Setting up shop in North Platte, NE today. Quite a marginal setup with relatively low instability / higher based storms based upon Nearcast, higher res LAPS, and more conventional data. Enough shear to organize structures into small line segments at present. Here’s a comparison of some of the higher res model Z output and actual Z at 2100Z. Neither have reality nailed perfectly, but it looks like the OUN-WRF has a slightly better idea of the structure, whereas LAPS has more discrete cells.
