As the final days of November give way to early December, U.S. agriculture straddles a familiar transition: shorter days, larger day–night temperature swings, and periodic fronts that shuffle moisture and cold air across the country. Below is a region-by-region synthesis of the past 24 hours’ agricultural weather themes and a planning-oriented outlook for the next seven days. Conditions can vary sharply over short distances in late fall, so growers should pair this guidance with trusted local forecasts and on-farm observations.
Last 24 Hours: Agricultural Takeaways by Region
Northern/Western Corn Belt (Dakotas, Minnesota, Iowa, Nebraska)
- Seasonally cold mornings with subfreezing starts in many areas, supporting continued soil surface firming for late fieldwork where soils are not saturated.
- Patchy light wintry precipitation possible in the northern tier and around the Great Lakes; travel and livestock exposure management remain priorities during early and late-day temperature minima.
- Winds have periodically been brisk, elevating livestock wind-chill stress and modestly improving surface drying where soils allow.
Eastern Corn Belt (Illinois, Indiana, Ohio, Michigan, Wisconsin)
- Intermittent light showers or flurries near the lakes; elsewhere, dry to partly cloudy with cool temperatures supportive of post-harvest grain aeration.
- Residual dampness in low-lying fields; rutted areas from earlier wet periods remain slow to firm.
Central & Southern Plains (Kansas, Oklahoma, Texas Panhandle)
- Cool, breezy stretches promoting evapotranspiration that is low overall but enough to slowly firm the topsoil.
- Winter wheat stands generally benefitting from cool temperatures; exposed stands remain sensitive to abrupt freezes where snow cover is absent.
Delta & Mid-South (Arkansas, Mississippi, Louisiana, Tennessee)
- Periodic light showers possible along and ahead of passing fronts, but many locations experienced workable conditions between waves.
- Cooler nights improving storage conditions; watch for morning fog pockets reducing visibility for hauling.
Southeast (Gulf Coast to Carolinas)
- Humidity higher near the Gulf and Atlantic coasts with scattered showers in spots; inland areas mainly dry and seasonably cool.
- Citrus, winter vegetables, and nurseries continue routine cold protection; frost pockets possible in interior/rural zones.
Central Valley & Southwest (California, Arizona, New Mexico)
- California’s interior valleys faced cool, stable air with patchy tule fog; daytime warming limited where fog persisted.
- Southwest largely dry; irrigation demand remains low but persistent in leafy greens and winter vegetables.
Pacific Northwest (Washington, Oregon, Idaho)
- Onshore flow episodes favored clouds, light rain at lower elevations, and mountain snow; rangeland and winter wheat areas experienced chilly, damp conditions.
- Snowpack building gradually at elevation, supporting early-season water supply outlooks.
Northern Rockies/High Plains
- Cold mornings and periodic light snow in wind-favored corridors; livestock cold stress elevated during overnight and dawn hours.
Northeast
- Seasonable late-fall mix: scattered light rain/snow showers, more frequent downwind of the Great Lakes; otherwise cool and breezy.
- Short fieldwork windows favored tasks like equipment maintenance and grain movement rather than soil disturbance.
Seven-Day Planning Outlook (Regional, Risk-Based Guidance)
Early December typically brings fast-moving fronts, brief warmups ahead of systems, and quick cool-downs behind them. The guidance below emphasizes operational risks and likely windows rather than pinpoint totals.
Northern/Western Corn Belt
- Temperatures: Generally below normal at night with periodic daytime moderation; watch for repeated freezes each morning.
- Precipitation: Light, frequent chances of snow flurries or mixed precipitation near the Dakotas/Minnesota/Wisconsin and Great Lakes; minimal liquid accumulation elsewhere.
- Fieldwork: Short, usable afternoon windows on drier ground; rutted or poorly drained fields remain slow to improve.
- Livestock: Maintain windbreaks; watch stock water supplies for icing.
Eastern Corn Belt
- Temperatures: Cool with recurring frosts; a day or two of milder air may slip in ahead of a midweek front, then cooler again late week.
- Precipitation: Light rain/snow chances tied to frontal passages; lake-effect bands locally stronger downwind of Lakes Michigan and Erie.
- Fieldwork: Limited; best windows tend to cluster in the midday/early afternoon between fronts.
- Storage: Favorable for grain aeration on cool, dry days; monitor condensation during intra-week warmups.
Central & Southern Plains
- Temperatures: Swingy—cool starts, periodically mild afternoons; brief cold snaps likely behind fronts.
- Precipitation: Generally light and scattered with frontal passages; many locations stay mostly dry.
- Winter Wheat: Good hardening conditions; newly emerged stands remain sensitive to exposed freezes and desiccating winds—retain some surface residue where possible.
- Fieldwork: Multiple workable days; wind may be the bigger limiter than wetness.
Delta & Mid-South
- Temperatures: Seasonable to slightly cool; a modest warm surge ahead of a midweek front, then cooler behind it.
- Precipitation: One to two frontal rain opportunities; heaviest totals near the Lower Mississippi corridor if a Gulf feed accompanies the front.
- Fieldwork: Schedule hauling and maintenance early week and immediately after frontal passage; brief ponding possible in heavier showers.
Southeast
- Temperatures: Mild days along the coasts, cool inland nights with patchy frost in rural lows; colder behind late-week fronts.
- Precipitation: Scattered showers and a few thunderstorms with frontal pushes; coastal zones favored over interior on totals.
- Specialty Crops: Prepare frost protection for interior citrus/vegetables for one or two nights following frontal passage.
Central Valley & Southwest
- Temperatures: Cool nights; periodic valley fog in California curbing daytime highs where it lingers.
- Precipitation: Limited for most valley and desert zones; light coastal or orographic precipitation possible if a weak Pacific disturbance brushes the region.
- Irrigation: Low demand persists; monitor soil temperature and moisture for winter vegetables to avoid overwatering in cool soils.
Pacific Northwest
- Temperatures: Chilly, especially overnight; daytime highs moderated near the coast.
- Precipitation: Periodic light to moderate rain episodes in lowlands with accumulating mountain snow as systems traverse the region.
- Operations: Windows for field access remain narrow; protect livestock from wet cold and provide dry pads.
Northern Rockies/High Plains
- Temperatures: Cold to very cold mornings; periodic reinforcing shots of Arctic air possible late week.
- Precipitation: Light, mainly snow with localized blowing/drifting during windy spells.
- Livestock: Prioritize wind shelter and energy-dense feed; monitor calves and late-gestation stock.
Northeast
- Temperatures: Cool overall with notable chill behind each frontal passage; occasional brief moderation.
- Precipitation: Light mixed precipitation events; higher elevations favored for snow, coastal plain more rain.
- Operations: Focus on storage, hauling, and equipment service between systems; allow extra time for rural road safety during slick morning periods.
Frost, Freeze, and Wind Risk
- Frost/Freeze: Nighttime freezes are likely on multiple nights across the Northern Plains, Upper Midwest, and interior Northeast; patchy frost reaches interior Southeast valleys following frontal passages.
- Wind: Breezy conditions accompany fronts across the Plains and Great Lakes; wind-chill impacts notable for outdoor labor and livestock care.
Soil Moisture and Fieldwork Windows
- Drier windows: Central/Southern Plains, portions of the Southwest, and interior California will see the most consistent field access.
- Intermittent delays: Pacific Northwest lowlands, northern Great Lakes belts, and Delta/Southeast near frontal rainfall will have shorter work windows.
- Drying pattern: Low sun angle limits drying rates everywhere; wind-driven surface drying helps in open Plains but increases erosion risk on bare fields.
Irrigation, Fertility, and Pest Considerations
- Irrigation: Minimal across most row-crop areas; continue light, targeted sets for winter vegetables and leafy greens in the Southwest and Florida as needed.
- Nutrients: Cool soils slow mineralization; time applications during drier windows to reduce runoff risk ahead of fronts.
- Disease/Pests: Cool, damp intervals favor foliar diseases in winter greens (PNW, Southeast) and storage molds if grain is not adequately cooled/aerated.
Operational Planning Tips for the Week Ahead
- Schedule: Target midday/afternoon slots for any field access in cooler regions; reserve early and late-day hours for livestock checks and frost/freeze protection.
- Logistics: Plan hauling around frontal timing to avoid slick roads and fog, especially in interior valleys and near the Great Lakes.
- Protection: Maintain windbreaks, ensure reliable water access in freezing conditions, and stage frost cloths/irrigation for Southeast and Southwest specialty crops.
