Satellite loops showed a diminishing CU field across SJT CWA and surface dew points have been decreasing. AllSkyLAP CAPE has been diminishing over the past couple of hours, but was still near 1500 J/kg. A NUCAPS sounding (Improved Latency) around the same time had CAPE values well under 1000 J/kg and a distinct cap. The CAPE values over the past couple of days have been closer on AllSkyLAP & NUCAPS, and the NUCAPS values have typically been higher. NUCAPS appears to be picking up stability changes more quickly than AllSkyLAP in this case.
