What is this?

[Allan Jeffers]

Every so often when I am looking at a radar image I will see like a thin line extending out, such as this one, that looks like an archers bow. I pulled this image from GRlevel3 with a BR of 0.5° and when I click the Base velocity tab, also 0.5° there is a red/green area right about where the blue arch is. There is not much green.





Would this be a gust front?

Looks like an outflow boundary to me.

Yep...that's an outflow boundary.
