The nearest metar station says there was around 6mph of wind. But this station is more local and doesn't appear to be installed at 10m height (as a metar station is)... this station appears to be within the sightline of the shooter and Kirk; so it would be far more accurate per this situation.
Another still photo, more wide angle. You can see the David VantagePro2 weather station relative to Kirk's location here.
Wonder if that crowd realizes hate speech isn’t free. Looks like nice people…
That’s funny I look for weather stations when I travel. And also USGS location markers.
I was actually trying to figure out what kind of wind conditions were present during the shooting, so I was scanning videos for flags and then... there it was.
