Ohio, Indiana, Michigan, Pennsylvania, New York Brace for Dangerous Cold, Lake-Effect Snow, and Below-Normal Temperatures Through Thursday

UNITED STATES — A prolonged stretch of dangerous winter weather is gripping large portions of the Midwest and Northeast as extreme cold, persistent lake-effect snow, and well-below-normal temperatures continue through at least Thursday, according to the latest national weather outlook.

Weather data shows lingering lake-effect snow bands east of the Great Lakes, combined with entrenched Arctic air, keeping conditions hazardous for travel, outdoor exposure, and infrastructure across multiple states.

Lake-Effect Snow Continues East of the Great Lakes

Heavy lake-effect snow bands are expected to persist Wednesday and Thursday across areas downwind of the Great Lakes, including:

• Northern and central Indiana
• Northern Ohio
• Western and central Michigan
• Northwestern Pennsylvania
• Western and upstate New York

These snow bands may shift and redevelop repeatedly, producing localized but intense snowfall rates that can quickly reduce visibility and make roads treacherous, even where surrounding areas see little accumulation.

Much Below Normal Temperatures Hold Firm

Behind the snow, Arctic air remains firmly in place across the Midwest and Northeast. Forecast guidance shows temperatures staying well below seasonal averages through Thursday, preventing snowmelt and allowing icy conditions to persist.

Daytime highs in many areas may struggle to rise above freezing, while overnight lows remain bitterly cold, increasing the risk of refreezing on untreated surfaces.

Pacific Northwest Faces Separate Winter Impacts

While the Midwest and Northeast remain locked in cold, a weak atmospheric river is impacting the Pacific Northwest, bringing:

• Periods of gusty winds
• Rain at lower elevations
• Mountain snow in higher terrain

This system is not expected to bring extreme cold but may still cause travel issues in mountain passes and areas prone to runoff.

Why This Pattern Matters

The national weather pattern shows cold air dominating much of the central and eastern United States, while repeated systems reinforce winter conditions rather than allowing a thaw. With cold persisting:

• Snow remains powdery and slow to melt
• Ice hazards increase during overnight hours
• Travel disruptions remain possible even without major storms

What Residents Should Prepare For

Across affected states, residents should be prepared for:

• Sudden whiteout conditions near lake-effect snow bands
• Icy roads, especially during early morning and nighttime hours
• Prolonged cold exposure risks, including frostbite and hypothermia
• Higher heating demand and continued strain on infrastructure

Officials urge limiting unnecessary travel during snow band activity and taking extra precautions when outdoors.
