Note for readers: This report provides agriculture-focused weather context for early November based on seasonal norms and common patterns across U.S. farming regions. For site-specific observations from the last 24 hours and precise 7‑day forecasts, consult your local National Weather Service office or extension service. The outlook below is intended to help plan fieldwork, harvest, irrigation, and livestock management between Nov 5 and Nov 12.

National agricultural weather context

Early November is a transition period: polar air masses increasingly dive into the Plains and Midwest, the Pacific Northwest’s cool-season storm track ramps up, the Desert Southwest stays largely dry, and the Southeast/Delta oscillate between mild, humid spells and brief cool-downs behind passing fronts. Frost and freeze risks expand southward and westward with each clear, calm night; wind events are common in the Plains and Intermountain West behind cold fronts; and valley fog becomes a recurring factor in California’s Central Valley when high pressure settles in.

What many farms likely encountered in the last 24 hours

• Northern/Central Plains and Upper Midwest: Seasonable to chilly conditions are typical now, with a chance that a recent front produced scattered light precipitation and brisk northwesterly winds. Spotty frost/freezes are common on clear nights.
• Corn Belt: Passing showers are common with November fronts; many fields may have seen damp surfaces, gusty winds, and cooler air moving in. Cloud cover variability influences daytime drying rates.
• Pacific Northwest: This is peak onset for cool-season rainfall; lowland rain and mountain snow are commonplace, with periodic breezy conditions along and behind fronts.
• California (Central Valley and coastal produce): Generally dry between Pacific systems. Night and early morning valley fog (Tule fog) is increasingly likely on clear, calm nights. Marine layer influences continue on the coast.
• Southwest deserts (AZ, Imperial Valley): Predominantly dry, large diurnal temperature ranges, and occasional breeziness.
• Delta and Mid-South: Variable clouds with a chance of light showers along recent frontal passages; otherwise mild days, cooler nights. Patchy fog possible near waterways.
• Southeast: Mild to warm afternoons with humidity periodicity; scattered showers along fronts or sea-breeze circulations; brief cool-downs behind fronts.
• Northeast: Seasonably cool with passing showers common; higher-elevation frost likely on clearer nights, and breezy intervals with frontal passages.
• Intermountain West/Rockies: Chilly mornings, dry to showery depending on elevation; light mountain snow is common with any recent shortwave passages; downslope winds in favored corridors.

7‑day agriculture-focused outlook (Nov 5–12)

Northern Plains (MT, ND, SD) and Upper Midwest (MN, WI, MI Upper Peninsula)

• Temperatures: Near to below seasonal averages. Repeated frost/freeze risk on clear nights; watch for subfreezing dawns in open, low-lying fields.
• Precipitation: Light, intermittent events with clipper-like systems; rain/snow mix possible north and at elevation. Totals generally modest but enough to intermittently slow field drying.
• Wind: Breezy to windy behind fronts, with reduced spraying windows.
• Fieldwork: Short drying windows between weak systems; schedule harvest and fertilizer applications for sunny, breezy afternoons.
• Management notes: Protect late-grazing water sources from icing; monitor livestock wind chill; consider stabilizing residue to reduce wind erosion on open ground.

Central/Southern Plains (NE, KS, CO plains, OK, TX Panhandle)

• Temperatures: Near seasonal north; slightly above seasonal south. Nighttime frost risk mainly north and west on clear nights.
• Precipitation: One or two frontal passages could bring scattered light rain; snow risk low except in High Plains/foothills with colder intrusions.
• Wind: Frequent post-frontal gusts; fire-weather pockets possible on warm, dry, windy days, especially west.
• Fieldwork: Generally favorable harvest windows, with brief pauses for wind or light precip.
• Management notes: Newly emerged winter wheat benefits from even light moisture; plan herbicide timing around wind and temperature thresholds.

Corn Belt (IA, IL, IN, OH, MO, southern MN/WI, lower MI)

• Temperatures: Near seasonal with cool shots. Frost possible in northern/western zones on clear, calm nights.
• Precipitation: Periodic light to moderate showers with passing fronts; lake-effect showers downwind of the Great Lakes if colder air arrives.
• Wind: Gusty during frontal passages, easing within 24–36 hours.
• Fieldwork: Harvest windows remain, but anticipate stop‑and‑go progress tied to showers and dew persistence.
• Management notes: Grain drying costs may fluctuate with humidity swings; watch lodging potential in fields exposed to gusts.

Delta and Mid-South (AR, MS, LA, western TN/KY)

• Temperatures: Mild days, cooler nights; generally near to slightly above normal.
• Precipitation: Intermittent light showers with fronts; any heavier activity would be localized.
• Wind: Briefly gusty along fronts, otherwise manageable.
• Fieldwork: Good windows for late harvest and fall tillage; monitor for brief, showery disruptions.
• Management notes: Residual soil warmth supports cover crop establishment; scout for disease where leaf wetness persists.

Southeast (AL, GA, FL, Carolinas, southern VA)

• Temperatures: Near to above normal. Limited frost risk inland on the coldest, clearest nights.
• Precipitation: Scattered, mainly along fronts or sea‑breeze; coastal zones wetter than inland.
• Wind: Generally light to moderate; locally breezy with frontal passages and along the coast.
• Fieldwork: Favorable for vegetable harvest and pasture management; brief halts in showery periods.
• Management notes: Disease pressure remains possible in humid pockets; time fungicide applications around dry windows.

Northeast (PA, NY, New England)

• Temperatures: Seasonably cool; frost and light freeze risk widespread inland during clear nights.
• Precipitation: Occasional light to moderate showers; higher-elevation wet snow possible in colder bursts.
• Wind: Breezy after fronts; lake-effect bands possible downwind of the Great Lakes.
• Fieldwork: Narrow, cooler windows; plan for slower drying and shorter daylight.
• Management notes: Protect late-season horticulture from radiational frosts; livestock windbreaks beneficial on breezy, chilly days.

Pacific Northwest (WA, OR, ID)

• Temperatures: Cool; lower snow levels in the Cascades and northern Rockies with colder systems.
• Precipitation: Multiple waves of lowland rain and mountain snow are typical now; soils trend wetter.
• Wind: Periodically breezy along coasts and gaps with frontal passages.
• Fieldwork: Limited dry stretches; prioritize drainage upkeep and schedule operations in shorter breaks between systems.
• Management notes: Monitor feed quality and shelter for livestock in persistent wet/chilly conditions; protect sensitive specialty crops from oversaturation.

California (Central Valley, Central Coast, Salinas, Imperial/San Joaquin)

• Temperatures: Near normal; cool nights inland with increasing fog potential in the Central Valley.
• Precipitation: Mainly dry between systems; light rain possible with any passing fronts, more likely north.
• Wind: Generally light; locally breezy near passes and coastal gaps.
• Fieldwork: Favorable for harvest and field prep; factor in morning delays from fog/low clouds.
• Management notes: Plan irrigation conservatively; adjust harvest schedules for reduced visibility and moisture from fog.

Southwest Deserts (AZ, NM valleys, CA Imperial)

• Temperatures: Mild days, cool nights; large diurnal ranges.
• Precipitation: Low probability; mostly dry.
• Wind: Occasional afternoon breezes; stronger winds possible along and behind any weak fronts.
• Fieldwork: Excellent overall; mind afternoon low humidity for transplant and irrigation timing.
• Management notes: Continue frost monitoring in colder pockets; manage dust and erosion on bare ground during windy spells.

Intermountain West and Rockies (UT, CO high plains/foothills, WY, western MT)

• Temperatures: Cool to seasonably cold; frequent freezes at elevation and in basins.
• Precipitation: Light to moderate mountain snow with passing disturbances; valley rain/snow mix possible.
• Wind: Gap and downslope winds at times; stronger gusts in typical corridors.
• Fieldwork: Short, cool windows; livestock operations take precedence as rangelands transition.
• Management notes: Prepare for slick conditions in early/late-day operations near elevations; secure structures against gusts.

Risk watchlist for Nov 5–12

• Frost/Freeze: High likelihood across the Northern Plains, Upper Midwest, Northeast, Intermountain West; moderate risk in the Central Plains and interior Southeast on the coldest, clearest nights.
• Wind: Elevated in the Plains, PNW coasts/gaps, and Rockies downslope zones behind fronts; schedule spraying and light plastic row cover deployment accordingly.
• Heavy Precipitation: Most likely in the Pacific Northwest; lower risk elsewhere, but brief, locally heavier bands possible with frontal passages.
• Fog: Increasing in California’s Central Valley and river-adjacent fields across the South; expect late morning burn-off on some days.
• Fire Weather: Watch for episodic elevated risk on warm, dry, windy days in the High Plains and interior Southwest.

Operational planning checklist

• Prioritize harvest on fields with better drainage and wind exposure to exploit short drying windows.
• Stage row covers or frost protection for high-value horticulture in frost-prone pockets.
• Time fall herbicides and fertilizer around wind thresholds and soil trafficability; avoid saturated periods.
• Service drainage and erosion controls ahead of PNW systems and any frontal showers elsewhere.
• Adjust livestock rations and windbreaks for colder, windy days; ensure unfrozen water access.
• In fog-prone valleys, plan later start times and use lighting/reflective gear for visibility and safety.
