Comparison of RAP and GOES-16 CAPE values

While waiting for convection to form in or around the LOT CWA, decided to compare the GOES-16 CAPE data with the RAP 2hr forecast.

In the screenshot below, the RAP BL CAPE is on the left, while the GOES-16 CAPE is on the right.  Both CAPE imagery use the same colortable and values go from 0-5000 J/kg.

In this case, the BL CAPE value from the RAP (18Z run) is significantly higher than the GOES-16 data.  Prior training highlighted the need to focus more on the gradients and less on the values and the GOES-16 data has a fairly decent gradient from higher (2000+ J/kg) to lower (1400-1500 J/kg) values across the ILX CWA.  This gradient matches up fairly well where the edge of the developing cloud field is located.
