A major winter system is forecast to sweep across the U.S. from Thanksgiving night through the weekend, followed by a surge of Arctic air that will plunge temperatures well below normal. This dual weather threat is poised to cause significant disruptions for U.S. agriculture - particularly in the Midwest, Northern Plains, and Great Lakes regions - during one of the busiest travel and logistics periods of the year.

The storm will unfold in two waves. The first will arrive Thursday night, Nov. 28, with heavy snow stretching from Montana through the Dakotas into Iowa and the Upper Midwest. The second, more widespread wave will hit Friday night and push across the Central and Southern Plains, bringing a mix of snow, sleet, rain, and strong winds across the eastern U.S. by Saturday and Sunday.

Forecast models indicate 6 inches or more of snow are likely from Iowa through Michigan, with some localized totals near a foot in areas where the two storm systems converge. Additional lake-enhanced snow could drive double-digit totals in parts of Michigan and Wisconsin. In the Southern Plains and Southeast, thunderstorms and moderate rain could affect areas from Texas to Tennessee, including recent storm-hit regions.

Of particular concern for agriculture is the combination of snow accumulation, ice, and 30-50 mph wind gusts, which could lead to blizzard-like conditions, blowing snow, and hazardous travel on major freight and transport routes. As this unfolds, ag input and commodity transport could be delayed, affecting grain shipments, fertilizer deliveries, and feed logistics.

Once the storm system clears, Arctic air will sweep in, dropping temperatures 10-20°F below average through the first week of December. In parts of the Northern Plains, lows may fall below zero, while highs in the Midwest and Ohio Valley may remain below freezing. Areas with deep snowpack will feel the coldest effects.

These conditions create multiple pain points for ag professionals. Livestock producers may face delays in feed deliveries, just as extreme cold raises energy costs and animal stress. Grain haulers and cooperatives could see schedule interruptions, raising costs and pushing some farms to store grain longer than expected. Young winter wheat and cover crops might suffer freeze damage if not yet fully established, potentially affecting spring yields.

Meanwhile, crop insurance inspections, compliance deadlines, and year-end audits may be postponed or disrupted, slowing payments and complicating farm financial planning. Even commodity prices could see short-term impacts if regional grain deliveries tighten unexpectedly.

Farmers, ranchers, and ag logistics operators are urged to prepare now - securing fuel, feed, and storage space ahead of the storm, adjusting shipment schedules, and alerting co-ops or clients to potential changes. As the busiest logistics weekend of the year unfolds under a harsh weather regime, adaptability and preparation will be key to minimizing the storm's impact on U.S. agriculture.
