Initial NUCAPS (below) had a low SBCAPE, based on dry conditions. Temperature looked good on original sounding, but when I moistened the environment up (image above), got to the 4500-5000 CAPE SPS meso was showing earlier. Large spread of dewpoints over the area, likely b/c of topography? Perhaps the RUC smoothes over those dewpoint changes and that’s the reason SPC meso had the large CAPE.
