ENVIRONMENT & ANALYSIS

Local Environmental Conditions

Around Severance Township, no major forest, water, or park sits nearby, so open-ground grass and roadside ragweed likely account for most local pollen. As with most local readings, actual levels can vary somewhat with short-term weather swings. The general pattern described here holds fairly steady across nearby areas with similar land cover.

Around Severance Township, late spring sees grass pollen build steadily toward a peak in June, then yields to ragweed, the dominant late-summer and fall allergen through October. Neighboring parts of the county typically see this same sequence with only minor timing shifts. The overall order of species tends to hold steady, even as exact dates shift slightly each year.

How often is the Severance Township pollen forecast updated?

The Severance Township pollen forecast is updated four times daily. See the timestamp below for the most recent update.

Does pollen in Severance Township come from nearby or far away?

Studies show that most pollen exposure (often 70–90%) comes from nearby sources, such as local trees and vegetation. A good pollen forecast therefore depends on accurately representing local vegetation. Pollen can travel long distances, but this usually matters only early in the season or during specific wind events.

Are pollen levels in Severance Township based on measurements or forecasts?

Pollen data is often misunderstood. Most "pollen levels" are not real-time measurements, but forecasts.

Direct pollen measurements are typically delayed by 1-2 days because they require manual analysis. To show current conditions in Severance Township, modern forecasts combine recent measurements, weather data, and information about local vegetation.

This allows us to estimate pollen levels for today and the coming days, not just report the past.

Understanding the Scale

The 0–100 scores represent risk levels, not direct measurements of pollen or air pollutant concentrations. Higher scores indicate higher risk. Pollen and air quality use different thresholds.

Pollen

None
0 No or negligible risk of exposure. Pollen/mold exposure is expected to be minimal.
Low
0-25 Low risk of exposure. Small amounts of pollen or mold spores may be present.
Moderate
25-50 Moderate risk of exposure. Pollen/mold exposure is expected to be noticeable.
High
50-75 High risk of exposure. Elevated pollen/mold exposure is expected.
Very High
75-100 Very high risk of exposure. Pollen/mold exposure is expected to be at or near its highest levels.
