The forecaster’s discussion
Written by Pennsylvania Dept. of Environmental Protection for Philadelphia and filed with AirNow.
Current Conditions at 3 p.m. EDT this Friday afternoon: Skies are mostly sunny across the area with ozone and fine particles (PM2.5) at low levels. Good air quality will continue most of the forecast period as wind flow averages from the east. A cool and unsettled pattern will evolve, starting Sunday and continuing into next week with the coolest air felt since last May. Here are the forecast details: *** Saturday’s forecast: Areas of fog to start, then skies turn partly sunny Saturday. Highs will reach the middle 70s with ozone and PM2.5 remaining in the good range on an east to northeast breeze. *** Sunday’s forecast: Mostly cloudy Sunday with showers and a thunderstorm. Highs will reach the lower and middle 70s with continuing low levels of ozone and PM2.5. *** Monday’s forecast: Cooler with overcast skies Monday with highs limited close to 70 degrees as a frontal boundary stalls out just to the south. A few showers are also likely. A brisk onshore flow and cloud cover will keep pollutant concentrations low. *** Extended forecast: The coolest air since last spring will be felt across the region as the fall season starts Tuesday and Wednesday as highs are limited to the lower 60s with a strong cool air damming signal east of the Appalachians. Showers and even a steadier rainy period are likely each day. Fall officially arrives Tuesday evening at 8:04 pm EDT. Air quality continues in the good range. Slow improvements in the weather with seasonally cool air are expected late in the week.---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.

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.
