LAP Underestimating CAPE A Bit - Still Gave A Reasonable Estimate.

The upper left image shows LAP CAPE, with the cursor readout in a small area of CAPE in clear skies in northern MS. The value was around 262 J/kg, which seemed a little low, compared to the modified NUCAPS soundings and Prob Severe model output around 400 J/kg. The CAPE values elsewhere were in the 150-300 J/kg range in the Memphis CWA. Still, it gave a reasonable idea of how much CAPE was present. Perhaps the lack of clear sky data (see upper right image) may have lead to the slight underestimate. JJW
