LightningCast out west

One team of HWT forecasters is in Midland, TX, monitoring convection and serving DSS for the Midland Rockhounds Triple-A baseball team. As we got started, LightningCast for the GOES-17 mesoscale sector is already showing some initiation on the high terrain. However, an outflow boundary heading south-southwest is undercutting some convective cells. LightningCast has higher probabilities, but very few flashes so far behind the outflow boundary. We'll see how the outflow boundary interacts with the rest of the convection.
