This is an interesting snapshot of what we are seeing in the US right now with EPA sites spread from West to East coast (including my nearby EPA station) reaching highs above their normal average recorded levels causing them to show ALERT status on NETC. I can confirm these recorded higher levels with my own units that are connected to NETC because mine went up too, I just can't confirm the exact level due to different equipment being used. Members can look at my graphs in Northern Illinois and see what I am talking about. In fact, once my nearby EPA site updates again it will go higher than currently recorded. I know this because my units went higher too.



Seems to match the path of the current jet stream too!
