Wondering where that cold air over California is coming from?
Do your own jetstream tracking at home, via NOAA, and find out!

Where's it coming from? Well, she ran a backwards trajectory from the NOAA data, and traced it…to Siberia!
People amaze me. Maybe that marks me as naive, but I'm just going to say it anyhow.
