Pollen, Air Quality, and Soil Temperature Forecast – Rowan County

September 21, 2025

Here’s a concise outlook for allergy and gardening concerns across Rowan County through late week.

Pollen Forecast

Main allergens: Ragweed remains the top contributor, with minor grass and mold spores.

• Today–Monday: Overall moderate pollen levels. Light northeast flow and dry afternoons favor ragweed release.

• Tuesday–Wednesday: Levels ease a bit but stay low-moderate; ragweed continues to dominate.

• Thursday–Friday: Increasing clouds and rain chances should knock pollen down, yielding a temporary improvement.

Tips:

• Plan yard work for late morning or after a light shower when pollen is less airborne.

• Rinse off or change shirts after outdoor activities to limit indoor exposure.

Air Quality Forecast

• Today–Tuesday: Good to Moderate range. No widespread issues expected; sensitive groups should limit prolonged activity near busy roads during the warmest part of the afternoon.

• Wednesday–Thursday: Cloud cover and scattered showers should keep readings mostly Good across the county.

• Friday: Behind the front, ventilation improves and air quality should remain Good.

Notes: Light, stable conditions can allow localized buildup near industrial corridors or during evening burn activities, but countywide impacts look limited.

Soil Temperature Forecast (4-inch depth)

• Current: Low 70s°F across most sites.

• Through Wednesday: Holding near the low 70s°F with afternoon highs in the low–mid 80s.

• Late Week into Weekend: A cooler air mass behind Thursday’s front nudges soil temps into the upper 60s°F.

Garden/Lawn Guidance:

• Warm-season grasses remain active; fall overseeding windows are opening as soil slips toward the upper 60s°F.

• New shrub and tree plantings benefit from the late-week cooldown and expected moisture.

Bottom Line

• Allergies: Ragweed remains the primary irritant through midweek; improvement likely late week with rain.

• Air Quality: Generally Good to Moderate, trending Good with the frontal passage.

• Soils: Gradual step down from low 70s°F to upper 60s°F by the weekend—favorable for early fall planting.
