Iowa–Illinois — Snowflakes drift sideways in the bitter air, catching headlights and coating dark pavement before crews can keep up. Winter conditions are actively developing across the Quad Cities this morning, with snow spreading through eastern Iowa and northwest Illinois.
Light accumulating snow is expected through today and into the evening. Most locations will see 0.5 to 1 inch, while parts of northeast Iowa could reach up to 2 inches. Temperatures stay locked below freezing, which means nearly all snowfall sticks immediately.
As snowfall tapers later today, colder air settles in. That sets the stage for spotty freezing drizzle tonight, especially on untreated roads, bridges, and sidewalks. Even a thin glaze can create dangerous driving conditions. Travel along I-80, I-74, and local river crossings may become slick quickly.
Winds remain light, but visibility may briefly drop during steadier snow bursts. Drivers should slow down, increase following distance, and plan extra time through the afternoon and evening commute. Pedestrians should watch for icy patches that blend into slushy snow.
By Monday, skies brighten and snow ends. Highs climb near 31 degrees, offering limited melting. Any moisture left behind may refreeze after sunset, renewing flash-freeze risks. Tuesday and Wednesday stay dry but cold, with highs near 30 and lows in the teens.
Looking ahead to midweek, temperatures gradually moderate. Sunshine increases, and by Thursday highs approach 40 degrees. That warmth is brief. February remains active, and meteorologists continue monitoring broader Midwest patterns tied to deep cold over the Great Lakes.
For now, winter driving rules apply. Keep emergency supplies handy and avoid sudden braking on slick surfaces. Conditions may change quickly as snow transitions to ice.
