The forecaster’s discussion

Written by Pennsylvania Dept. of Environmental Protection for Erie and filed with AirNow.

Current Conditions at 4 PM EDT this Monday afternoon: Bouts of light rain are moving through the area, with temperatures struggling in the lower 60s. The cool air is arriving almost in time for the start of fall, which begins at 8:04 pm EDT Tuesday. Air quality is well down inside the good range and will continue to be so through the forecast period. Here are the forecast details: *** Tuesday’s forecast: Mostly cloudy with a cool wind Tuesday. An easterly wind will keep ozone and PM2.5 concentrations low. Highs will top out around 60 degrees. *** Extended forecast: High pressure working it’s way southwestward from Canada will allow for seasonably cool and dry conditions later this week. Temperatures will moderate some by the weekend with air quality possibly deteriorating a bit Saturday or Sunday due to less mixing and morning inversions. Air quality, however, should remain in the good range.---McAuliffe

Fine particles in micrograms per cubic meter, ozone in parts per billion as an 8-hour average. The index for each hour is EPA’s: the ozone figure is already the 8-hour average the ozone index is defined on, and the particle figure is run through EPA’s NowCast, which is how an hourly PM2.5 concentration becomes an index.

Smoke

NOAA’s analysts have not drawn smoke over Ripley in satellite imagery today.

NOAA’s model forecasts no measurable smoke near the ground here over the next two days.

Category descriptions are the Environmental Protection Agency’s own.

What these numbers are. An index beside a monitor’s name is a measurement, published hourly by AirNow and preliminary until the operating agency certifies it. A category for today or tomorrow is a state or local agency forecaster’s own forecast for a reporting area. An hourly index is NOAA’s air quality model on a five-kilometer grid, not a reading from any instrument. Where a town has no monitor within reach, only the model figures appear, and the page says so.
