Today my pair is operating in the Dodge City, KS county warning area which covers roughly the southwest quadrant of Kansas. As of 1900 UTC, GOES-16 visible imagery and surface obs reveal a well-defined dry line stretching southwest to northeast across the CWA. Analyzing the 1-min visible imagery, cumulus clouds are quickly becoming more agitated in time, with towering cu developing all along the dry line.
LAP CAPE field clear sky algorithm highlights the dry line, with CAPE around 1500 j/kg just ahead of the dry line. This is lower than the adjacent GFS first guess pixels, which are between 2000 and 2500 j/kg. A 1900 UTC DDC souding revealed MLCAPE just over 2000 j/kg. So LAP CAPE bringing CAPE values down slightly too low, but capturing the gradient well.
