Look at the outflow boundary from the satellite photo above. On this visible image it shows up as a thin cloud line that is well ahead of the surface cold front which remains in western Oklahoma. This cool air has rushed hundreds of miles ahead of the storms along the front; moreover, it could be the key to future thunderstorm development across our area this afternoon.

With sunshine already breaking out, we'll need to watch where this boundary goes, in order to pinpoint where convective initiation will occur. This is a great example of how satellite data can be very useful when creating a forecast.
