Air quality is bad today, so bad that when you look outside it looks like thick truck exhaust hanging in the air, like if you took a walk you’d have to shower as soon as you got home.

#pennsylvania #AirQuality #particulates@nancywisser Jeeeez. Do you know if there's a specific cause?

@jwisser I *don't* know. I found this: "Officials say very light surface winds, a temperature inversion, fog, and only light rainfall will act to bring PM2.5 concentrations to the Code Orange level overnight Tuesday and into Wednesday." But it doesn't explain where the particulates are coming from, just that they're trapped here.

@nancywisser A mood, tbh.

@nancywisser @jwisser Yeah, this says pretty much the same thing:
https://www.pennlive.com/weather/2026/02/air-quality-alerts-are-being-extended-in-pa-but-relief-may-come-soon.htmlDavid Martin, a meteorologist for the National Weather Service in State College, said the reason for the continued alerts is very similar to what caused them last week — stale air.
“Weak high pressure has been over the area, so cold air right near the ground where the snow is packed is being trapped,” Martin said. “It’s called inversion, which is where the air mass above the ground is warmer, so it won’t allow the air masses to kind of mix out.”
He explained that this creates stale air and prevents fresh air from circulating through the area. However, the state is expected to receive a mix of snow and rain over the weekend, and Martin estimates that air quality should improve in the coming days.
