Mini Cool Front

This is an image from the National Weather Service NEXRAD radar located in North Little Rock. Thunderstorms earlier in north central Arkansas sent out a gust of cooler air and you can see the leading edge of it moving south. It's called the "outflow boundary". It stretches from near Morrilton to Conway to northern Lonoke county. As the outflow goes past, you're winds can pick up to 20-30 mph and temperatures will drop a few degrees. These boundaries are focus areas for thunderstorm develop again.
