Outflow/TPW/MetOPs A

Series of pictures showing the derived TPW picking up on increased moisture behind an outflow boundary. Lower dewpoints in the post outflow area (mid/upper 60s) vs. ahead of boundary (70-72). Soundings show the lower TPW in southern MO vs. higher TPW near Topeka (like the derived ABI). Actual numbers are little different but trends similar.
