AshburnWeather.com is Back Online!

Good news! The weather station is up and running again. A recent power outage caused a slight configuration issue that temporarily stopped data from publishing to the website. That’s now fixed.

I’ll be working to restore the missing historical data using exports from Weather Underground. If you're curious, you can view the full data set here:

Thanks for your patience, and stay tuned for more updates!

Added a filter for the AQI reading shown on ashburnweather.com to require a PM2.5 reading. Broad Run High School reports an AQI of 0 on the Aeris Weather API for some reason, so using a different station for that, now.
