develop Sunday into Monday, most persistent near Lakes Michigan and Superior, while inland Northeast Ohio faces only spotty precipitation.
• North to northwest winds strengthen in lake-influenced areas, with gusts up to 20–35 mph in the Upper Peninsula and along Lake Superior.
• Beach Hazards Statements and small craft concerns are in effect for Lake Michigan, with 3–6 foot waves and dangerous currents in northwest Indiana and potential waterspouts over open waters.
• Overnight lows may dip into the upper 40s in sheltered spots early this week before a gradual warm-up pushes temperatures closer to seasonal norms later in the week.
